RICHARDSON, Circuit Judge:

       Dr. Zoe Spencer, a sociology professor at Virginia State University, sued the

University under the Equal Pay Act and Title VII for paying her less than two male

professors, allegedly because she is a woman.

       Spencer earned about $70,000 per year—a median salary when compared to the

men who were also full professors in the Department of Sociology, Social Work, and

Criminal Justice. But Spencer’s lawsuit proposes comparing her pay to that of two

former University administrators, Drs. Michael Shackleford and Cortez Dial, who each

earned over $100,000 per year as professors in other departments. While Spencer asserts

that the difference in pay was due to her sex, the University provides a different

explanation:   Shackleford’s and Dial’s jobs differed from Spencer’s and, as former

administrators, their pay was set as a prorated portion of their previous salaries.

       After discovery, the district court granted summary judgment for the University

(and its former president, Dr. Keith Miller). We affirm. Though Spencer establishes a

pay disparity, she fails to present evidence that creates a genuine issue of material fact

that Shackleford and Dial are appropriate comparators. In any event, unrebutted evidence

shows that the University based Shackleford’s and Dial’s higher pay on their prior

service as University administrators, not their sex. 1

light most favorable to the nonmovant, summary judgment is appropriate “if the movant
shows that there is no genuine dispute as to any material fact.” Fed. R. Civ. P. 56(a).

                                 I.     Equal Pay Act

      Spencer first claims that the disparity between her salary and her chosen

comparators’ violates the Equal Pay Act. The statute forbids the University (like other

employers) from:

      Discriminat[ing] . . . between employees on the basis of sex by paying
      wages to employees . . . at a rate less than the rate at which [the employer]
      pays wages to employees of the opposite sex . . . for equal work on jobs the
      performance of which requires equal skill, effort, and responsibility, and
      which are performed under similar working conditions, except where such
      payment is made pursuant to (i) a seniority system; (ii) a merit system; (iii)
      a system which measures earnings by quantity or quality of production; or
      (iv) a differential based on any other factor other than sex . . . .

29 U.S.C. § 206(d)(1). To prove a violation of the Act, Spencer must make an initial

(i.e., prima facie) showing of three elements: (1) the University paid higher wages to an

employee of the opposite sex who (2) performed equal work on jobs requiring equal skill,

effort, and responsibility (3) under similar working conditions. EEOC v. Maryland Ins.

Admin., 879 F.3d 114, 120 (4th Cir. 2018) (citing Corning Glass Works v. Brennan, 417

U.S. 188, 195 (1974)).

      This initial showing permits an inference that a pay disparity was based on sex

discrimination. Maryland Ins. Admin., 879 F.3d at 120. The inference of discrimination

stands even without the support of any evidence of discriminatory intent. Id. Only once




“To survive summary judgment, ‘there must be evidence on which the jury could
reasonably find for the nonmovant.’” Lee v. Town of Seaboard, 863 F.3d 323, 327 (4th
Cir. 2017) (quoting Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 252 (1986)).


                                            3
this inference exists does the burden shift to the employer to show that the pay

differential was based on a factor other than sex. Id.

         Spencer’s choice of Shackleford and Dial as comparators establishes the first

element of her initial showing—the existence of a wage differential. By choosing two of

the highest-paid professors at the University, Spencer ensured that her wages were much

lower.     Yet that same decision to pick Shackleford and Dial precludes her from

establishing, as the second element requires, that she and they performed “equal” work

requiring “equal skill, effort, and responsibility.”

         Equality under the Act is a demanding threshold requirement.        It requires a

comparator to have performed work “virtually identical” (or the apparent synonym,

“substantially equal”) to the plaintiff’s in skill, effort, and responsibility. Wheatley v.

Wicomico Cty., 390 F.3d 328, 332–33 (4th Cir. 2004). Similarity of work is not enough;

the Act explicitly distinguishes between the work itself (which must be “equal”) and the

conditions of work (which need only be “similar”). 29 U.S.C. § 206(d)(1). The Act does

not provide courts with a way of evaluating whether distinct work might have

“comparable” value to the work the plaintiff performed. See Wheatley, 390 F.3d at 333;

see also Sims-Fingers v. City of Indianapolis, 493 F.3d 768, 771 (7th Cir. 2007) (Posner,

J.) (explaining that, when trying to identify “comparable” pay for unequal work, there are

“no good answers that are within the competence of judges to give”). Instead, the Act’s

inference of discrimination may arise only when the comparator’s work is equal to the

plaintiff’s.



                                               4
         In alleging this necessary equality, a plaintiff may not rely on broad

generalizations at a high level of abstraction. Wheatley, 390 F.3d at 332. But Spencer

attempts just such an impermissibly general comparison.           In Spencer’s view, all

University professors perform equal work because they all perform the same essential

tasks:    preparing syllabi and lessons, instructing students, tracking student progress,

managing the classroom, providing feedback, and inputting grades. See Appellant’s Brief

at 9. The performance of these tasks, Spencer posits, requires the same skills: studying,

preparing, presenting, discussing, and so forth. See id. at 9–10. But these tasks and skills

are shared by middle-school teachers and law-school professors, pre-algebra teachers and

biomedical-engineering professors.

         This attempted comparison ultimately relies on the common title of “professor”

plus some generalized responsibilities (e.g., teaching students). Yet we have rejected an

analogous claim that jobs with the same title and only vaguely corresponding

responsibilities can be considered equal. In Wheatley we concluded that the plaintiffs,

supervisors in a county’s emergency-services department, failed to meet their burden to

show that supervisors in different departments performed equal work because they could

not demonstrate that the different jobs were equal in skill and responsibility. 390 F.3d at

334; see also Sims-Fingers, 493 F.3d at 771. Spencer’s case suffers from a near-identical

flaw.

         Spencer’s bird’s-eye view is particularly unpersuasive given the inherent features

of academia. Professors are not interchangeable like widgets. Various considerations

influence the hiring, promotion, and compensation of different professorial jobs. Cf.

                                             5
Zahorik v. Cornell Univ., 729 F.2d 85, 93 (2d Cir. 1984) (discussing the tenure process).

As a result, faculty salary decisions require a complex balancing of factors. Among other

things, those decisions account for the differences in skill and responsibility attendant to

different jobs. For instance, an engineering professorship requires different skills, effort,

and responsibility than professorships in other fields, such as sociology.         Evidence

offered by Spencer proves this very point:           The University systematically pays

engineering professors more than humanities professors. J.A. at 136. This reflects

differences in skill along with market forces that compensate engineers more highly.

This market reality confirms that Spencer’s broad generalizations about tasks and skills,

which apply to virtually all teachers, fail to satisfy her burden to show equal work.

       In contrast to Spencer’s generalized tasks and skills, a litany of concrete

differences underscore that Spencer does not perform work equal to that of Shackleford

and Dial. First, Shackleford and Dial taught in different departments than Spencer did.

While comparisons might be drawn between some departments, any such comparison

requires the plaintiff to articulate with specificity why the work performed and skills

needed by a professor in one department are virtually identical—and not just generally

related or of comparable worth—to those in another. As our precedents recognize, the

differences between academic departments generally involve differences in skill and

responsibility. See Strag v. Bd. of Trustees, Craven Cmty. Coll., 55 F.3d 943, 950 (4th

Cir. 1995) (finding that the Biology and Mathematics departments required instructors to

have different skills and responsibilities); Soble v. Univ. of Maryland, 778 F.2d 164, 167

(4th Cir. 1985) (finding that the specialized nature of certain university departments

                                             6
called for distinct skills); cf. Wheatley, 390 F.3d at 332–33 (recognizing job-related

differences for directors of different county government departments).

       There are still more differences. Along with serving in different departments, the

three professors taught at different class levels at the University. Spencer taught mainly

undergraduate courses, while Shackleford and Dial taught more graduate courses. And

Shackleford also supervised doctoral dissertations. Contrary to Spencer’s assertion, the

fact that the University credited hours spent supervising dissertations in a similar manner

to hours spent teaching regular courses does nothing to establish the equivalency of

supervising dissertations and teaching undergraduates. Nor did the professors work equal

hours, as the record shows that Shackleford and Dial worked more than Spencer did week

to week. 2

       None of this is to say that the Equal Pay Act cannot apply in the higher-education

context. But in that context—one where the work is an exercise in intellectual creativity

that can be judged only according to intricate, field-specific, and often subjective

criteria—Spencer must provide the court with more than broad generalities to meet her

burden. She must present evidence on which a jury could rely to decide that she,

Shackleford, and Dial had equal jobs, not just that they all performed vaguely related


       2
         Spencer paradoxically argues that other differences between her work and that of
her chosen comparators render her work equal. For example, Spencer asserts that she
conducted research and published while Shackleford and Dial did not. This evidence
cannot save her claim given the differences already discussed. Piling on differences—
even those suggesting that Spencer did better or more work—does nothing to prove
equality of work.


                                            7
tasks using nominally comparable skills. That is, there must be evidence showing the

jobs were equal in the strict sense of involving “virtually identical” work, skill, effort,

and responsibility, not in the loose sense of having some comparative value. Wheatley,

390 F.3d at 333.

       Despite all of these issues, Spencer claims her expert, Joseph Rosenberg, found

“that Shackleford and Dial were significantly overpaid in comparison to Spencer.”

Appellant’s Brief at 44 (emphasis added). Not only is this irrelevant to establishing equal

work, this claim is a bit misleading: Rosenberg asserted that Shackleford and Dial were

overpaid relative to all other professors, both men and women. 3

       In addition to looking at her chosen comparators, Spencer’s expert tried to identify

a general disparity between the pay of men and women at the University. But his efforts

       3
           Spencer’s brief asserts that Rosenberg:
       used four independent variables to account for the skill, effort, and
       responsibility required of professors at [the University], taking into account
       experience, departmental affiliation, faculty rank, and whether the professor
       was a Chair or Dean. Rosenberg found, at a 97.5% confidence interval,
       that Shackleford and Dial were significantly overpaid in comparison to
       Spencer even when accounting for the different departments in which they
       taught.

Appellant’s Brief at 44 (citations and emphasis omitted). Contrary to Spencer’s
characterization, Rosenberg’s report does not appear to take departmental affiliation into
account, instead only accounting for the broader category of “school,” each of which
encompasses several departments. And there is another flaw, though immaterial given
the report’s other shortcomings: Rosenberg’s expert report does not account for
Spencer’s comparators’ prior work in the administration, even though everyone appears
to agree that their prior administrative experience determined their salaries. Cf. Smith v.
Virginia Commonwealth Univ., 84 F.3d 672, 675 (4th Cir. 1996) (noting that
administrators are generally paid higher salaries than teachers and that these higher
salaries persist when administrators move back to teaching).

                                               8
revealed no statistically significant disparity within each “school.” If anything, this

evidence undermines Spencer’s claimed inference of discrimination. See Strag, 55 F.3d

at 950 (suggesting that “isolated incidents or random comparisons demonstrating

disparities in treatment may be insufficient to draw a prima facie inference of

discrimination without additional evidence that the alleged phenomenon of inequality

also exists with respect to the entire relevant group of employees” (quoting Houck v.

Virginia Polytechnic Ins., 10 F.3d 204, 206–07 (4th Cir. 1993)).

       Despite her expert’s efforts, Spencer’s generalized claims cannot establish that she

engaged in equal work, which categorically dooms her attempt to establish wage

discrimination under the Equal Pay Act. Cf. Wheatley, 390 F.3d at 334 (a plaintiff may

not “indiscriminately aim at all department supervisors collectively, and then expect to

meet the EPA standard” for equal work).

       But even if Spencer could meet her initial burden, her claim would still fail

because the University established that the salary difference was based on a “factor other

than sex.” 29 U.S.C. § 206(d)(1)(iv). As the defendant, the University bore the burden

of establishing this affirmative defense.     Maryland Ins. Admin., 879 F.3d at 120.

Granting summary judgment on this ground required the district court to find that the

proffered reason did in fact explain the wage disparity, not merely that it could. Id. at

121.

       Here, there is no dispute that the wage difference at issue resulted from the

University setting Shackleford’s and Dial’s pay at 75% of their previous salaries as

administrators. In practice, the University generally paid former administrators who

                                            9
became professors “9/12ths” of their administrator salary. This practice appears to rest

on the theory that professors work nine months out of the year, while administrators work

year-round. Indeed, Spencer admits that her comparators’ pay during their short stints as

University professors was set according to the 9/12ths practice. Appellant’s Reply Brief

at 16 (“Shackleford and Dial’s salaries were set entirely on their prior salaries as

administrators.”).

       In response to the University’s explanation, Spencer claims that the 9/12ths

practice should not have been used to calculate Shackleford’s and Dial’s salaries.

According to her, the University’s historical practice only applied to administrators who

were previously tenured faculty. But even if the University erroneously applied its

9/12ths practice to overpay Shackleford and Dial, such an imprudent decision would still

serve as a non-sex-based explanation for the pay disparity.           See Anderson v.

Westinghouse Savannah River Co., 406 F.3d 248, 272 (4th Cir. 2005) (“We do not sit as

a ‘super-personnel department weighing the prudence of employment decisions’ made by

the defendants.” (quoting DeJarnette v. Corning, Inc., 133 F.3d 293, 299 (4th Cir.

1998)); Smith v. Univ. of North Carolina, 632 F.2d 316, 346 (4th Cir. 1980) (“[The] law

does not require, in the first instance, that employment be rational, wise, or well-

considered—only that it be nondiscriminatory.” (quoting Powell v. Syracuse Univ., 580

F.2d 1150, 1156–57 (2d Cir. 1978)).

       The Equal Pay Act is a powerful tool, permitting an employee to prevail on a wage

discrimination claim with no evidence of intentional discrimination. But this tool must

be tempered by adherence to its provisions. Doing so requires that the work performed

                                           10
by the plaintiff and her comparators be equal and that the wage disparity not be based on

a factor other than sex. Spencer’s claim fails on both requirements.

                                     II.    Title VII

       Having rejected Spencer’s Equal Pay Act claim, we must separately consider her

claim of Title VII sex-based wage discrimination. Under Title VII of the Civil Rights

Act of 1964, an employer cannot “discriminate against any individual with respect to

[her] compensation . . . because of such individual’s . . . sex.” 42 U.S.C. § 2000e-2(a)(1).

Title VII, in contrast to the Equal Pay Act, requires establishing intentional

discrimination. A Title VII plaintiff may make this showing of intentional discrimination

using direct or circumstantial evidence. Alternatively, the plaintiff may use the burden-

shifting framework of McDonnell Douglas Corp. v. Green, 411 U.S. 792 (1973), “to

develop an inferential case” of discriminatory intent.        Chalmers v. Tulon Co. of

Richmond, 101 F.3d 1012, 1017 (4th Cir. 1996).

       A prima facie pay-disparity case under McDonnell Douglas requires a plaintiff to

establish (1) she is a member of a protected class, (2) she was performing her job

satisfactorily, (3) an adverse employment action occurred, and (4) the circumstances

suggest an unlawfully discriminatory motive. See McDonnell Douglas, 411 U.S. at 802;

Texas Dep’t of Cmty. Affairs v. Burdine, 450 U.S. 248, 253 (1981). Where, as here, the

prima facie case of wage discrimination is based on comparators, the plaintiff must show

that she is paid less than men in similar jobs. See Brinkley-Obu v. Hughes Training, Inc.,

36 F.3d 336, 343 (4th Cir. 1994).



                                            11
       Title VII requires the compared jobs to be only “similar” rather than “equal,” as

required under the Equal Pay Act. See id. While there is no bright-line rule for what

makes two jobs “similar” under Title VII, courts consider “whether the employees (i)

held the same job description, (ii) were subject to the same standards, (iii) were

subordinate to the same supervisor, and (iv) had comparable experience, education, and

other qualifications—provided the employer considered these latter factors in making the

personnel decision.” Bio v. Fed. Express Corp., 424 F.3d 593, 597 (7th Cir. 2005)

(internal quotation marks omitted); see also Herster v. Bd. of Supervisors of Louisiana

State Univ., 887 F.3d 177, 185 (5th Cir. 2018) (stating that a “variety of factors are

considered when determining whether a comparator is similarly situated, including job

responsibility, experience, and qualifications.”).      While Title VII’s “similarity”

requirement demands less of plaintiffs than the Equal Pay Act’s “equality” requirement,

it is not toothless: the plaintiff must provide evidence that the proposed comparators are

not just similar in some respects, but “similarly-situated in all respects.” Mitchell v.

Toledo Hosp., 964 F.2d 577, 583 (6th Cir. 1992). For the same reasons we discussed

above, Spencer’s broad generalizations cannot even show sufficient similarity to meet her

burden under Title VII. 4




       4
         Just as in the Equal Pay Act context, Spencer’s expert does not help her to
establish a prima facie case here. While a plaintiff may use statistics to suggest a
discriminatory motive, Spencer’s expert found no statistical evidence that the University
paid women less than men.


                                           12
       Even if we concluded that Spencer had established a prima facie case of Title VII

wage discrimination, her case still could not withstand summary judgment. Once a

plaintiff establishes a prima facie case, the burden of production shifts to the employer to

proffer a legitimate, nondiscriminatory explanation for the wage disparity. Guessous v.

Fairview Prop. Investments, LLC, 828 F.3d 208, 216–17 (4th Cir. 2016); Maryland Ins.

Admin., 879 F.3d at 120 n.7. Here, the University satisfies this requirement through its

practice of paying administrators 9/12ths of their previous salary. Just as this practice

satisfies the Equal Pay Act’s “factor other than sex” affirmative defense, it qualifies as a

legitimate, nondiscriminatory explanation under Title VII. Cf. Cty. of Washington v.

Gunther, 452 U.S. 161, 169 (1981) (recognizing that the Bennett Amendment to Title VII

incorporates the four affirmative defenses from the Equal Pay Act).

       Having proffered a nondiscriminatory explanation, the University shifts the burden

back to Spencer to prove that the explanation is merely pretextual for invidious

discrimination. Guessous, 828 F.3d at 216. Spencer cannot supply any evidence of this.

Since the touchstone of discrimination is treating two groups differently based on

characteristics only one possesses, it is vital for Spencer to provide evidence that the

University has used the 9/12ths policy to pay men more than women. Instead, Spencer

merely argues that the University misapplied the 9/12ths policy to Shackleford and Dial.

But again, even if the University “erroneously or even purposely misapplied the . . .

policy, it is not proof of unlawful discrimination.” Dugan v. Albemarle Cty. Sch. Bd.,

293 F.3d 716, 722 (4th Cir. 2002).



                                            13
       As a final note, Spencer also alleges that the University, and its former provost,

engaged in unlawful retaliation because of her complaints about pay disparities. As the

district court noted, the facts supporting most of these allegations are exceedingly weak,

and the allegations themselves are mostly conclusory. See Spencer v. Virginia State

Univ., No. 3:16-cv-989, 2018 WL 627558, at *14–17 (E.D. Va. Jan. 30, 2018). Even if

Spencer’s characterization of the behavior is accurate, Spencer offers insufficient

evidence that each action was both material and undertaken because of her complaints

about salary equity. See Burlington N. & Santa Fe Ry. Co. v. White, 548 U.S. 53, 68

(2006) (holding that “a plaintiff must show that a reasonable employee would have found

the challenged action materially adverse . . . [meaning] it might have ‘dissuaded a

reasonable worker from making or supporting a charge of discrimination’”). That is not

to say no one harbored animus toward Spencer, but a personal conflict alone does not

constitute retaliation. Cf. Hawkins v. PepsiCo, Inc., 203 F.3d 274, 281 (4th Cir. 2000)

(“But Hawkins presents no facts that tend to show this allegedly disparate treatment was

due to race rather than Price’s admittedly low regard for Hawkins’ individual

performance.”). Because the district court correctly found that Spencer cannot establish a

prima facie case of retaliation, we do not address the merits of the University’s defenses.

       Accordingly, the judgment of the district court is

                                                                              AFFIRMED.
