Within-Grade Increases (Step Increases) for Federal Employees

Within-grade increases (WGIs), commonly called step increases, are automatic pay advancements within the General Schedule (GS) pay system that move an employee from one pay step to the next based on time in grade and acceptable performance. The GS system contains 15 grades, each with 10 steps, and WGIs represent the structured mechanism by which an employee progresses through those steps without a promotion. Understanding how step increases are earned, delayed, or denied is essential for any federal employee navigating federal pay scales and compensation.

Definition and scope

Under 5 U.S.C. § 5335, an employee under the General Schedule is entitled to a within-grade increase upon completion of a prescribed waiting period, provided performance has been at an acceptable level of competence. The Office of Personnel Management (OPM) implements this authority through 5 C.F.R. Part 531, Subpart D, which defines acceptable performance, waiting periods, and agency obligations when granting or withholding a WGI.

The scope of WGIs is limited to GS employees in the competitive and excepted service. Federal Wage System (FWS) employees and those under pay-banding systems — such as the Defense Civilian Intelligence Personnel System or the Department of Defense's National Security Personnel System — operate under separate step-progression rules that differ structurally from the GS model. Senior Executive Service members do not earn WGIs; SES pay is set within a range rather than structured around steps.

How it works

The waiting period for a WGI depends on which step range an employee currently occupies. OPM regulations establish three distinct waiting period tiers (5 C.F.R. § 531.405):

1. Steps 1–3: 52 calendar weeks of creditable service required to advance to the next step.
2. Steps 4–6: 104 calendar weeks (2 years) of creditable service required.
3. Steps 7–9: 156 calendar weeks (3 years) of creditable service required.

Creditable service includes time in a pay status or in a non-pay status not exceeding the limits specified in OPM guidance — typically no more than 52 weeks of non-pay status counts toward a WGI waiting period (5 C.F.R. § 531.406).

An acceptable level of competence determination is the performance threshold required for the WGI to proceed. Agencies assess this against the employee's most recent performance appraisal. A rating of "Minimally Satisfactory" or equivalent generally meets the threshold; a "Unacceptable" rating does not. The agency must notify the employee in writing at least 60 days before the end of the waiting period if it intends to withhold the increase, giving the employee an opportunity to improve performance.

The dollar value of each step increase varies by GS grade and locality pay area. At GS-7, Step 1, the base salary in the Washington-Baltimore-Arlington locality area for 2024 is set by OPM's annual pay tables, with each step representing approximately 3 percent of base pay — though the exact dollar increment differs across grades and steps.

Common scenarios

Standard progression: An employee hired at GS-9, Step 1 who maintains at least an acceptable performance rating advances to Step 2 after 52 weeks, Step 3 after another 52 weeks, and Step 4 after another 52 weeks. Advancement from Step 6 to Step 7 then requires 104 weeks. The full progression from Step 1 to Step 10 at the GS-9 level takes a minimum of 18 years of continuous creditable service under standard timing.

Quality step increases (QSIs): Agencies may grant a QSI — an additional step increase — to an employee whose performance is rated at the highest level under the agency's appraisal system (5 U.S.C. § 5336). A QSI resets the waiting period for the next regular WGI. This contrasts with a standard WGI: a regular WGI is entitlement-based once the waiting period and performance threshold are met, while a QSI is discretionary and competitive — agencies may limit QSIs based on available funds or performance distribution requirements.

Withheld WGI following unacceptable performance: If an employee's performance deteriorates to the unacceptable level, the agency withholds the WGI and must provide written notice. Once the employee returns to an acceptable performance level and demonstrates that level for 52 consecutive weeks, the WGI may be restored — but the waiting period for the next WGI begins from the date the restored increase takes effect, not from the original due date.

Break in service: A break in service of more than three calendar days generally interrupts the WGI waiting period. Credit for prior service may be restored under certain conditions, particularly when a former employee is rehired without a break exceeding one year, as addressed in 5 C.F.R. § 531.406.

Decision boundaries

The critical distinctions that determine WGI outcomes center on three axes:

Entitlement vs. discretion: A standard WGI is an entitlement when two conditions are satisfied — the waiting period is complete and performance is at least at the acceptable level. No supervisory discretion can withhold a WGI absent a documented, procedurally correct finding of unacceptable performance. A QSI, by contrast, is fully discretionary and subject to agency budget and policy constraints.

Withholding vs. denial: A withheld WGI is one delayed because performance fell below acceptable during the waiting period; it can be retroactively granted once performance recovers under certain conditions. A denied WGI, in contrast, is a final agency action taken after the required notice period when an employee fails to raise performance to an acceptable level. Employees who believe a WGI was improperly withheld or denied may pursue reconsideration through agency grievance procedures or, where applicable, through the federal employee appeals process.

GS step increases vs. FWS step increases: Federal Wage System employees advance through five steps (rather than ten) with waiting periods of 26 weeks (Steps 1–2), 78 weeks (Steps 2–3), 104 weeks (Steps 3–4), and 104 weeks (Steps 4–5), as established under 5 C.F.R. Part 532. The FWS progression is therefore faster in the early steps but governed by a structurally distinct set of regulations from the GS WGI framework.

Employees seeking a comprehensive orientation to the federal employment system, including how pay progression fits into broader employment conditions, can find foundational context on the Federal Employee Authority index.
