The federal government's top non-executive experts can no longer expect near-universal high marks. A final rule from the Office of Personnel Management and the Office of Management and Budget lets OPM cap how many senior-level (SL) and scientific or professional (ST) employees receive top performance ratings, ending a prohibition on forced rating distributions for that group. The rule, titled "Managing Senior Professional Performance," appeared in the Federal Register on Oct. 19, 2026, and takes effect Nov. 18, 2026.
SL and ST positions are established under 5 U.S.C. 5376 and are classified above GS-15. The rule amends 5 CFR Parts 351, 430, 451, 534, 537, 630 and 894, with parallel changes from OMB to 5 CFR Part 1330 (Docket OPM-2025-0011).
In the rule's own words, OPM and OMB "are issuing a final rule to strengthen the performance appraisal of senior-level (SL) and scientific or professional (ST) employees."
Why OPM Says 90 Percent High Ratings Is a Problem
OPM built its case on rating data. According to the rule, governmentwide figures showed that in fiscal years 2023 and 2024, approximately 90 percent of senior professionals received ratings at Levels 4 and 5, while less than half of one percent received ratings below Level 3, "Fully Successful."
The agency also cited the 2024 Federal Employee Viewpoint Survey, in which only 47% of federal employees agreed with the statement, "In my work unit, differences in performance are recognized in a meaningful way." The rule notes this was the lowest positive response rate for any question and has consistently been the lowest over the past three years. OPM noted that the data "raise concerns regarding rating inflation and the effectiveness of existing appraisal systems in holding senior professionals accountable for performance."
OPM first laid out the changes in a proposed rule published Feb. 24, 2026 (91 FR 8763). The agency received 12 comments during the 30-day comment period, nine of which were posted to Regulations.gov. One commenter challenged OPM's authority to change the senior professional evaluation system under the Senior Professional Performance Act of 2008; OPM finalized the rule anyway.
How the Standardized Distribution for SL and ST Employees Works
The rule makes four structural changes. It creates a new subpart of Part 430 devoted only to senior professional appraisal and aligned more closely with SES appraisal regulations. It eliminates senior professional appraisal programs, the separate programs agencies previously had to maintain. It removes the ban on a standardized distribution of rating levels. And it enhances OPM oversight of the appraisal process.
The central provision is the distribution authority. The rule states that "OPM eliminates the prior prohibition on forced, or standardized, distribution for senior professionals and provides that OPM may establish a standardized distribution of some or all rating levels for agencies to apply with respect to their senior professional cohorts." Senior professionals appointed under Schedules C and G may be excluded from those requirements.
OPM explained the exclusion as a safeguard, mirroring the approach it took for the SES, where noncareer appointees were also carved out. The exclusion of Schedule C and Schedule G appointees, the rule says, "eliminates even the perception that rating distributions could be used in a manner that favors issuing high ratings to political appointees over career employees."
The rule also describes a release valve. Where an agency believes a distribution limit does not fit because its senior professionals performed exceptionally, OPM's new senior professional appraisal system provides that the President may waive the requirement by certifying that the agency's senior professionals' performance was outstanding during the relevant period.
Dropping separate appraisal programs, OPM argued, relieves agencies of requirements in subpart B of Part 430 "that are not well-suited to managing senior professional performance." The director of OPM certified that the rule will not have a significant economic impact on a substantial number of small entities "because it will apply only to Federal agencies and employees."
A 40% Cap on Top General Schedule Ratings Is Already in Motion
The senior professional rule runs alongside a broader push across the workforce. Government Executive reported Oct. 20 that OPM in September directed agencies to limit top scores, Level 5 "outstanding" and Level 4 "exceeds fully successful," to no more than 40% of their General Schedule employees in this year's review cycle. According to the outlet, OPM finalized regulations in July that removed a longstanding ban on a forced distribution system.
Agencies have also stood up calibration panels staffed with senior executives at OPM's direction. OPM guidance quoted by Government Executive spells out their limits: "A calibration panel is not a rating board that re-rates employees independently." Instead, the guidance says, the panel evaluates whether proposed ratings are supported by evidence, applied consistently across organizations and aligned with agency performance standards.
Employees and managers told the outlet they have been left in the dark about how the changes are being carried out. A Veterans Affairs manager said four of his five direct reports had "quantifiably achieved at least a 4, but I'm not allowed to give them all a final rating that high." OPM spokesperson Kiki Nyoh said in a statement that the 40% cap "best balances meaningful, standards-based ratings with recognizing outstanding performance," adding, "We will closely monitor FY 2026 results and use that data to guide future appraisal cycles."
The ratings carry real weight. Government Executive noted that top scores make some employees eligible for financial and time-off awards, and that OPM in July finalized a rule emphasizing recent performance reviews over tenure in reductions in force. The senior professional rule itself amends Part 351, the reduction-in-force regulations.
What It Means for Contractors
The rule does not apply to contractor personnel, and OPM's small-entity certification confirms it reaches only federal agencies and employees. Its effects on industry are indirect, and any such effects are inference rather than something the rule states.
SL and ST positions are senior technical and professional posts, and some of those officials may have a hand in shaping requirements and overseeing programs that contractors support. A ratings regime in which only a fixed share can earn top marks could change how those officials weigh risk, collaboration and visible results. Government Executive reported that in internal comments, many agencies warned that forced distribution reduces collaboration and cohesion among employees, a dynamic that could surface in integrated program offices where government and contractor staff work side by side.
Retention is a second item to watch. If senior technical staff see fewer paths to top ratings and the awards attached to them, some could weigh leaving government service, which would affect both the contractor hiring pool and the continuity of government technical counterparts. Neither source predicts this outcome. Firms supporting acquisition programs may want to track staffing changes among their government counterparts as the first rating cycle under the new rules plays out after Nov. 18.
