   Before BAUER, MANION, and KANNE, Circuit Judges.
    MANION, Circuit Judge. Louquetta O’Connor-Spinner, who
is 47, suffers from depression and several physical impair-
ments. Several times since 2001 she has applied for Disability
Insurance Benefits and Supplemental Security Income, and
six years ago we invalidated the Social Security Administra-
tion’s denial of her 2004 request for benefits. O’Connor-Spinner

v. Astrue, 

(7th Cir. 2010). We concluded that the
assigned administrative law judge had committed two errors
relating to O’Connor-Spinner’s depression. First, the ALJ had
not asked a testifying vocational expert to assess how O’Con-
nor-Spinner’s employment prospects would be affected by
her moderate limitation on concentration, persistence, and
pace. And, second, the ALJ had ignored a psychologist’s opin-
ion that O’Connor-Spinner also faces a moderate limitation on
her ability to accept instructions from, and respond appropri-
ately to, supervisors. We instructed the Agency to remedy
these mistakes, but instead of complying with this simple di-
rective, a different ALJ contradicted his colleague and de-
clared that O’Connor-Spinner’s depression is not, and never
has been, a severe impairment. O’Connor-Spinner again has
sought judicial review, and she argues that the medical evi-
dence contradicts this assertion. We agree, and once more we
must remand this case to the Agency for further proceedings.
                          I. Background
    As we did in our previous opinion, we omit discussion of
O’Connor-Spinner’s physical impairments because the par-
ties agree that those afflictions—degenerative disk disease, bi-
lateral carpal tunnel syndrome, sleep apnea, “restrictive lung
disease,” and obesity—are severe and would themselves limit
O’Connor-Spinner to sedentary work. The effect of O’Con-
nor-Spinner’s depression on her ability to maintain employ-
ment is, as before, the sole issue on appeal.
   Evidence of O’Connor-Spinner’s depression predates the
December 2003 onset date that she alleged when applying for
benefits in 2004. Doctors treating her physical ailments had
described O’Connor-Spinner as appearing depressed, noted a
No. 15-2567                                                                 3

history of depression, and catalogued prescriptions for anti-
depressants. O’Connor-Spinner had visited a community
mental-health center three times during 2002. Progress notes
document her reports of recurring agitation, impulsivity, fa-
tigue, and crying spells, as well as two or three “explosive ep-
isodes” weekly involving violent behavior and memory
blackouts. O’Connor-Spinner also had recounted suicide at-
tempts and difficulty managing anger (the latter prompting a
court to grant a neighbor’s request for a restraining order).
Clinicians had diagnosed depression and an “adjustment dis-
order with mixed disturbance of emotions and conduct.” This
type of adjustment disorder is marked by “clinically signifi-
cant emotional or behavioral symptoms” of both depression
and conduct disturbances such as “violation of the rights of
others or of major age-appropriate social norms and rules.”
AM. PSYCHIATRIC ASS’N., DIAGNOSTIC & STATISTICAL MANUAL
OF MENTAL DISORDERS 679–80 (4th ed. text revision 2000).
O’Connor-Spinner was prescribed the antidepressants Elavil
and Prozac. During these visits her Global Assessment of
Functioning 1 had been scored at 50, 52, and 55; a score of 50
indicates serious symptoms or “serious impairment in social,
occupational, or school functioning,” while scores between 51
and 60 indicate moderate functional difficulty or symptoms.

see also Price v. Colvin, 

, 839 (7th Cir.
2015). Even so, a state-agency psychologist who reviewed


    1 The Global Assessment of Functioning, or “GAF,” measures the se-
verity of a patient’s symptoms or level of functioning on a scale of 0 to 100.
Although the American Psychiatric Association no longer uses this metric,
see AM. PSYCHIATRIC ASS’N, DIAGNOSTIC & STATISTICAL MANUAL OF
MENTAL DISORDERS 16 (5th ed. 2013), the GAF was still in use at the time
of the psychiatric evaluations recounted in this record.
4                                                 No. 15-2567

O’Connor-Spinner’s medical records in October 2002 (in con-
nection with her 2001 application for benefits) had opined
that she didn’t have a severe mental impairment at that time.
    No mention of psychological counseling appears in
O’Connor-Spinner’s medical records for the three years fol-
lowing that psychologist’s review, but medical providers
treating her physical ailments in 2004 and 2005 alluded to her
history of depression and noted current prescriptions for an-
tidepressants. And in May 2004 a different state-agency psy-
chologist, Dr. Kamla Paul, examined O’Connor-Spinner and
specifically diagnosed a depressive disorder. Dr. Paul noted
many of the same symptoms documented in 2002, including
crying fits and violent outbursts—in one of the latter, O’Con-
nor-Spinner had threatened her husband with a butcher knife.
Although Dr. Paul rated as adequate many of O’Connor-
Spinner’s abilities, including abstract thinking and long-term
memory, the doctor gauged her general knowledge and
short-term memory as poor and remarked that “she gets con-
fused.” Dr. Paul noted that O’Connor-Spinner was dysphoric
and showed a flat affect, and assigned her a GAF of 55.
    Later that same month, a third state-agency psychologist,
Dr. Donna Unversaw, reviewed the medical file. She opined
that O’Connor-Spinner’s depression caused a moderate limi-
tation on concentration, persistence, and pace, although she
asserted (without explanation) that this limitation would not
prevent O-Connor-Spinner from performing moderately
complex tasks. Dr. Unversaw also opined that O’Connor-
Spinner had moderate difficulty accepting instructions from
supervisors and responding appropriately to their criticisms.
   At O’Connor-Spinner’s hearing before the first ALJ in Jan-
uary 2006, she testified that she thinks frequently of suicide,
No. 15-2567                                                    5

sleeps for days at a time, rarely leaves home, and skips social
activities that she once enjoyed. A vocational expert, respond-
ing to a “hypothetical” from the ALJ listing O’Connor-Spin-
ner’s physical limitations but not her limitation on concentra-
tion, persistence, and pace or her difficulty relating to super-
visors, testified that she could perform several jobs existing in
significant numbers in the national economy. In a written de-
cision issued in June 2006, the ALJ concluded at Step 2 of the
5-step      analysis,    see 20   C.F.R.   §§ 404.1520(a)(4)(ii),
416.920(a)(4)(ii), that O’Connor-Spinner’s depression was se-
vere (as were her physical ailments). The ALJ found that she
was not disabled, however, reasoning at Step 5 that she re-
tained the ability to perform the simple, sedentary jobs iden-
tified by the vocational expert. The Appeals Council declined
review.
    O’Connor-Spinner sought judicial review, see 42 U.S.C.
§ 405(g), and though a district judge upheld the ALJ’s deci-
sion, we agreed with O’Connor-Spinner that the ALJ should
have included her moderate limitation on concentration, per-
sistence, and pace among the limitations given to the voca-
tional expert. See 

–21. In
reaching this conclusion, we specifically rejected the Commis-
sioner’s argument that the ALJ necessarily had incorporated
this limitation by restricting O’Connor-Spinner to simple, re-
petitive tasks. 

We also concluded that the ALJ
should have addressed Dr. Unversaw’s opinion that O’Con-
nor-Spinner suffered from a moderate limitation on her abil-
ity to accept instructions and criticism from supervisors since,
as Social Security Administration regulations make clear,
“even a moderate limitation on responding appropriately to
supervisors may undermine seriously a claimant’s ability to
6                                                 No. 15-2567

work.” 

C.F.R. § 404.1545(c); SSR 85-15). We di-
rected the Agency to remedy these two shortcomings.
    Our opinion reversing the district court was issued in No-
vember 2010, but for reasons not disclosed in the record, the
Social Security Administration did not act on that decision
until April 2012. By then more than six years had passed since
O’Connor-Spinner’s hearing before the ALJ, and she supple-
mented the record with evidence accumulated during that pe-
riod. Records show that in March 2006—after the hearing but
three months before the ALJ’s decision—she had returned to
the community mental-health center seeking help with symp-
toms of depression and anxiety. This time she was diagnosed
with “major depression, recurrent severe.” A diagnosis of
“major depression” means, by definition, that an individual’s
“symptoms cause clinically significant distress or impairment
in social, occupational, or other important areas of function-
ing.” AM. PSYCHIATRIC ASS’N, supra at 356. O’Connor-Spin-
ner’s GAF score once again was recorded as 50, indicating se-
rious symptoms or functional impairments. The diagnosis of
major depression is repeated in records from 2007 and 2008.
So are O’Connor-Spinner’s self-reports of suicidal thoughts.
One therapist documented an incident in which O’Connor-
Spinner, in a fit of anger, had discarded all of her medica-
tions—prompting her husband to remove his guns from their
home “for safety.”
   Dr. Robert Kurzhals, a fourth state-agency psychologist,
had examined O’Connor-Spinner in December 2009 (after she
again applied for benefits while her previous appeal was un-
der consideration in this court). O’Connor-Spinner had re-
ported feeling depressed most days and said that about eight
times a month she stays home because of her depression.
No. 15-2567                                                  7

Dr. Kurzhals had observed that O’Connor-Spinner was mar-
ginally groomed, slow-speaking, depressed, and “perhaps
mildly impaired” in concentration and attention. He also had
noted without comment that, when tested, she could recall
only five digits forward and three digits backward (this same
result prompted the earlier examining physician, Dr. Paul, to
conclude that O’Connor-Spinner’s short-term memory was
“poor”). When asked to count down from one hundred by
sevens (a common technique, called “serial sevens,” for as-
sessing concentration and memory), O’Connor-Spinner
counted on her fingers and slowly responded, “92, 84, 77, 70,
63, 56, 48.” Dr. Kurzhals had written that she “presented as a
depressed and somewhat irritable individual,” diagnosed
O’Connor-Spinner as bipolar (based on her self-reported his-
tory of suffering from the disorder), and assigned her a GAF
score of 51.
     Also in December 2009, yet another state-agency psy-
chologist, Dr. William Shipley, had reviewed O’Connor-Spin-
ner’s medical records and opined, without an examination,
that her mental impairment was not severe. Dr. Shipley
checked a box on a form to indicate that O’Connor-Spinner
suffered from bipolar disorder (based solely on the opinion of
Dr. Kurzhals), but he failed to reconcile this conclusion with,
or even acknowledge, the diagnoses of depression and, later,
major depression from her treatment providers. Neither did
he comment on the explicit diagnosis of a “depressive disor-
der” given by Dr. Paul, the first of the two state-agency psy-
chologists who examined O’Connor-Spinner. Dr. Shipley
ticked off evidence that, in his view, proved her “social func-
tioning and concentration … to be intact”: O’Connor-Spinner
still was capable … of attending to her own personal hygiene
8                                                    No. 15-2567

(although that ability was “marginal,” according to Dr. Kur-
zhals); she could shop in stores, manage money, and drive;
and she enjoyed watching TV. He then questioned O’Connor-
Spinner’s credibility, and concluded that she was only mildly
limited in the three categories used in evaluating the effects
of mental illness: activities of daily living; social functioning;
and concentration, persistence, and pace. Thus, Dr. Shipley
had said, it was “reasonable to conclude that the claimant’s
condition is not severely limiting at this time.”
    Apart from contradicting the existing evidence, Dr. Ship-
ley’s assessment also stands in stark contrast to the conclu-
sions of medical providers who continued to treat O’Connor-
Spinner. In March 2010, a few months after Dr. Shipley of-
fered his assessment, a nurse practitioner specializing in pain
management had examined O’Connor-Spinner. The nurse
practitioner had noted significant signs of depression, re-
marked on the limited efficacy of O’Connor-Spinner’s pre-
scribed antidepressants, and recorded her revelation that
more often than not she thinks she’d be better off dead.
O’Connor-Spinner continued taking those medications, how-
ever, and later in 2010 a clinician at the community mental-
health center had written that she “presented as depressed
and her affect was constricted,” that her cognition was im-
paired, and that she “struggled” with both serial sevens and
fours. The clinician opined that the effectiveness of O’Connor-
Spinner’s medications should be evaluated, repeated the di-
agnosis of “major depressive disorder, recurrent," and as-
signed her a GAF score of 55.
   About a year later, near the end of 2011, O’Connor-Spin-
ner told a psychiatrist at the community mental-health center
that her medications were working well and her depression
No. 15-2567                                                    9

had improved. Although the doctor wrote that O’Connor-
Spinner seemed happier and more stable, her GAF score re-
mained at 55.
    Meanwhile, our simple directive to remedy the first ALJ’s
missteps in addressing O’Connor-Spinner’s mental limita-
tions was never carried out. Instead the Agency reassigned
the case to a different ALJ, who in June 2012 reopened the ev-
identiary hearing. The new ALJ posed to a different voca-
tional expert—the only witness—a “hypothetical” that, ac-
cording to the ALJ, was “based on the previous ALJ’s find-
ing.” True, the new ALJ’s hypothetical incorporates all of
O’Connor-Spinner’s physical restrictions, but it does not men-
tion her limitation on concentration, persistence, and pace,
nor does it say anything about difficulties in responding ap-
propriately to supervisors. After the vocational expert had
identified several jobs that could be performed by someone
with the listed physical restrictions, the ALJ asked if the voca-
tional expert’s opinion would be different if “due to limita-
tions in concentration, persistence, or pace … this person can-
not do any work involving strict production quotas or fast
paced.” The vocational expert replied that his opinion would
not change because, he explained, he already had excluded
jobs which require “constant handling and fingering.” The
ALJ then asked if the same jobs would be available to a person
who would be “off task” for 10% of the workday. That degree
of distraction, the vocational expert replied, would be tolera-
ble for unskilled work. But, he added, at more than 15% the
person would be “very unlikely” to maintain employment.
O’Connor-Spinner’s attorney then asked if a “moderate” lim-
itation on the “ability to accept instructions and respond ap-
propriately to criticism from supervisors” would further limit
10                                                  No. 15-2567

the jobs available to someone with O’Connor-Spinner’s phys-
ical limitations. Counsel defined “moderate” as 15% to 20%
below normal, prompting the vocational expert to reply that
this limitation would undermine the ability to maintain em-
ployment and, if persistent, “would likely cause significant
problems, meaning to retain the jobs.”
    In a written decision, the new ALJ found that O’Connor-
Spinner had not engaged in substantial gainful activity since
2003 (Step 1); that her degenerative disc disease, bilateral car-
pal tunnel syndrome, sleep apnea, lung disease, and obesity
(but not her major depression) constituted severe impair-
ments (Step 2); that none of these impairments, alone or in
combination, met or equaled a listed impairment (Step 3); that
she had the residual functional capacity to perform sedentary
work with several physical restrictions (Step 4); and that
given her age, education, work experience, and residual func-
tional capacity O’Connor-Spinner could perform jobs which
exist in significant numbers and thus wasn’t disabled (Step 5).
Although the ALJ had identified the salient issue on remand
as “the claimant’s depression and what, if any, work-related
limitations it causes,” the bulk of his analysis concerns his re-
jection at Step 2 of depression as a severe impairment.
    That analysis acknowledges our previous opinion, but in-
stead of complying with our instructions, the new ALJ as-
serted that “both errors cited by the court in its review of the
case were based on the convoluted assessment by Dr. Unver-
saw … that is internally inconsistent, virtually incoherent,
and totally unsupported.” The ALJ gave three reasons for ex-
coriating Dr. Unversaw: (1) on a worksheet she had described
O’Connor-Spinner’s difficulty with concentration, persis-
No. 15-2567                                                 11

tence, and pace as mild but then, in assessing her mental re-
sidual functional capacity, concluded that O’Connor-Spinner
was moderately limited; (2) the psychologist’s opinion that
O’Connor-Spinner had difficulty relating to supervisors was
communicated by marking a form instead of through narra-
tive; and (3) Dr. Unversaw had not, in the ALJ’s view, sup-
ported her findings adequately.
    Dr. Unversaw’s evaluation, the ALJ insisted, “stands
alone in suggesting severe depression with two moderate lim-
itations.” The ALJ acknowledged that (shortly after her Janu-
ary 2006 hearing) O’Connor-Spinner had been diagnosed
with major depression, but he did not mention that the precise
diagnosis was “major depression, recurrent severe.” Neither
did he explore the import of the specific diagnosis. The ALJ
referred only in passing to Dr. Kurzhals’s most recent exami-
nation of O’Connor-Spinner for the state agency, without dis-
cussing any of the psychologist’s statements supporting
O’Connor-Spinner’s claim of disability. Instead the ALJ cred-
ited the opinion issued a few days later by Dr. Shipley, who
decided without examining O’Connor-Spinner that her depres-
sion was not a severe impairment.
   In accepting that opinion, the ALJ minimized the import
of a decade of records from the community mental-health
center. Those records document treatment for, and recurrent
symptoms of, O’Connor-Spinner’s major depressive disorder,
but the ALJ focused on her latest visit at the end of 2011 when
she had reported improvement. And, while blinding himself
to documentation of the symptoms she did experience, the
ALJ stated that O’Connor-Spinner’s treatment records “pro-
vide little or no information about any problems with social
12                                                 No. 15-2567

functioning or concentration, persistence, and pace” (this de-
spite the fact that clinicians at the mental-health center were
tasked with treating O’Connor-Spinner’s depression, not
evaluating her ability to work). The ALJ also weighed against
O’Connor-Spinner her purported “lack of mental health treat-
ment” between 2002 and 2006, when, in fact, throughout that
time she was taking antidepressants that only a medical pro-
vider treating her depression would have prescribed. Moreo-
ver, the new ALJ rejected outright the consistent reports from
different practitioners—including both of the examining psy-
chologists hired by the Agency—that O’Connor-Spinner had
GAF scores ranging from 50 to 55. The ALJ brushed aside
those scores, which signal moderate to severe functional lim-
itations, as “subjective” and having “little value.”
   The ALJ then observed that physicians treating O’Connor-
Spinner’s physical ailments had not mentioned the specific
mental limitations underlying our previous opinion:
     Furthermore, in all of the voluminous documents that
     address physical impairments, there is scarcely even a
     hint of significant problems with social functioning or
     concentration, persistence and pace. Indeed, indica-
     tions of mental issues are conspicuously absent from
     those records. It is reasonable to assume that if the
     claimant were rude and discourteous to her doctors, if
     she reacted inappropriately to their “criticism” (such
     as repeated admonitions to lose weight), or if she were
     having a difficult time concentrating, it would have
     been observed and mentioned somewhere in the hun-
     dreds of pages of medical records.
No. 15-2567                                                     13

The ALJ gave as an example that nurses attending O’Connor-
Spinner during an overnight hospital stay had not docu-
mented any “mental aberrations,” which must mean, the ALJ
reasoned, that her depression was not severe.
   The ALJ then concluded:
   Therefore, in response to the court’s remand order, the
   undersigned finds that the claimant’s depression has
   never been a severe impairment. Accordingly, she does
   not have—and never did have—a moderate limitation
   in concentration, persistence, or pace that would re-
   quire corresponding work-related limitations in her re-
   sidual functional capacity. The undersigned also re-
   jects Dr. Unversaw’s opinion that she has a moderate
   limitation in social functioning that impacts her ability
   to accept instructions and respond appropriately to
   criticism from supervisors.
    The district court upheld the ALJ’s decision, so the ALJ’s
ruling is the final decision of the Commissioner of Social Se-
curity. See Liskowitz v. Astrue, 

, 739 (7th Cir. 2009).
                           II. Discussion
    On appeal O’Connor-Spinner contends that the ALJ mis-
characterized her depression as not severe and, consequently,
failed to “capture the full scope of her emotional limitations”
in framing questions to the vocational expert. The Commis-
sioner, while saying that O’Connor-Spinner simply com-
plains about a handful of “notations” in the medical record
which the ALJ “overlooked,” actually understands the central
issue in this case to be the ALJ’s rejection at Step 2 of depres-
sion as a severe impairment. The Commissioner devotes her
brief to arguing that the ALJ considered all evidence “he
14                                                 No. 15-2567

found important” and was not required to comment on each
piece of evidence cited by O’Connor-Spinner. Yet never does
the Commissioner explicitly argue that the ALJ’s Step 2 find-
ing, if erroneous, was harmless or that the ALJ actually fol-
lowed the instructions we gave in returning this case to the
Agency.
    Had the new ALJ followed our narrow instructions to ad-
dress the shortcomings in his predecessor’s decision, this ap-
peal would be simple (if necessary at all). But instead the ALJ
reevaluated O’Connor-Spinner’s condition himself and, de-
spite new evidence that strengthens the earlier finding that she
suffers from severe depression, found the opposite.
    Having reviewed the record, we cannot agree with the
Commissioner’s assertion at oral argument that a “mountain
of evidence” supports the ALJ’s rejection of depression as a
severe impairment. The Step 2 determination is “a de minimis
screening for groundless claims” intended to exclude slight
abnormalities that only minimally impact a claimant’s basic
activities. Thomas v. Colvin, __ F.3d __, No. 15-2390, 

, at *5 (7th Cir. June 22, 2016). But here the ALJ de-
cided that “major depression, recurrent severe” isn’t a severe
impairment based on the opinions of two state-agency psy-
chologists who did not even examine, let alone treat, O’Con-
nor-Spinner. That determination is not supported by substan-
tial evidence and, indeed, strikes us as nonsensical given that
the diagnosis, by definition, reflects a practitioner’s assess-
ment that the patient suffers from “clinically significant dis-
tress or impairment in social, occupational, or other important
areas of functioning.” AM. PSYCHIATRIC ASS’N, supra at 679–80.
We have not found a published opinion from any circuit in
which an ALJ declared that major depression was not a severe
No. 15-2567                                                 15

impairment, although two unpublished decisions soundly re-
ject this assertion, see Magwood v. Comm’r, 417 F. App’x. 130
(3d Cir. 2008); Wick v. Barnhart, 173 F. App’x. 597 (9th Cir.
2006). Rather than relying on the guidance of professionals
and evidence from O’Connor-Spinner’s treating sources, the
ALJ “played doctor” by substituting his opinion for their
medical judgment.
    The ALJ’s decision is replete with examples of cherry-
picking evidence supporting his finding while ignoring
contradictory information. See Bates v. Colvin, 

,
1099 (7th Cir. 2013) (reversing because ALJ had ignored line
of evidence supporting claim of serious mental-health issues);
Scrogham v. Colvin, 

, 698–700 (7th Cir. 2014)
(reversing because ALJ had disregarded evidence
undermining finding that claimant wasn’t disabled). The ALJ
said nothing about progress notes from treatment providers
that document serious symptoms (i.e., suicidal thoughts,
angry and violent behavior, and staying in bed on multiple
days per month), yet he singled out the one record
documenting a period when O’Conner-Spinner’s symptoms
had waned. See Larson v. Astrue, 

, 751 (7th Cir.
2010) (observing that “symptoms that ‘wax and wane’ are not
inconsistent with a diagnosis of recurrent, major depression);
Bauer v. Astrue, 

, 609 (7th Cir. 2008) (noting that
person whose chronic mental illness is treated with heavy
drugs likely will experience better and worse days). The ALJ
inexplicably drew a negative inference from the fact that
doctors treating O’Connor-Spinner’s physical ailments had
not commented on her concentration, memory, or social
functioning. The ALJ seized on Dr. Kurzhals’s observation
that O’Connor-Spinner did not appear manic, yet he ignored
the psychologist’s further observations that O’Connor-

Spinner was depressed and irritable and had performed
poorly on memory tests during the examination. What is
more, the ALJ berated Dr. Unversaw’s findings as “virtually
incoherent” because of what appears to be a typo. Overall the
ALJ was wrong to conclude, despite the plethora of evidence
to the contrary, that O’Connor-Spinner’s depression was not
severe.
    Because the new ALJ eliminated depression at Step 2, he
did not take into account any effects which the disorder might
have on O’Connor-Spinner’s ability to maintain employment.
The ALJ thus failed to “build an accurate and logical bridge
between the evidence of mental impairments” and his ulti-
mate conclusion that O’Connor-Spinner remains capable of
performing sedentary work. See Yurt v. Colvin, 

,
858–59 (7th Cir. 2014); 

–21.
Had the ALJ not excluded depression at Step 2, he would
have been required to fully explore the restrictions caused by
O’Connor-Spinner’s depression. See Villano v. Astrue, 

, 563 (7th Cir. 2009). Given the considerable additional ev-
idence introduced after our remand to the Agency, including
the diagnosis of “major depression, recurrent severe,” it is in-
conceivable that O’Connor-Spinner’s depression was less
likely than before to impede her ability to work. Greater re-
strictions are more probable, but, at the very least, the ALJ
was compelled—as we said before—to account for O’Connor-
Spinner’s limitation on concentration, persistence, and pace
and also to address—not ignore—Dr. Unversaw’s opinion
that she is moderately limited in responding appropriately to
supervisors.

    To her credit the Commissioner does not defend the new
ALJ’s assertion that he accomplished the objective of our re-
mand even while explicitly declining to follow our instruc-
tions. According to the ALJ, even if he
   had found a moderate limitation in concentration, per-
   sistence, or pace and added a restriction to work with-
   out strict production quotas or fast pace, the [voca-
   tional expert] testified it would not affect the jobs he
   named, because the inability to perform constant han-
   dling and fingering had already eliminated most fast-
   paced jobs.
The ALJ specifically had asked the vocational expert whether,
because of “limitations in concentration, persistence, or pace
... this person cannot do any work involving strict production
quotas or fast pace.” Yet the Commissioner has not cited, nor
have we found, any authority supporting the ALJ’s specula-
tion that eliminating jobs with strict production quotas or a
fast pace may serve as a proxy for including, as part of the
claimant’s mental residual functional capacity, a moderate
limitation on concentration, persistence, and pace. Perhaps
the vocational expert would have substantiated that specula-
tion if asked, but, as before, the ALJ did not ask.
    That the ALJ did not ask is especially troubling given the
vocational expert’s concession that O’Connor-Spinner would
be “very unlikely” to maintain employment if she was off task
15% or more of the time, or if she had difficulty responding
appropriately to supervisors. Agency regulations, as far as we
can tell, do not quantify what is meant by a “moderate” re-
striction, but the regulations do instruct ALJs to rate the de-
gree of limitation on a 5-point scale of none, mild, moderate,
marked, and extreme. See 20 C.F.R. § 404.1520a. If a moderate
18                                                No. 15-2567

impairment on maintaining concentration, persistence, and
pace equates to being off task at least 15% of the time then,
according to the vocational expert, O’Connor-Spinner is es-
sentially unemployable. This testimony at least calls into
question the ALJ’s assertion that eliminating jobs which re-
quire strict production quotas or a fast pace sufficiently ac-
counts for a moderate limitation on concentration, persis-
tence, and pace.
                       III. Conclusion
    Ten years ago the first ALJ to address O’Connor-Spinner’s
impairments committed errors that prompted us to return the
case to the Agency with simple instructions. And six years af-
ter our remand the matter remains unresolved because the
new ALJ failed to comply with our instructions. Accordingly,
we VACATE the judgment of the district court and REMAND
the case to the Agency for further consideration. On remand
the ALJ should determine what limitations are caused by
O’Connor-Spinner’s “major depression, recurrent severe”
and fully explore with a vocational expert the effect of those
limitations on O’Connor-Spinner’s ability to engage in com-
petitive employment.
