ExploreAbout this exam
The Sri Lanka Administrative Service (SLAS) is the country's senior civil service cadre, and the SLAS competitive examination is the main open route into it for graduates who want a career in public administration rather than in a single technical department. Candidates are typically degree holders aiming at cadre positions that involve policy advice, district and divisional administration, and coordination across ministries. The selection process is deliberately broad: it tests general knowledge and current affairs, proficiency in Sinhala, Tamil and English, public administration and administrative law, the Constitution and public policy, economics and public finance, development planning and project management, and Sri Lankan history and culture, alongside quantitative and logical reasoning. Shortlisted candidates then face a structured interview or viva. Because the exam rewards wide reading rather than one textbook, preparation usually means building a current-affairs habit, working through past-style structured writing under time pressure, and practising essay answers with a clear argument.

What you'll study
About Sri Lanka Administrative Service Exam preparation
Who conducts the SLAS examination and where do I confirm the rules?
Recruitment to the Sri Lanka Administrative Service is handled through the Public Service Commission and the relevant ministry machinery. Rules on eligibility, medium, subjects and stages change between cycles, so treat any third-party summary as a guide only and confirm the current gazette notice and application instructions on the official commission website before you rely on them.
What is the exam format?
Expect a mix of objective papers testing general knowledge, language and reasoning, plus structured written papers and essay-style answers on administration, law, economics and development. Candidates who clear the written stages attend an interview or viva. The exact paper structure and medium options are set out in the official notice for each cycle, so check that notice rather than assuming last year's pattern.
How long is the exam and how many questions are there?
The official body publishes the current paper structure, time allocations and marking scheme with each recruitment notice. Those figures are not fixed across cycles, so this page does not quote them. Download the latest notice and syllabus from the commission's website and plan your practice sessions around the timings stated there.
How difficult is it, and what score do I need?
It is competitive because it draws strong graduates from many disciplines and rewards breadth over narrow specialisation. The passing or cut-off mark is determined per cycle and published by the official body, so no fixed figure should be assumed. Aim well above the minimum: in practice, selection depends on how you rank against other candidates, not on a single threshold.
Can I retake the exam if I am not selected?
Retake and eligibility rules, including age limits and the number of permitted attempts, are set by the official body for each cycle and can be revised. Check the current notice before planning a second attempt. If you are eligible again, treat the first attempt as diagnostic: identify which papers cost you marks and rebuild your schedule around those.
Which language should I write in?
The examination offers Sinhala, Tamil and English media, and language proficiency itself is assessed, so your choice affects both comprehension and scoring. Confirm the medium options and any compulsory language paper in the official notice. If you write in a second language, practise timed answers in it early, because vocabulary under pressure is usually the limiting factor, not subject knowledge.
In what order should I study the subjects?
Start with the Constitution, public administration and administrative law, since these supply the vocabulary and institutional map that economics, policy and development answers all rely on. Layer in economics and public finance next. Keep current affairs and languages running continuously in short daily blocks, and leave history and culture for spaced revision rather than a single block.
What are the most common failure modes?
Three recur. First, reading widely but never writing timed answers, so structured papers expose weak argument and poor time allocation. Second, treating current affairs as a last-minute cram instead of a daily habit. Third, ignoring the language paper on the assumption that subject knowledge carries it. A fourth is neglecting the interview: prepare to defend your own written positions and to discuss district-level realities.
How should I prepare for the interview or viva?
Treat it as an extension of the written exam. Be ready to explain why you chose particular answers, discuss current administrative issues with concrete examples, and show familiarity with how divisional and district administration actually works. Read the commission's own guidance on the interview stage, practise aloud with a partner, and prepare specific, honest reasons for wanting a public-service career.

No. This is independent study material written for candidates preparing on their own. It is not produced, endorsed or reviewed by the Public Service Commission, the Ministry of Public Administration or any government body. Verify every procedural fact - eligibility, dates, fees, medium, syllabus - against the official commission website before you act on it.
