MELLOY, Circuit Judge.

      Petitioner-Appellant Robert Johnson appeals the district court’s1 order
affirming the Commissioner’s determination that he was not disabled. We affirm.



      1
       The Honorable John F. Forster, Jr., United States Magistrate Judge for the
Eastern District of Arkansas
                                         I.


       Johnson applied for supplemental security income (SSI) on March 10, 1997.
He alleged that he was disabled due to headaches, low back pain, hip pain, and pain
in his arms and hands. Johnson subsequently added depression as a claimed mental
impairment.


       At the request of the Social Security Administration (SSA), Dr. Trent Marcus,
M.D., Johnson’s family physician, examined Johnson. Dr. Marcus diagnosed
Johnson to have chronic low back pain with osteoarthritis, non-cardiac chest pain,
headaches, hypertension, and possible depression. Dr. Marcus documented that
Johnson did not have neurological or psychiatric problems (other than the possible
depression). The physical exam showed that Johnson did not have difficulty with his
ears, neck, lungs, gait, coordination, or limb function. Dr. Marcus found Johnson to
have normal range of motion in his spine, shoulders, elbows, wrists, hands, hips,
knees, and ankles.


       On July 23, 1998, Dr. Richard C. Maddock, Ph.D., a psychologist, performed
a psychological evaluation of Johnson, also at the request of the SSA. Dr. Maddock
documented that the Wechsler Adult Intelligence Scale - Revised test revealed that
Johnson had a verbal IQ of 64, a performance IQ of 60, and a full scale IQ of 58. Dr.
Maddock recorded that on the Wide Range Achievement Test-3, Johnson had
difficulty with all areas, including understanding the instructions given to him. On
the Wahler Physical Symptoms Inventory test, Johnson’s results “strongly suggest[ed]
both somatic components to his complaints and malingering.” His score “suggested
[a] gross exaggeration of symptoms.” Results of the Minnesota Multiphasic
Personality Inventory-2 test, indicated that Johnson answered randomly to the
questions. Dr. Maddock concluded that little or no weight should be given to the


                                        -2-
results of the Minnesota Multiphasic Personality Inventory-2 test because it had not
been completed properly. Dr. Maddock determined that Johnson was malingering
and diagnosed him with alcohol abuse, borderline personality disorder, and hip and
back pain.


       Johnson’s application was denied initially and on reconsideration. Following
a hearing at which Johnson was represented by counsel, an administrative law judge
(ALJ) denied Johnson’s disability application. On May 11, 2001, the Appeals
Council remanded the case for further administrative proceedings.


        Dr. Maddock tested Johnson again on September 24, 2001 at the request of the
SSA. Dr. Maddock conducted a Full Psychological Test Battery, Mental Status and
Evaluation of Adaptive Functioning (Adult). Again, a Minnesota Multiphasic
Personality Inventory-2 test indicated Johnson answered randomly without regard to
the content of the question. Dr. Maddock concluded that little or no weight should
be given to this exam since Johnson’s psychological profile appeared to be invalid.
Dr. Maddock stated that failure to accurately respond to test items may have been due
to lack of cooperation, malingering, or to confusion on Johnson’s part. Dr. Maddock
also documented that Johnson’s Wechsler Memory Scale - Revised scores were not
consistent with his scores on the two other tests of intellectual ability. Dr. Maddock
stated that such large variations in test scores are unusual. Dr. Maddock also noted
that although Johnson complained of a poor memory, the scores indicated his memory
was particularly strong. However Dr. Maddock did note in his report that the
consistency of Johnson’s scores on the Wechsler Adult Intelligence Scale - Revised
indicated some degree of reliability as to those scores. Yet, Dr. Maddock was
concerned that the consistency of the scores might also have been due to malingering.
Finally, Dr. Maddock administered the Computerized Assessment of Response Bias
exam. This test is given when a person is believed to be malingering. Johnson’s test
results indicated strong evidence of malingering. Despite unreliable test results due

                                         -3-
to Johnson’s malingering, Dr. Maddock diagnosed Johnson with alcohol abuse and
mild mental retardation. Dr. Maddock questioned the reliability of his conclusions,
however, because Dr. Maddock believed that Johnson had not been open and honest
during the interview and there was evidence of malingering and exaggeration of
symptoms.


       At a subsequent administrative hearing on November 20, 2001, Johnson was
again represented by counsel and presented testimony, including the opinion of a
vocational expert. On December 26, 2001, the ALJ found that: 1) Johnson was not
under a disability as defined by the Social Security Act; 2) Johnson did not meet or
equal any of the listed impairments listed in Appendix 1, Subpart P, Regulation No.
4; and 3) Johnson’s past relevant work did not require the performance of work-
related activities precluded by his physical and mental residual functional capacity.
The ALJ denied Johnson’s application. On March 27, 2002, the Appeals Council
denied Johnson’s request for review, making the ALJ’s decision the Commissioner’s
final decision.


      Johnson sought judicial review of the Commissioner’s final decision. On
September 15, 2003, a magistrate judge affirmed the Commissioner’s administrative
decision. Johnson appeals that decision.


                                         II.


      We review de novo the district court’s decision to uphold the denial of social
security benefits. Pettit v. Apfel, 

, 902 (8th Cir. 2000). “Our review
of the Commissioner’s decision . . . is deferential, and we do not substitute our own
view of the evidence for that of the Commissioner.” Kelley v. Barnhart, 

, 960 (8th Cir. 2004). We review the decision to ensure that it “is supported by

                                         -4-
substantial evidence in the record as a whole.” Gaddis v. Chater, 

, 895
(8th Cir. 1996); see also Dixon v. Barnhart, 

, 604 (8th Cir. 2003).
Substantial evidence is evidence that a reasonable mind would find adequate to
support a decision, considering both evidence that detracts from and evidence that
supports the Commissioner’s decision. Young v. Apfel, 

, 1068 (8th
Cir. 2000). The mere fact that some evidence may support a conclusion opposite to
that reached by the Commissioner does not allow this Court to reverse the decision
of the ALJ. Gaddis v. Chater, 

, 895 (8th Cir. 1996). “If, after review,
we find it possible to draw two inconsistent positions from the evidence and one of
those positions represents the Commissioner’s findings, we must affirm the decision
of the Commissioner.” Nguyen v. Chater, 

, 431 (8th Cir. 1996).


       In evaluating disability claims, we conduct a five-step sequential evaluation:
1) is the claimant engaging in substantial gainful activity; 2) does the claimant have
severe impairment(s); (3) does the impairment or combination of impairments meet
or equal an impairment listed in the listing of impairments in 20 C.F.R. Part 404,
Appendix 1, Subpart P (2003); 4) does the impairment or combination of
impairments prevent the claimant from doing past relevant work; and 5) does the
impairment or combination of impairments prevent the claimant from doing any
other work which exists in significant numbers in the national economy. 20 C.F.R.
§ 404.1520(a)-(f) (2003). In this case, the ALJ concluded at the third step that Mr.
Johnson’s impairments do not meet or equal an impairment in the listings. The ALJ
went on to conclude at step four that Johnson’s limitations do not preclude him from
returning to past relevant work. We conclude that these findings are supported by
substantial evidence.


      Appellant argues that the ALJ committed an error at step three by not finding
that Johnson did not meet or equal a listed impairment. The burden of proof is on
the plaintiff to establish that his or her impairment meets or equals a listing. See

                                         -5-
Sullivan v. Zebley, 

, 530-31 (1990). To meet a listing, an impairment
must meet all of the listing’s specified criteria. 

(“An impairment that
manifests only some of these criteria, no matter how severely, does not qualify.”).
“Medical equivalence must be based on medical findings.” 20 C.F.R. § 416.926(b)
(2003); 

(“a claimant . . . must present medical findings
equal in severity to all the criteria for the one most similar listed impairment”).


       The specified criteria for 20 C.F.R. Pt. 404, Subpt. P, App. 1, § 12.05 B and C
regarding mental retardation are as follows. A person must have “significantly
subaverage general intellectual functioning with deficits in adaptive functioning
initially manifested during the developmental period; i.e., . . . before age 22.” Level
of intellectual functioning requirements are satisfied by evidence of “[a] valid verbal,
performance, or full scale IQ of 59 or less” or “[a] valid verbal, performance, or full
scale IQ of 60 through 70 and a physical or other mental impairment imposing an
additional and significant work-related limitation of function[.]” 20 C.F.R. Pt. 404,
Subpt. P, App. 1, § 12.05 B and C.


      Johnson claims that psychological testing performed in 1998 and 2001 by Dr.
Richard Maddock demonstrates that he meets the listing for mental retardation since
it showed mild mental retardation and a low IQ. The SSA counters that the 1998 and
2001 tests Johnson points to fail to provide evidence that his impairments meet the
criteria of § 12.05 B or C, since Dr. Maddock stated that his tests were unreliable on
account of malingering by Johnson. The ALJ concluded that Johnson was not under
a disability within the meaning of the Social Security Act at any time through the
date of its decision.


     The ALJ’s conclusion is supported by substantial evidence in the record.
Principally, the ALJ discounted the results of both psychological evaluations on


                                          -6-
which Johnson relied due to evidence that Johnson malingered during the
examinations and due to the fact that the ALJ failed to find evidence of a lack of
adaptive functioning by Johnson.


      While an IQ test is helpful in determining whether an applicant has a mental
impairment, it is not the only evidence that may be examined. Other information
which indicates an individual’s ability to function can be used to discredit the results
of the IQ test. Holland v. Apfel, 

, 622 (8th Cir. 1998). We have held
that an ALJ may reject IQ scores if they are inconsistent with the rest of the record.
Clark v. Apfel, 

, 1255 (8th Cir. 1998). Test results should be
examined to assess consistency with daily activities. 

case, the ALJ
appropriately took into consideration Dr. Maddock’s conclusions that Johnson
malingered and that Johnson did not display the significant limitations in adaptive
functioning that 12.05 requires.


      In his first report from 1998, Dr. Maddock stated that Johnson’s Wahler
Physical Symptoms Inventory score showed strong indications of malingering and
that Johnson answered items on the Minnesota Multiphasic Personality Inventory-2
randomly. Dr. Maddock’s September 2001 report also noted that Johnson’s behavior
showed indications that he answered randomly to many items without regard to
content. Dr. Maddock concluded that little or no weight should be given to the
information. The Computerized Assessment of Response Bias verified malingering
and response bias. Dr. Maddox stated that Johnson “wanted to receive or continue
benefits[,] and [that Johnson] felt the best way to do that would be to embellish or
exaggerate a disability,” and that Johnson was not open and honest during his
interview. Finally, the Weschler Memory Scale-Revised presented scores
inconsistent with other test scores and with Johnson’s complaints of a poor memory
(they showed a strong memory).



                                          -7-
      The record also indicates that Johnson did not display the significant
limitations in adaptive functioning that 12.05 requires. 20 C.F.R. Pt. 404, Subpt. P,
App. 1, § 12.05 B and C. In fact, the district court stated in its review that
“[Johnson] testified that he would still be working at the time of the hearing had he
not been fired[,]” and “that he was looking for work at the time of the hearing.”


      Thus, ample evidence exists in the record to support the conclusion of the ALJ.
Johnson failed to meet his burden of proof in demonstrating that he meets the
requirements of 12.05 because: 1) he failed to provide a valid IQ test due to
continual malingering; and 2) his ability to function despite a possible limited IQ.
Accordingly, the Social Security Administration’s determination was reasonable.


     The judgment of the district court is affirmed.
