What the SLAS Grade III examination is
The Competitive Examination for Recruitment to Grade III of the Sri Lanka Administrative Service, generally known as the SLAS exam, is the gateway into the Sri Lanka Administrative Service, the premier general administrative cadre of the Sri Lankan public service. Officers who pass it go on to hold divisional and district level administrative posts and, over a career, rise into the senior administrative grades that run much of the day to day machinery of government. The exam is conducted by the Department of Examinations on behalf of the Ministry of Public Administration and the Public Service Commission, and its official gazette name is exactly that: “Competitive Examination for Recruitment to Grade III of the Sri Lanka Administrative Service.”
Two streams, two candidate pools
SLAS recruitment runs through two separate streams that should not be confused with each other. The Open stream is for general graduate applicants from outside government: any Sri Lankan citizen holding a Bachelor’s degree from a recognised university may apply, subject to the exact conditions stated in the notification current to that cycle. The Limited stream, by contrast, is restricted to serving government officers who already meet the service criteria set out in that cycle’s notification, effectively an internal promotion route into SLAS rather than an open graduate entry point. A candidate should check which stream a given notification covers before assuming the Open-stream qualification applies.
Worth noting for context: in at least one past cycle, the 2021 round, SLAS was not examined entirely on its own. The written papers were held as part of a common competitive examination shared with several other statutory Services, including Accountants, Planning, Education Administrative and Scientific, rather than as a fully separate SLAS-only paper. Whether a given future cycle repeats that arrangement or runs SLAS standalone is set out in that cycle’s own notification.
The stage-by-stage pattern
SLAS recruitment is a written examination followed by an interview. Candidates who clear the written papers proceed to interview, and the interview is the final stage before appointment. Beyond that two-stage structure, the detailed paper-by-paper breakdown (subjects, marks and duration) is set by the notification for each cycle rather than fixed once for good, so a candidate preparing should work from the current cycle’s own notification rather than an earlier one.
Scale: what the record shows
Vacancy numbers vary sharply between cycles and between streams. The 2021 Open stream carried 155 vacancies and the 2021 Limited stream carried 54. The 2026 Limited stream, by contrast, opened with 40 vacancies on a limited-competitive basis, plus a further 10 posts under a separate Merit Stream. These figures come from different cycles and different streams, so they should be read as points of reference for scale rather than as a trend line; a candidate should always confirm the vacancy count for the specific cycle and stream they are applying under from that cycle’s own gazette notification.
How to apply and the 2026 Limited cycle dates
For the 2026 Limited stream cycle, applications opened on 31 August 2026 and closed on 30 September 2026. Applications are submitted through the process the Department of Examinations sets out in the gazette notification for that cycle; the notification also carries the current fee, document requirements and the syllabus for the written papers. Because both the stream structure and the vacancy count change from one cycle to the next, this page’s schedule and vacancy figures each carry their own source and the date they were last checked, and figures that are not published in a source, including any total-applicant count, are left out rather than estimated.
