Justice Scalia
delivered the opinion of the Court.
Title VII of the Civil Rights Act of 1964 prohibits employers from using employment practices that cause a disparate impact on the basis of race (among other bases). 42 U. S. C. §2000e-2(k)(l)(A)(i). It also requires plaintiffs, before beginning a federal lawsuit, to file a timely charge of discrimination with the Equal Employment Opportunity Commission (EEOC). §2000e-5(e)(l). We consider whether a plaintiff who does not file a timely charge challenging the adoption of a practice — here, an employer's decision to exclude employment applicants who did not achieve a certain score on an examination — may assert a disparate-impact claim in a timely charge challenging the employer’s later application of that practice.
I
In July 1995, the city of Chicago (City) administered a written examination to over 26,000 applicants seeking to serve in the Chicago Fire Department. After scoring the examinations, the City reported the results. It announced in a January 26,1996, press release that it would begin drawing randomly from the top tier of scorers, i. e., those who scored 89 or above (out of 100), whom the City called “well qualified.” Those drawn from this group would proceed to the next phase — a physical-abilities test, background check, medical examination, and drug test — and if they cleared those hurdles would be hired as candidate firefighters. Those who scored below 65, on the other hand, learned by letters sent the same day that they had failed the test. Each was told he had not achieved a passing score, would no longer be considered for a firefighter position, and would not be contacted again about the examination.
The applicants in-between — those who scored between 65 and 88, whom the City called “qualified” — were notified that they had passed the examination but that, based on the City’s projected hiring needs and the number of “well-qualified” applicants, it was not likely they would be called for further processing. Tlie individual notices added, however, that because it was not possible to predict how many applicants would be hired in the next few years, each “qualified” applicant’s name would be kept on the eligibility list maintained by the department of personnel for as long as that list was used. Eleven days later, the City officially adopted an “Eligible List” reflecting the breakdown described above.
On May 16,1996, the City selected its first class of applicants to advance to the next stage. It selected a second on October 1, 1996, and repeated the process nine more times over the next six years. As it had announced, in each round the City drew randomly from among those who scored in the “well-qualified” range on the 1995 test. In the last round it exhausted that pool, so it filled the remaining slots with “qualified” candidates instead.
On March 31, 1997, Crawford M. Smith, an African-American applicant who scored in the “qualified” range and had not been hired as a candidate firefighter, filed a charge of discrimination with the EEOC. Five others followed suit, and on July 28,1998, the EEOC issued all six of them right-to-sue letters. Two months later, they filed this civil action against the City, alleging (as relevant here) that its practice of selecting for advancement only applicants who scored 89 or above caused a disparate impact on African-Americans in violation of Title VII. The District Court certified a class— petitioners here — consisting of the more than 6,000 African-Americans who scored in the “qualified” range on the 1995 examination but had not been hired.
The City sought summary judgment on the ground that petitioners had failed to file EEOC charges within 300 days after their claims accrued. See §2000e-5(e)(l). The District Court denied the motion, concluding that the City’s “ongoing reliance” on the 1995 test results constituted a “continuing violation” of Title VIL App. to Pet. for Cert. 45a. The City stipulated that the 89-point cutoff had a “severe disparate impact against African Americans,” Pinal Pretrial Order, Record, Doc. 223, Schedule A, p. 2, but argued that its cutoff score was justified by business necessity. After an 8-day bench trial, the District Court ruled for petitioners, rejecting the City’s business-necessity defense. It ordered the City to hire 132 randomly selected members of the class (reflecting the number of African-Americans the court found would have been hired but for the City’s practices) and awarded backpay to be divided among the remaining class members.
The Seventh Circuit reversed. 528 F. 3d 488 (2008). It held that petitioners’ suit was untimely because the earliest EEOC charge was filed more than 300 days after the only discriminatory act: sorting the scores into the “well-qualified,” “qualified,” and “not-qualified” categories. The hiring decisions down the line were immaterial, it reasoned, because “[t]he hiring only of applicants classified 'well qualified’ was the automatic consequence of the test scores rather than the product of a fresh act of discrimination.” Id., at 491. We granted certiorari. 557 U. S. 965 (2009).

A
Before beginning a Title VII suit, a plaintiff must first file a timely EEOC charge. In this case, petitioners’ charges were due within 300 days “after the alleged unlawful employment practice occurred.” § 2000e~5(e)(l). Determining whether a plaintiff’s charge is timely thus requires “identify[ing] precisely the ‘unlawful employment practice’ of which he complains.” Delaware State College v. Ricks, 449 U. S. 250, 257 (1980). Petitioners here challenge the City’s practice of picking only those who had scored 89 or above on the 1995 examination when it later chose applicants to advance. Setting aside the first round of selection in May 1996, which all agree is beyond the cutoff, no one disputes that the conduct petitioners challenge occurred within the charging period. The real question, then, is not whether a claim predicated on that conduct is timely, but whether the practice thus defined can be the basis for a disparate-impact claim at all.
We conclude that it can. As originally enacted, Title VII did not expressly prohibit employment practices that cause a disparate impact. That enactment made it an “unlawful employment practice” for an employer “to fail or refuse to hire or to discharge any individual, or otherwise to discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual’s race, color, religion, sex, or national origin,” §2000e-2(a)(l), or “to limit, segregate, or classify his employees or applicants for employment in any way which would deprive or tend to deprive any individual of employment opportunities or otherwise adversely affect his status as an employee, because of” any of the same reasons, § 2000e-2(a)(2). In Griggs v. Duke Power Co., 401 U. S. 424, 431 (1971), we interpreted the latter provision to “proscrib[e] not only overt discrimination but also practices that are fair in form, but discriminatory in operation.”
Two decades later, Congress codified the requirements of the “disparate impact” claims Griggs had recognized. Pub. L. 102-166, §105, 105 Stat. 1074, 42 U.S.C. §2000e-2(k). That provision states:
“(1)(A) An unlawful employment practice based on disparate impact is established under this subchapter only if—
“(i) a complaining party demonstrates that a respondent uses a particular employment practice that causes a disparate impact on the basis of race, color, religion, sex, or national origin and the respondent fails to demonstrate that the challenged practice is job related for the position in question and consistent with business necessity ... .”
Thus, a plaintiff establishes a prima facie disparate-impact claim by showing that the employer “uses a particular employment practice that causes a disparate impact” on one of the prohibited bases. Ibid, (emphasis added). See Ricci v. DeStefano, 557 U. S. 557, 578 (2009).
Petitioners’ claim satisfies that requirement. Title VII does not define “employment practice,” but we think it clear that the term encompasses the conduct of which petitioners complain: the exclusion of passing applicants who scored below 89 (until the supply of scores 89 or above was exhausted) when selecting those who would advance. The City “use[dj” that practice in each round of selection. Although the City had adopted the eligibility list (embodying the score cutoffs) earlier and announced its intention to draw from that list, it made use of the practice of excluding those who scored 88 or below each time it filled a new class of firefighters. Petitioners alleged that this exclusion caused a disparate impact. Whether they adequately proved that is not before us. What matters is that their allegations, based on the City’s actual implementation of its policy, stated a cognizable claim.
The City argues that subsection (k) is inapposite because it does not address “accrual” of disparate-impact claims. Section 2000e-5(e)(l), it says, specifies when the time to file a charge starts running. That is true but irrelevant. Aside from the first round of selection in May 1996 (which all agree is beyond the 300-day charging period), the acts petitioners challenge — the City’s use of its cutoff score in selecting candidates — occurred within the charging period. Accordingly, no one disputes that if petitioners could bring new claims based on those acts, their claims were timely. The issue, in other words, is not when petitioners’ claims accrued, but whether they could accrue at all.
The City responds that subsection (k) does not answer that question either; that it speaks, as its title indicates, only to the plaintiff’s “[b]urden of proof in disparate impact cases,” not to the elements of disparate-impact claims, which the City says are be found in § 2000e-2(a)(2). That is incorrect. Subsection (k) does indeed address the burden of proof — not just who bears it, however, but also what it consists of. It does set forth the essential ingredients of a disparate-impact claim: It says that a claim “is established” if an employer “uses” an “employment practice” that “causes a disparate impact” on one of the enumerated bases. § 2000e-2(k)(l)(A)(i). That it also sets forth a business-necessity defense employers may raise, ibid., and explains how plaintiffs may prevail despite that defense, § 2000e-2(k)(l)(A)(ii), is irrelevant. Unless and until the defendant pleads and proves a business-necessity defense, the plaintiff wins simply by showing the stated elements.
B
Notwithstanding the text of § 2000e-2(k)(l)(A)(i) and petitioners’ description of the practice they claim was unlawful, the City argues that the unlawful employment practice here was something else entirely. The only actionable discrimination, it argues, occurred in 1996 when it “used the examination results to create the hiring eligibility list, limited hiring to the ‘well qualified’ classification, and notified petitioners.” Brief for Respondent 23. That initial decision, it concedes, was unlawful. But because no timely charge challenged the decision, that cannot now be the basis for liability. And because, the City claims, the exclusion of petitioners when selecting classes of firefighters followed inevitably from the earlier decision to adopt the cutoff score, no new violations could have occurred. The Seventh Circuit adopted the same analysis. See 528 F. 3d, at 490-491.
The City’s premise is sound, but its conclusion does not follow. It may be true that the City’s January 1996 decision to adopt the cutoff score (and to create a list of the applicants above it) gave rise to a freestanding disparate-impact claim. Cf. Connecticut v. Teal, 457 U. S. 440, 445-451 (1982). If that is so, the City is correct that since no timely charge was filed attacking it, the City is now “entitled to treat that past act as lawful.” United Air Lines, Inc. v. Evans, 431 U. S. 553, 558 (1977). But it does not follow that no new violation occurred — and no new claims could arise — when the City implemented that decision down the road. If petitioners could prove that the City “use[dj” the “practice” that “causes a disparate impact,” they could prevail.
The City, like the Seventh Circuit, see 528 F. 3d, at 490-491, insists that Evans and a fine of cases following it require a different result. See also Ledbetter v. Goodyear Tire & Rubber Co., 550 U. S. 618 (2007); Lorance v. AT&T Technologies, Inc., 490 U. S. 900 (1989); Ricks, 449 U. S. 250. Those eases, we are told, stand for the proposition that present effects of prior actions cannot lead to Title VII liability.
We disagree. As relevant here, those cases establish only that a Title VII plaintiff must show a “present violation” within the limitations period. Evans, supra, at 558 (emphasis deleted). What that requires depends on the claim asserted. For disparate-treatment claims — and others for which discriminatory intent is required — that means the plaintiff must demonstrate deliberate discrimination within the limitations period. See Ledbetter, supra, at 624-629; Lorance, supra, at 904-905; Ricks, supra, at 256-258; Evans, supra, at 557-560; see also Chardon v. Fernandez, 454 U. S. 6, 8 (1981) (per curiam). But for claims that do not require discriminatory intent, no such demonstration is needed. Cf. Ledbetter, supra, at 640; Lorance, supra, at 904, 908-909. Our opinions, it is true, described the harms of which the unsuccessful plaintiffs in those cases complained as “present effect[s]” of past discrimination. Ledbetter, supra, at 628; see also Lorance, supra, at 907; Chardon, supra, at 8; Ricks, supra, at 258; Evans, supra, at 558. But the reason they could not be the present effects of present discrimination was that the charged discrimination required proof of discriminatory intent, which had not even been alleged. That reasoning has no application when, as here, the charge is disparate impact, which does not require discriminatory intent.
The Seventh Circuit resisted this conclusion, reasoning that the difference between disparate-treatment and disparate-impact claims is only superficial. Both take aim at the same evil — discrimination on a prohibited basis — but simply seek to establish it by different means. 528 F. 3d, at 491-492. Disparate-impact liability, the Court of Appeals explained, “‘is primarily intended to lighten the plaintiff’s heavy burden of proving intentional discrimination after employers learned to cover their tracks.’” Id., at 492 (quoting Finnegan v. Trans World Airlines, Inc., 967 F. 2d 1161, 1164 (CA7 1992)). But even if the two theories were directed at the same evil, it would not follow that their reach is therefore coextensive. If the effect of applying Title VII’s text is that some claims that would be doomed under one theory will survive under the other, that is the product of the law Congress has written. It is not for us to rewrite the statute so that it covers only what we think is necessary to achieve what we think Congress really intended. See Oncale v. Sundowner Offshore Services, Inc., 523 U. S. 75, 79-80 (1998).
The City also argues that, even if petitioners could have proved a present disparate-impact violation, they never did so under the proper test. The parties litigated the merits— and the City stipulated that the cutoff score caused disparate impact — after the District Court adopted petitioners’ “continuing violation” theory. App. to Pet. for Cert. 45a. That theory, which petitioners have since abandoned, treated the adoption and application of the cutoff score as a single, ongoing wrong. As a result, the City says, “petitioners never proved, or even attempted to prove, that use of the [eligibility] list had disparate impact,” Brief for Respondent 32 (emphasis added), since the theory they advanced did not require them to do so. If the Court of Appeals determines that the argument has been preserved it may be available on remand. But it has no bearing here. The only question presented to us is whether the claim petitioners brought is cognizable. Because we conclude that it is, our inquiry is at an end.
C
The City and its amici warn that our reading will result in a host of practical problems for employers and employees alike. Employers may face new disparate-impact suits for practices they have used regularly for years. Evidence essential to their business-necessity defenses might be unavailable (or in the case of witnesses’ memories, unreliable) by the time the later suits are brought. And affected employees and prospective employees may not even know they have claims if they are unaware the employer is still applying the disputed practice.
Truth to tell, however, both readings of the statute produce puzzling results. Under the City’s reading, if an employer adopts an unlawful practice and no timely charge is brought, it can continue using the practice indefinitely, with impunity, despite ongoing disparate impact. Equitable tolling or estoppel may allow some affected employees or applicants to sue, but many others will be left out in the cold. Moreover, the City’s reading may induce plaintiffs aware of the danger of delay to file charges upon the announcement of a hiring practice, before they have any basis for believing it will produce a disparate impact.
In all events, it is not our task to assess the consequences of each approach and adopt the one that produces the least mischief. Our charge is to give effect to the law Congress enacted. By enacting §2000e-2(k)(l)(A)(i), Congress allowed claims to be brought against an employer who uses a practice that causes disparate impact, whatever the employer’s motives and whether or not he has employed the same practice in the past. If that effect was unintended, it is a problem for Congress, not one that federal courts can fix.
Ill
The City asserts that one aspect of the District Court’s judgment still must be changed. The first round of hiring firefighters occurred outside the charging period even for the earliest EEOC charge. Yet the District Court, applying the continuing-violation theory, awarded relief based on those acts. Petitioners do not disagree, and they do not oppose the City’s request for a remand to resolve this issue. We therefore leave it to the Seventh Circuit to determine, to the extent that point was properly preserved, whether the judgment must be modified in light of our decision.
* * *
The judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Certain paramedics who scored between 65 and 88 were deemed “well qualified” pursuant to a collective-bargaming agreement, and certain veterans in the “qualified” range had five points added to their scores and therefore became “well qualified.”
In addition to the class members, the African American Fire Fighters League of Chicago, Inc., also joined the suit as a plaintiff.
All agree that a 300-day deadline applies to petitioners’ charges pursuant to 29 CFR §§ 1601.13(a)(4), (b)(1), 1601.80 (2009). Cf. EEOC v. Commercial Office Products Co., 486 U. S. 107, 112, 114-122 (1988).
Because the District Court certified petitioners as a class, and because a court may award classwide relief even to unnamed class members who have not filed EEOC charges, see Franks v. Bowman Transp. Co., 424 U. S. 747, 771 (1976), petitioners assert and the City does not dispute that the date of the earliest EEOC charge filed by a named plaintiff — that filed by Smith on March 31,1997 — controls the timeliness of the class’s claims. We assume without deciding that this is correct.
