There are two principal pay systems for federal employees: (1) The General Schedule (GS), which applies to "white-collar" employees and which is divided into numbered pay grades and subdivided into rates of pay or "steps" within each grade, with the salary for each "step" uniform nationwide; and (2) the prevailing wage system (WS), which primarily applies to "blue-collar" employees specifically excluded from GS, and which is also divided into grades and subdivided into "steps," with the rates of pay for each "step" based upon prevailing wage rates for comparable work in local areas. Salary treatment for employees shifted or hired into the GS system is governed by 5 U.S.C. 5334 and implementing regulations. An employee's salary after promotion is determined by reference either to the "highest previous rate" rule under 5334(a) and the governing regulation or to the "two-step increase" rule under 5334(b), which provides for such an increase when an employee is promoted to a position in a higher "grade." Title 5 U.S.C. 5331 assigns the word "grade" the meaning given by 5102(a)(5), which in turn defines the word as those positions sufficiently similar to warrant their inclusion within one range of rates of basic pay "in the General Schedule." Respondents, after being promoted from WS to GS positions, were administratively held to be entitled to a salary increase determined by the "highest previous rate" rule, which gave them a smaller increase than they would have received under the "two-step increase" rule. They then filed an action in the Court of Claims, contending that they were entitled to a two-step increase in pay pursuant to 5334(b). The Court of Claims upheld their claim and accordingly invalidated a regulation which construed 5334(b) as limited to transfers or promotions within the GS.
Section 5334(b) does not apply to WS employees promoted to GS positions. Pp. 560-567.

JUSTICE O'CONNOR delivered the opinion of the Court.
The issue in this case is whether 5 U.S.C. 5334(b), which requires a two-step pay increase for federal employees "promoted . . . to a position in a higher grade," applies to prevailing wage rate employees promoted to General Schedule positions. We hold that it does not apply, and reverse the judgment of the Court of Claims.
This case involves the relationship between the two principal pay systems for federal employees and the pay treatment to which an employee moving from one system to another is entitled. Both systems are governed by Title 5, United States Code.
One of the pay systems, the General Schedule (GS), 5 U.S.C. 5331 et seq. (1976 ed. and Supp. V), applies to federal "white-collar" employees. See R. Vaughn, Principles [454 U.S. 555, 557] of Civil Service Law 6.2(a), p. 6-4 (1976) (hereinafter Vaughn). The GS is divided into 18 numbered grades; as the number of the grade increases, so do pay and responsibilities. 5104 and 5332 (1976 ed. and Supp. V). The grades are subdivided into rates of pay or "steps." 5332. The salary for each step of each grade in the GS is uniform nationwide. 1
The second principal pay system is the prevailing rate wage system (WS), 5 U.S.C. 5341 et seq. (1976 ed. and Supp. V), which primarily applies to those federal "blue-collar" employees specifically excluded from the GS. See 5102(b), (c)(7), 5331, and 5342(a)(2)(A); Vaughn 6.2(b), p. 6-17. The WS also is divided into grades and subdivided into "steps." The rate of pay for each step within each grade is based upon wage surveys of prevailing rates for comparable work in local wage areas. 5343 (1976 ed. and Supp. V); Office of Personnel Management, Federal Personnel Manual, Supp. 532-1, 56 (Apr. 14, 1980) (hereinafter FPM). Pay rates for positions within the WS thus vary from one locale to another.
Salary treatment for GS employees who change their employment status and employees shifted or hired into the GS system is governed by 5 U.S.C. 5334 (1976 ed. and Supp. V) and regulations promulgated pursuant thereto. Under the statute, an employee's salary after promotion is determined by reference either to the "highest previous rate" rule 2 or to the "two-step increase" rule. 3 [454 U.S. 555, 558]
Prior to July 1973, all six respondents worked as federal civilian employees for the Supervisor of Shipbuilding, Department of the Navy. In those positions, they were paid pursuant to the WS. Between July 1973 and October 1974, all were promoted to positions covered by the GS. 4 After his promotion, Libretto learned that the other respondents received a salary increase equivalent to a two-step pay increase on their appointment to the GS positions. 5 Since Libretto's [454 U.S. 555, 559] increase was based upon the "highest previous rate" rule and was much smaller, he filed a claim with the Department of the Navy. As a result, the Navy reexamined the salary treatment afforded respondents. Concluding the salaries of all should have been determined by applying the "highest previous rate" rule, the Navy denied Libretto's claim and notified the other respondents their salaries would be reduced accordingly.
Respondents unsuccessfully pursued their administrative remedies and then filed this action in the Court of Claims under the Tucker Act, 28 U.S.C. 1491, and the Back Pay Act of 1966, 5 U.S.C. 5596. Respondents contended they were entitled to a two-step increase in pay pursuant to 5 U.S.C. 5334(b) (1976 ed., Supp. V) The Government opposed the claims on the ground that 5334(b) applies only to promotions within the GS and not to shifts or promotions between the WS and the GS, which are governed by 5334(a).
The Court of Claims, reasoning that respondents had been "promoted" within the meaning of 5 CFR 531.202(h)(2) [454 U.S. 555, 560] (1969), 6 determined they were entitled to a two-step increase under 5334(b). Accordingly, the court invalidated, as inconsistent with the statute, 5 CFR 531.204(a) (1969), which construed 5334(b) as limited to transfers or promotions within the GS. 220 Ct. Cl. 278, 599 F.2d 411 (1979).
After remand, the parties stipulated to the amount of respondent's recovery, and the court entered final judgment on August 8, 1980. We granted the Government's petition for writ of certiorari to the United States Court of Claims. 450 U.S. 993 (1981). We have jurisdiction based upon 28 U.S.C. 1255.
We look first to the language and organization of the statutes governing General Schedule pay rates and the prevailing rate wage system. If the statutory language is clear, it is ordinarily conclusive. See Consumer Product Safety Comm'n v. GTE Sylvania, Inc., 447 U.S., 102 (1980).
Section 5334 is part of subchapter III, chapter 53 of Title 5, entitled "General Schedule Pay Rates." Subsection 5334(a) describes the general conditions, including promotions, under which a GS employee is entitled to a change in basic pay. It directs simply that the rate is "governed by regulations prescribed by the [Civil Service Commission]. . ." Following that direction, the Civil Service Commission promulgated the "highest previous rate" rule. 7 [454 U.S. 555, 561]
In subsection 5334(b), on the other hand, Congress restricted the Commission's discretion in one limited situation:
The Wage System, on the other hand, is governed by subchapter IV of chapter 53, Title 5. No express statutory provision in subchapter IV defines how an employee's salary should be set when a WS employee is promoted to a GS position. Thus, the only applicable statutory provisions are those found in subchapter III and its accompanying regulations, which specifically limit the two-step increase to promotions within the GS. Nothing in the statutory language indicates Congress intended to include employees promoted from WS to GS within the two-step requirement of 5334(b). Absent such language, the statute and the accompanying regulations reveal a congressional intend to apply the two-step increase provision of 5334(b) only to promotions or transfers of employees already within the GS system.
Although the language of the statute is clear, any lingering doubt as to its proper construction may be resolved by examining the legislative history of the statute and by according [454 U.S. 555, 562] due deference to the longstanding interpretation given the statute by the agencies charged with its interpretation. See NLRB v. Bell Aerospace Co,. 416 U.S. 267 (1974). The legislative history of 5334(b) reinforces the apparent intent of the statutory language. The predecessor to 5334(b) was 802(b) of the Classification Act of 1949, 63 Stat. 954, 5 U.S.C. 1071 et seq. (1946 ed. and Supp. IV) (1949 Act). 8 Through the 1949 Act, Congress completely revised the Classification Act of 1923, Pub. L. 516, 42 Stat. 1488, 5 U.S.C. 661 et seq. (1925-1926 ed). Under the latter statute, an employee who was at the top step of the his grade could receive little or no salary increase upon promotion to a higher grade. That inequity resulted because the salary for the higher steps in one grade could equal or exceed the salary for the lower steps in the next higher grade. Congress' 1949 revision plainly undertook to correct this problem: the 1949 Act numbered among its stated purposes the need "to permit the solution of certain troublesome problems or to avoid unintentional pay inequities in the conduct of various personnel transactions." S. Rep. No. 847, 81st Cong. 1st, Sess., 4 (1949). Congress, moreover, understood the precise nature of the salary overlap problem. The Committee Reports which accompanied the proposed revisions explained:
Moreover, in 1972, approximately one year before respondents' promotions, Congress undertook a comprehensive examination of the prevailing wage statutes and amended existing laws to declare congressional policy for the payment of prevailing wage employees. See S. Rep. No. 92-791, p. 1 (1972). Congress' stated purpose was to codify existing law. Ibid. As part of the 1972 amendments, Congress for the first time directed that a grading system be established and maintained for prevailing wage employees. 10 5 U.S.C. 5346 [454 U.S. 555, 564] (1976 ed. and Supp. V). Even then, Congress made no effect to correlate the WS grades with those used in the GS. By that time, the agency practice of specifically limiting 5334(b) and its predecessor to transfers between Classification Act, or GS, positions had been followed for nearly 25 years. 11 Congress' failure to correct that practice, if it did not correspond with congressional intend, at the very time Congress was revamping the laws applicable to pay for prevailing wage positions provides further evidence of its intent that 802(b) and, later, 5334(b) apply only to GS employees. See United States v. Bergh, 532 U.S. 40 (1956).
The absence of any indication that Congress intended 5334(b) to apply to promotions into the GS from the WS is hardly surprising, since the two systems have no necessary or obvious relationship. First, because the WS involves an entirely separate pay structure based on prevailing rates in local wage areas, no necessary overlap occurs between WS and GS salaries. In fact, since WS rates vary by locale, an employee changing from a WS position to a GS position could receive a greater salary, a lesser salary, or the same salary as another employee making the identical change in another part of the country. Moreover, although by definition a change to a higher grade within the GS system involves a change to a position with greater responsibility (see 5 U.S.C. 5102(a)(5) (1076 ed. Supp. V)), no similar relationship necessarily exists between a WS grade and a GS Grade. 12 [454 U.S. 555, 565]
Although the legislative history does not expressly indicate that Congress intended to limit 5334(b) and its predecessor to GS employees, the history provides ample indication that such was Congress' intent. Moreover, the reasons for enactment of the provision are consistent with such a limitation.
Although not determinative, the construction of a statute by those charged with its administration is entitled to great deference, particularly when that interpretation has been followed consistently over a long period of time. See Piper v. Chris-Craft Industries, Inc., 430 U.S. 1 (1977). In this instance, the agency responsible for proposing and administering 5334(b) has consistently construed it to apply only to promotions within the GS.
Section 802(b) of the 1949 Act was drafted and submitted to the Congress by the Civil Service Commission. 13 Soon after its enactment, the Civil Service Commission promulgated regulations interpreting the section. The first regulations guaranteed a pay increase to one promoted "to a higher grade between Classification Act [GS] positions . . . ." 15 Feb. Reg. 7868 (1950), 5 CFR 25.104(a) (Supp. 1951). 14 In contrast, an employee promoted or transferred from another [454 U.S. 555, 566] pay system into the Classification Act system was subject to the "higher previous rate" rule. 15 Feb. Reg. 1235 (1950), 5 CFR 25.103(b) (Supp. 1951). Subsequent versions of the regulations continued to apply the automatic salary increase of 802(b) and, later, of 5334(b), only to promotions or transfers within the Classification Act, or GS, System. 15 In fact, the regulation in effect when respondents were promoted expressly provided that the two-step pay increase provision of 5334(b) applied "only (i) to a transfer from one General Schedule position to a higher General Schedule position, and (ii) to a promotion from one General Schedule grade to a higher General Schedule grade." 33 Feb. Reg. 12450 (1968), 5 CFR 531.204(a)(1) (1969). 16
The language of the statute, the entire statutory scheme, the legislative history, and consistent administrative interpretation [454 U.S. 555, 567] all demonstrate the soundness of the Government's position that 5334(b) is inapplicable to promotions from the Wage System to the General Schedule.
The judgment of the Court of Claims is reversed.
[ Footnote 2 ] The "highest previous rate" rule derives from 5. U.S.C. 5334(a) (1976 ed., Supp. V), which provides in part:
(7) his position is changed from one grade to another grade."
At the time of respondents' promotions, 33 Feb. Reg. 12450 (1968), 5 CFR 531.203(c) (1969), one of the regulations prescribed by authority of 5334(a), provided in part:
[ Footnote 3 ] The "two-step increase" rule is codified in 5 U.S.C. 5334(b) (1976 ed., Supp. V), which provides in pertinent part:
[ Footnote 4 ] Respondents' changes of position were as follows: Clark, from WS ship surveyor (shipfitter) to GS quality assurance specialist; D'Aversa, from WS ship surveyor (pipefitter) to GS production controller; Libretto, from WS ship surveyor (machinist) to GS engineering technician; Proto, from WS ship surveyor (electrician) to GS production controller, and later to GS contract negotiator; Scialpi, from WS ship surveyor (shipfitter) to GS contract negotiator; and Wolfus, from WS ship surveyor (machinist) to GS contract negotiator.
[ Footnote 5 ] The parties agree that Libretto's salary after promotion was determined by reference to the "highest previous rate: rule. Because his WS salary fell between two steps of his new GS grade, he was given the higher [454 U.S. 555, 559] salary level of the new GS grade. The parties disagree as to the method used to determine the postpromotion salaries of the remaining respondents. Respondents allege they were simply given a two-step increase, pursuant to 5334(b). The Government explains their GS salaries were originally determined by first applying the provision of subchapter S8-3d of the FPM, Supp. 532-1, Inst. 8 (Jan. 16, 1973), which stated that an employee promoted to a WS position is entitled to be paid at the lowest scheduled rate that exceeds his existing rate of pay by no less than a one-step increment of the category from which he was promoted. Once this adjustment had been made, the new GS salaries of these respondents were computed by applying the "highest previous rate" rule of 5 CFR 531.203(c) (1969) to the adjusted rates of pay. Thus, each of these respondents was awarded two salary increases for a single change of position. If this method was utilized, the salary determinations were obviously erroneous because subchapter S8-3d and the "highest previous rate" rule of 5 CFR 531.203(c) (1969) are not applicable to the same personnel action. Regardless of the method used, the effect was to give all respondents except Libretto the equivalent of a two-step increase.
[ Footnote 6 ] At the time of respondents' promotions, 33 Feb. Reg. 12449 (1968), 5 CFR 531.202(h) (1969), provided:
(2) A lower rate paid under authority other than subchapter III of chapter 53 of title 5, United States Code, to a higher rate within a General Schedule grade."
[ Footnote 7 ] See 5 CFR 531.203(c) (1969). The Civil Service Commission promulgated the initial regulation. In 1978, Congress substituted the Office of Personnel Management for the Civil Service Commission. 5 U.S.C. 1101 et seq. (1976 ed. Supp. V). The terms of the regulation have remained consistent since 1950. See n. 15, infra.
[ Footnote 8 ] In 1962, the Act was amended to provide a two-step rather than a one-step salary increase. 5 U.S.C. 1132(b) (1958 ed., Supp. V).
[ Footnote 9 ] See Staff Report, President's Panel of Federal Compensation 107 (Jan. 1976).
[ Footnote 10 ] In 1965, President Johnson directed all executive agencies to coordinate their wage policies and practices under the leadership of the Chairman of the Civil Service Commission. See FPM, Supp. 532-1, App. A-1, B-B-1 (Nov. 16, 1965). As a result, the Coordinated Federal Wage System was developed. In 1972, Congress amended the prevailing wage [454 U.S. 555, 564] statutes. The purpose of the 1972 amendments was to codify existing law and enact a system for all agencies to use for determining the prevailing wage rates. S. Rep. No. 92-791, p. 1 (1972). As part of the 1972 amendments, Congress added 5 U.S.C. 5346, which directed the Civil Service Commission to establish and maintain a job grading system for positions covered by subchapter IV. That was the first time Congress directed the maintenance of a uniform system for WS employees.
[ Footnote 11 ] See Part IV, infra.
[ Footnote 12 ] The two systems are simply independent. Unlike the 10 steps or rates of pay in most GS grades (see 5 U.S.C. 5332 (1976 ed. and Supp. V)), the WS currently uses only 5 rates for each position (see 5 U.S.C. 5343 [454 U.S. 555, 565] (c)(2) (1976 ed. and Supp. V)) and before 1972 used only 3 rates. See H. R. Rep. No. 92-339, p. 6 (1971); S. Rep. No. 92-791, p. 2 (1972). In addition, the range of pay in a GS grade is approximately 30 percent of the base rate, but the range in the WS is only approximately 16 percent. See 5 U.S.C. 5332 (chart), 5343(e)(A)-(E) (1976 ed. and Supp. V). Moreover, the periodic step increase in the WS occur considerably more quickly than in the GS. Compare 5 U.S.C. 5335(a)(1)-(3) with 5 U.S.C. 5343(e)(A)-(C) (1976 ed. and Supp. V). As a result, the maximum rate of pay for a position is more often reached, and in a far shorter time, by a WS employee than by a GS employee.
[ Footnote 13 ] See S. Rep. No. 847, 81st Cong., 1st Sess. 1 (1949).
[ Footnote 14 ] Congress specifically excluded prevailing rate position from the Classification Act of 1949. 5 U.S.C. 1082(7) (1946 ed., Supp. IV). Those positions remain specifically excluded from the General Schedule. 5 U.S.C. 5102(c)(7), 5331 (1976 ed. and Supp. V).
[ Footnote 15 ] See, e. g., 15 Feb. Reg. 7868 (1950), 5 CFR 25.104(a) (Supp. 1951) (refers to "[a]n employee promoted, repromoted or transferred to a higher grade between Classification Act positions or grades"); 25 Feb. Reg. 7147 (1960), 5 CFR 25.104(a) (1961) ("[t]he requirements of section 802(b) of the [Classification] Act apply in repromotion actions and in transfers involving promotions between Classification Act grades"); 28 Fed. Reg. 10948 (1963), 5 CFR 531.204(a)(1) (1964) ("[t]he requirements of section 802(b) of the [A]ct, apply in a transfer involving a promotion between Classification Act grades"); 33 Feb. Reg. 12450 (1968), 5 CFR 531.204(a) (1969) ("[t]he requirements of section 5334(b) of title 5, United States Code, apply only (i) to a transfer from one General Schedule position to a higher General Schedule position, and (ii) to a promotion from one General Schedule grade to a higher General Schedule grade").
[ Footnote 16 ] The General Accounting Office, authorized to settle and adjust "[a]ll claims and demands whatever . . . against [the Government]," 31 U.S.C. 71, 72, has consistently determined that the "highest previous rate" rule, rather than the automatic step-increase provision, governs transfers or promotions from a WS position to a GS position. See, e. g., In re Nail, 59 Comp. Gen. 209 (1980); Letter Decision, 52 Comp. Gen. 695 (1973); Letter Decision, 52 Comp. Gen. 671 (1973); Letter Decision, 44 Comp. Gen. 518 (1965).
