delivered the opinion of the Court.
The Fair Labor Standards Act of 1938 (FLSA), 52 Stat. 1060, as amended, 29 U. S. C. §§201
et seq.,
exempts “bona fide executive, administrative, or professional” employees from overtime pay requirements. This case presents the question whether the Secretary of Labor’s “salary-basis” test for determining an employee’s exempt status reflects a permissible reading of the statute as it applies to public-sector employees. We also consider whether the Secretary has reasonably interpreted the salary-basis test to deny an
I
Petitioners are sergeants and a lieutenant employed by the St. Louis Police Department. They brought suit in 1988 against respondents, members of the St. Louis Board of Police Commissioners, seeking payment of overtime pay that they claimed was owed under § 7(a)(1) of the FLSA, 29 U. S. C. § 207(a)(1). Respondents argued that petitioners were not entitled to such pay because they came within the exemption provided by § 213(a)(1) for “bona fide executive, administrative, or professional” employees.
Under regulations promulgated by the Secretary, one requirement for exempt status under § 213(a)(1) is that the employee earn a specified minimum amount on a “salary basis.” 29 CFR §§ 541.1(f), 541.2(e), 541.3(e) (1996). According to the regulations, “[a]n employee will be considered to be paid 'on a salary basis’... if under his employment agreement he regularly receives each pay period on a weekly, or less frequent basis, a predetermined amount constituting all or part of his compensation, which amount is not subject to reduction because of variations in the quality or quantity of the work performed.” § 541.118(a). Petitioners contended that the salary-basis test was not met in their case because, under the terms of the St. Louis Metropolitan Police Department Manual, their compensation could be reduced for a variety of disciplinary infractions related to the “quality or quantity” of work performed. Petitioners also claimed that they did not meet the other requirement for exempt status under § 213(a)(1): that their duties be of an executive, administrative, or professional nature. See §§541.1(a)-(e), 541.2(a)-(d), 541.3(aMd).
The District Court found that petitioners were paid on a salary basis and that most, though not all, also satisfied the
II
The FLSA grants the Secretary broad authority to “de-fin[e] and delimi[t]” the scope of the exemption for executive, administrative, and professional employees. § 213(a)(1). Under the Secretary’s chosen approach, exempt status requires that the employee be paid on a salary basis, which in turn requires that his compensation not be subject to reduction because of variations in the “quality or quantity of the work performed,” 29 CFR § 541.118(a) (1996). Because the regulation goes on to carve out an exception from this rule for “[penalties imposed ... for infractions of safety rules of major significance,” § 541.118(a)(5), it is clear that the rule embraces reductions in pay for disciplinary violations. The Secretary is of the view that employees whose pay is adjusted for disciplinary reasons do not deserve exempt status because as a general matter true “executive, administrative, or professional” employees are not “disciplined” by piecemeal deductions from their pay, but are terminated, demoted, or given restricted assignments.
The FLSA did not apply to state and local employees when the salary-basis test was adopted in 1940. See 29 U. S. C. § 203(d) (1940 ed.); 5 Fed. Reg. 4077 (1940) (salary-basis test). In 1974 Congress extended FLSA coverage to virtually all public-sector employees, Pub. L. 93-259, § 6, 88 Stat. 58-62, and in 1985 we held that this exercise of power was consistent with the Tenth Amendment,
Garcia
v.
San Antonio Metropolitan Transit
Authority,
Respondents concede that the FLSA may validly be applied to the public sector, and they also do not raise any general challenge to the Secretary’s reliance on the salary-basis test. They contend, however, that the “no disciplinary deductions” element of the salary-basis test is invalid for public-sector employees because as applied to them it reflects an unreasonable interpretation of the statutory exemption. That is so, they say, because the ability to adjust public-sector employees’ pay — even executive, administrative or professional employees’ pay — as a means of enforcing compliance with work rules is a necessary component of effective government. In the public-sector context, they contend, fewer disciplinary alternatives to deductions in pay are available.
Because Congress has not “directly spoken to the precise question at issue,” we must sustain the Secretary’s approach so long as it is “based on a permissible construction of the statute.”
Chevron U. S. A. Inc.
v.
Natural Resources Defense Council, Inc.,
Respondents appeal to the “quasi military” nature of law enforcement agencies such as the St. Louis Police Department. The ability to use the full range of disciplinary tools against even relatively senior law enforcement personnel is essential, they say, to maintaining control and discipline in organizations in which human lives are on the line daily. It is far from clear, however, that only a pay deduction, and not some other form of discipline — for example, placing the offending officer on restricted duties — will have the necessary effect. Because the FLSA entrusts matters of judgment such as this to the Secretary, not the federal courts, we cannot say that the disciplinary-deduction rule is invalid as applied to law enforcement personnel.
B
The more fundamental objection respondents have to the disciplinary-deduction rule is a procedural one: The Secretary has failed to give adequate consideration to whether it really makes sense to apply the rule to the public sector. Respondents’ amici make the claim more specific: The Secretary’s failure to revisit the rule in the wake of our Garcia decision was “arbitrary” and “capricious” in violation of the Administrative Procedure Act (APA), 5 U. S. C. § 706(2)(A).
It is certainly true that application of the disciplinary-deduction rule to public-sector employees raises distinct is
III
A primary issue in the litigation unleashed by application of the salary-basis test to public-sector employees has been whether, under that test, an employee’s pay is “subject to” disciplinary or other deductions whenever there exists a theoretical possibility of such deductions, or rather only when there is something more to suggest that the employee is actually vulnerable to having his pay reduced. Petitioners in
The Court of Appeals rejected petitioners’ approach, saying that “[t]he mere possibility of an improper deduction in pay does not defeat an employee’s salaried status” if no practice of making deductions exists.
Because the salary-basis test is a creature of the Secretary’s own regulations, his interpretation of it is, under our jurisprudence, controlling unless “ ‘plainly erroneous or inconsistent with the regulation.’”

Bowen
v.
Georgetown Univ. Hospital,
h-H <
One small issue remains unresolved: the effect upon the exempt status of Sergeant Guzy, the officer who violated the residency requirement, of the one-time reduction in his pay. The Secretary’s regulations provide that if deductions which are inconsistent with the salary-basis test — such as the deduction from Guzy’s pay — are made in circumstances indicating that “there was no intention to pay the employee on a salary basis,” the exemption from the FLSA is “[not] applicable to him during the entire period when such deductions were being made.” 29 CFR § 541.118(a)(6) (1996). Conversely, “where a deduction not permitted by [the salary-basis test] is inadvertent, or is made for reasons other than lack of work, the exemption will not be considered to have been lost if the employer reimburses the employee for such deductions and promises to comply in the future.” Ibid.
Petitioners contend that the initial condition in the latter provision (which enables the employer to take corrective action) is not satisfied here because the deduction from Guzy’s pay was not inadvertent. That it was not inadvertent is true enough, but the plain language of the regulation sets out “inadvertence]” and “made for reasons other than lack of work” as
alternative
grounds permitting corrective action. Petitioners also contend that the corrective provision is unavailable to respondents because Guzy has yet to be reimbursed for the residency-based deduction; in petitioners’ view, reimbursement must be made immediately upon the discovery that an improper deduction was made. The language of the regulation, however, does not address the tim
* *■ *
Petitioners have argued, finally, that respondents failed to carry their affirmative burden of establishing petitioners’ exempt status even under the Secretary’s interpretation of the salary-basis test. Since, however, that argument was inadequately preserved in the prior proceedings, we will not consider it here. See

S. H. Kress & Co.,
It is so ordered.
Notes
Respondents contend that the District Court lacked jurisdiction over petitioners’ suit by virtue of the Eleventh Amendment. The Board of Police Commissioners, however, does not share the immunity of the State of Missouri. While the Governor appoints four of the board’s five members, Mo. Rev. Stat. § 84.030 (1994), the city of St. Louis is responsible for the board’s financial liabilities, §84.210, and the board is not subject to the State’s direction or control in any other respect. It is therefore not an “arm of the State” for Eleventh Amendment purposes.

v.
Port Authority Trans-Hudson Corporation,
Petitioners also contend that additional sergeants were actually subjected to disciplinary deductions, but that fact is not established by the portions of the record petitioners cite.
