      Marcia Jackson appeals from the district court’s grant of summary judgment in

favor of her former employer, Kansas City Kansas Public Schools Unified School

District No. 500 (“USD 500”), on her harassment, retaliation, and discrimination

claims. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.




      *
        After examining the briefs and appellate record, this panel has determined
unanimously that oral argument would not materially assist in the determination of
this appeal. See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore
ordered submitted without oral argument. This order and judgment is not binding
precedent, except under the doctrines of law of the case, res judicata, and collateral
estoppel. It may be cited, however, for its persuasive value consistent with
Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
                                           I

      Jackson started working for USD 500 in 2016. She alleges that in September

2016, she was routinely sexually harassed by her co-worker, Eugene Swygert, but she

did not report his conduct to USD 500. Beginning in October 2016, Jackson’s co-

worker Keyannah Johnson bullied and threatened her. Jackson alleges she filed a

complaint about Johnson’s conduct with Lenora Miller, USD 500’s Executive

Director of Operations, but Miller took no corrective action. Jackson claims

Johnson’s harassment later became sexual—Johnson would rub her body against

Jackson—but Jackson admits the October 2016 complaint did not address any alleged

sexual misconduct by either Swygert or Johnson.

      In December 2016, Swygert and Jackson had a verbal altercation. According

to Jackson’s affidavit about the incident, Swygert became angry, made “embarrassing

comments” about Jackson’s looks, called her ugly, made statements about her body

parts, and made a vulgar sexual comment. This occurred on the day before the

school district’s winter break began. Jackson reported the incident to Miller the next

day. After winter break, Miller placed Swygert on administrative leave pending

further investigation into Jackson’s allegations. Jackson met with Miller and filed a

written sexual harassment complaint against Swygert. Jackson also expressed

concerns for her safety, and Miller placed Jackson on paid administrative leave.

      During Miller’s investigation, she obtained written statements from four

employees, including Johnson, who witnessed the December exchange between

Jackson and Swygert. Johnson’s statement indicated that Jackson had become upset

                                          2
and called Swygert a “[b]astard” and “ignorant.” Miller determined that both

Swygert and Jackson had engaged in inappropriate conduct in violation of policies

established by USD 500’s Board of Education (“District Policies”), and she

recommended the Board terminate their employment.

      Miller then informed Jackson of her alleged violations of District Policies.

Jackson denied the violations and told Miller she thought the investigation was a

“witch hunt.” At the close of her investigation, Miller sent Jackson a letter stating

her conclusion that Jackson violated District Policies prohibiting: (1) the use of

profanity or abusive language; (2) conduct that is “detrimental to [USD 500]

personnel” and that could cause undue disruption of work or endanger the safety of

others; and (3) conduct that constitutes workplace violence. Miller explained that

employees who violate District Policies are “subject to disciplinary action, . . .

including termination.” She further advised Jackson that pursuant to District

Policies, she would be given “an opportunity to present [her] side of the story” at a

hearing, consistent with Cleveland Bd. of Educ. v. Loudermill, 

(1985).

Jackson initially agreed to attend a Loudermill hearing, but later refused to do so.

The Board ultimately approved Miller’s recommendation to terminate both Swygert

and Jackson.

      Jackson filed suit, alleging that USD 500 violated Title VII of the Civil Rights

Act of 1964 (“Title VII”), 42 U.S.C. § 2000e-2, by creating a sexually hostile work

environment and terminating her in retaliation for reporting Johnson’s sexual

harassment. She also alleged USD 500 terminated her based on her age—she was 64

                                            3
years old—in violation of the Age Discrimination in Employment Act, 29 U.S.C.

§ 623(a)(1). The court granted summary judgment in favor of USD 500 on all

claims. Jackson timely appealed.

                                           II

      Because Jackson is proceeding pro se, we construe her pleadings liberally, see

Ledbetter v. City of Topeka, 

, 1187 (10th Cir. 2003), but do not “take

on the responsibility of serving as [her] attorney in constructing arguments and

searching the record,” Garrett v. Selby Connor Maddux & Janer, 

, 840

(10th Cir. 2005). Jackson contends the district court should have stricken Johnson’s

written witness statement describing the December 2016 incident, which was

attached to the affidavit of Susan Westfahl, USD 500’s custodian of records. “[I]t is

well settled in this circuit that we can consider only admissible evidence in reviewing

an order granting summary judgment.” Law Co. v. Mohawk Constr. & Supply Co.,

, 1170 (10th Cir. 2009) (quotation omitted). We review a district

court’s evidentiary rulings at the summary judgment stage for abuse of discretion.

Sports Racing Servs., Inc. v. Sports Car Club of Am., Inc., 

, 894 (10th

Cir. 1997). We will not disturb the district court’s ruling unless we have a “definite

and firm conviction” that the court “made a clear error of judgment or exceeded the

bounds of permissible choice in the circumstances.” Lantec, Inc. v. Novell, Inc., 

, 1016 (10th Cir. 2002) (quotation omitted).

      At the district court, Jackson moved to strike Johnson’s statement, arguing that

USD 500 did not timely produce or properly authenticate it. The court concluded

                                           4
USD 500 had met its duty to disclose under Fed. R. Civ. P. 26(a) because its initial

disclosures sufficiently identified the statement. With respect to authentication, the

court concluded that although Westfahl’s affidavit failed to establish that Johnson’s

statement was self-authenticating under Fed. R. Evid. 902, an affidavit by Miller was

sufficient to authenticate the statement under Fed. R. Evid. 901(a). As a result, the

district court denied Jackson’s motion to strike.

      We conclude that the district court did not abuse its discretion in admitting

Johnson’s statement. Although USD 500’s initial disclosures, parts of which Jackson

filed on the record in connection with her motion to strike, did not specifically list

the statement, they do list “Witness statements relating to December 20, 2016

incident.” We also conclude Johnson’s statement was properly authenticated.

Although “[w]e do not require an affidavit to authenticate every document submitted

for consideration at summary judgment,” Law 

, there was an

affidavit from Miller authenticating Johnson’s statement. To authenticate Johnson’s

statement, USD 500 was required to produce evidence that the statement was what

USD 500 claimed it was. See Fed. R. Evid. 901(a). “[T]he bar for authentication of

evidence is not particularly high.” United States v. Isabella, 

, 843 (10th

Cir. 2019) (quotation omitted). In assessing authenticity, we ask “whether there is a

reasonable probability that the evidence has not been altered in any material aspect.”

Miller’s affidavit stated that as part of her investigation of

the December 2016 incident, she obtained a statement from Johnson. And Miller

certified based on her personal knowledge that a true and correct copy of Johnson’s

                                            5
statement was attached to Westfahl’s affidavit. We hold the district court did not

abuse its discretion in determining that Johnson’s statement was admissible.1

      Jackson also contends the district court abused its discretion when it refused to

consider a statement by Shannon Rinehart because the statement did not “appear in a

conforming affidavit or declaration.” Jackson v. Kan. City Kan. Pub. Sch. Unified

Sch. Dist. No. 500, 

, 1029 n.8 (D. Kan. 2019). We agree. The

district court did not address whether the statement was authenticated by any other

means. See Law 

-71 (holding a district court may not

“summarily disregard[]” or “categorically discard[]” unauthenticated exhibits, but

rather must consider their “appearance, contents, substance, internal patterns, or other

distinctive characteristics”). The district court should have considered whether

Rinehart’s statement was otherwise authenticated. But any error is harmless. The

district court considered Jackson’s affidavit, which included the same content as

Rinehart’s excluded statement.2

                                           III

      Turning to Jackson’s challenge to the district court’s summary judgment

ruling, we review the district court’s grant of summary judgment de novo. See



      1
      Jackson also argues Johnson’s statement was false and unsworn. This
argument goes to the statement’s reliability, not its admissibility. See 

      2
         Further, Rinehart’s statement was about the content of Swygert’s sexually
inappropriate comments to Jackson in December 2016. The district court, construing
the facts in the light most favorable to Jackson, assumed for purposes of its analysis
that Swygert made the inappropriate comments.
                                            6
Young v. Dillon Cos., 

, 1249 (10th Cir. 2006). Summary judgment is

appropriate if “the movant shows that there is no genuine dispute as to any material

fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a).

We view all of the facts in the light most favorable to the non-moving party and draw

all reasonable inferences in her favor. DeWitt v. Sw. Bell Tel. Co., 

,

1306 (10th Cir. 2017).

                                          A

      We first address Jackson’s hostile work environment claim. “To establish that

a sexually hostile work environment existed, a plaintiff must prove the following

elements: (1) she is a member of a protected group; (2) she was subject to

unwelcome harassment; (3) the harassment was based on sex; and (4) due to the

harassment’s severity or pervasiveness, the harassment altered a term, condition, or

privilege of the plaintiff’s employment and created an abusive working

environment.” Harsco Corp. v. Renner, 

, 1186 (10th Cir. 2007)

(alteration and quotation omitted). If a sexually hostile work environment claim is

based on the employer’s alleged negligence or recklessness in addressing a non-

supervisory co-worker’s harassment, the plaintiff must also prove that the employer

“had actual or constructive knowledge of the hostile work environment but did not

adequately respond to notice of the harassment.” 

summary judgment, the plaintiff has the burden of presenting

evidence establishing a genuine issue of fact that her employer knew about the sexual

harassment and that its response was unreasonable. See Ford v. West, 

,

                                           7
776 (10th Cir. 2000). A plaintiff can show actual knowledge by showing she

“reported harassment to management-level employees” and can show constructive

knowledge if “the pervasiveness of sexual harassment can properly lead to an

inference of knowledge.” Adler v. Wal-Mart Stores, Inc., 

, 673 (10th

Cir. 1998). To show that the employer’s response was inadequate, the plaintiff must

show that it was not “reasonably calculated to end the harassment.” 

(quotation omitted).

      Jackson’s hostile work environment claim is based on Swygert’s September

2016 conduct, Johnson’s sexually inappropriate behavior, and the sexually offensive

comments Swygert made to Jackson in December 2016. Although Jackson reported

Johnson’s bullying behavior to Miller in October 2016, she did not suggest that the

bullying was sexual. Jackson also did not report Johnson’s subsequent sexual

misconduct or Swygert’s September 2016 sexually inappropriate behavior to any

management-level employee until after her December 2016 altercation with Swygert.

      We thus conclude USD 500 did not have actual or constructive knowledge of

the sexual misconduct until December 2016. The October 2016 complaint was

insufficient to give USD 500 actual knowledge of sexual harassment because Jackson

did not tell Miller the bullying was sexual. As for constructive knowledge, Johnson

has not alleged facts sufficient to demonstrate the incidents of harassment were “so

egregious, numerous, and concentrated as to add up to a campaign of harassment”

that put USD 500 on notice of the harassment before December 2016. Baker v.



                                          8
Weyerhaeuser Co., 

, 1346 (10th Cir. 1990) (quotation omitted); see

also Kramer v. Wasatch Cty. Sheriff’s Office, 

, 757 (10th Cir. 2014).

      We also conclude that USD 500 responded reasonably to Jackson’s December

2016 report of harassment. To assess the reasonableness of an employer’s response,

we ask “whether the remedial and preventative action was reasonably calculated to

end the harassment.” 

(quotation omitted). “Plaintiff bears the

burden of presenting evidence establishing a genuine issue of fact that the employer’s

response was unreasonable.” 

. USD 500 placed Swygert on

administrative leave immediately after winter break, placed Jackson on

administrative leave to prevent further victimization, and ultimately fired Swygert.

As a result of USD 500’s remedial actions, Swygert’s harassment immediately

stopped. USD 500’s response was thus reasonably calculated to end the harassment.

See 

(“A stoppage of harassment shows effectiveness, which in

turn evidences such reasonable calculation.”).

                                           B

      Turning to the retaliation claim, because Jackson presented no direct evidence

of retaliation, we analyze her claim under the three-step burden-shifting framework

set forth in McDonnell Douglas Corp. v. Green, 

, 802-04 (1973). See

Khalik v. United Air Lines, 

, 1192 (10th Cir. 2012). A plaintiff carries

the initial burden of establishing a prima facie case by showing: “(1) she engaged in

protected opposition to discrimination; (2) she suffered an adverse action that a

reasonable employee would have found material; and (3) there is a causal nexus

                                           9
between her opposition and the employer’s adverse action.” Johnson v. Weld Cty.,

, 1215 (10th Cir. 2010) (quotation omitted). The burden then “shifts to

the employer to offer a legitimate nondiscriminatory reason for its employment

decision.” Morgan v. Hilti, Inc., 

, 1323 (10th Cir. 1997). If the

employer makes that showing, the burden shifts back to the plaintiff “to show that

there is a genuine dispute of material fact as to whether the employer’s proffered

reason for the challenged action is pretextual.” 

      The district court assumed for purposes of the summary judgment motion that

Jackson had established a prima facie case of retaliation. We do the same.3 The

court ultimately granted summary judgment because it concluded Jackson failed to

show pretext. To show USD 500’s proffered nondiscriminatory explanation for

firing her was pretextual, Jackson must establish that the explanation is “so

incoherent, weak, inconsistent, or contradictory that a rational factfinder could

conclude [it is] unworthy of belief.” 

(alteration and

quotation omitted). We do not “ask whether the employer’s decision was wise, fair

or correct, but whether [the employer] honestly believed the legitimate,




      3
         USD 500 challenges this assumption on appeal. We do not need to resolve
this issue because we ultimately conclude the district court properly granted summary
judgment based on Jackson’s failure to show pretext. See Chen v. Dow Chem. Co.,

, 402 (6th Cir. 2009) (court need not address prima facie case where
plaintiff failed to create a genuine issue of material fact as to pretext); Olsen v.
Marshall & Ilsley Corp., 

, 600 (7th Cir. 2001) (same).

                                           10
nondiscriminatory reasons it gave for its conduct and acted in good faith on those

beliefs.” 

quotation omitted).

       USD 500 stated it terminated Jackson because by calling Swygert a “bastard”

and “ignorant,” she violated District Policies prohibiting profanity or abusive

language, conduct detrimental to other personnel that could cause undue disruption or

endanger others’ safety, and workplace violence. Jackson argues that these reasons

were pretextual because USD 500 did not follow its own termination policies. To the

contrary, the district court concluded that USD 500 followed its internal policies by

giving Jackson a written explanation of the reasons for her termination and offering

her a Loudermill hearing. Ultimately, the district court concluded Miller’s

recommendation to terminate Jackson was based on a good faith belief that she had

violated District Policies.

       Jackson does not take issue with this determination on appeal. Instead, as we

understand her argument, she contends USD 500’s proffered reason for terminating

her was pretextual because Miller told her she was being terminated based on her

“poor work performance” and Miller should not have relied on Johnson’s description

of Jackson’s behavior as the basis for her termination recommendation. Neither of

these arguments establishes that USD 500’s stated reason for firing Jackson—her

violation of District Policies—was “unworthy of belief.” 

Accordingly, we conclude the district court did not err in granting summary judgment

on this claim.



                                           11
                                          C

      Jackson raised an age discrimination claim in her complaint, but the district

court held the claim was abandoned because Jackson did not include it in the pretrial

order. See Hullman v. Bd. of Trs. of Pratt Cmty. Coll., 

, 667 (10th Cir.

1991) (“The pretrial order supersedes the pleadings and controls the subsequent

course of litigation.”). Jackson does not dispute that the age discrimination claim

was omitted from the pretrial order. Accordingly, we conclude that Jackson

abandoned her age discrimination claim.
