CSS Exam in Pakistan: The Complete FPSC Guide

The Central Superior Services examination is the entry route into Pakistan's federal civil service — the competitive examination through which the country recruits its Assistant Commissioners, Assistant Superintendents of Police, diplomats, tax officers and audit officers. It is conducted annually by the Federal Public Service Commission (FPSC), and it is one of the most selective examinations in the country.

How selective? In the CSS 2025 cycle, 12,792 candidates appeared for the written examination and 354 passed — a pass rate of 2.77 per cent. The previous year's figure was 2.53 per cent.

This guide walks through the entire process, stage by stage, with the numbers and rules that actually govern it.

The examination at a glance

The six stages, in order

Candidates frequently underestimate how long the full cycle takes. From the screening test to final group allocation, a single CSS cycle commonly runs well beyond a year.

1. MPT — MCQ-Based Preliminary Test (screening)
2. Written examination — twelve papers over roughly two weeks
3. Written result — historically several months to over a year later
4. Psychological assessment — tests, group discussion and interview
5. Viva voce — 300 marks before a panel
6. Medical examination, final merit list and group allocation

Stage 1: The MPT screening test

Introduced from the CSS 2022 cycle, the MCQ-Based Preliminary Test filters the applicant pool before the written examination. Its specifications:

Section breakdown

• English — 50 marks
• Islamic Studies (or Civics & Ethics for non-Muslim candidates) — 20 marks
• Urdu — grammar, usage and translation — 20 marks
• Remaining marks — quantitative, analytical and mental reasoning, together with Everyday Science, Current Affairs and Pakistan Affairs

How difficult is the MPT, really?

This is where a great deal of misplaced anxiety accumulates. The evidence suggests the MPT is a modest filter rather than the main obstacle.

In the CSS 2022 MPT, FPSC's result notification recorded that of 49,038 candidates who appeared, 48,787 qualified — a pass rate of 99.50 per cent, with only 247 candidates failing to clear it. With no negative marking and a 33 per cent threshold, a prepared candidate should treat the MPT as a formality to be cleared efficiently, not as the focus of a year's preparation.

The MPT for the CSS 2026 cycle was held on 9 November 2025; the CSS 2027 MPT was scheduled for 8 November 2026.

Stage 2: The written examination

This is the real examination. Twelve papers, 1,200 marks, each paper three hours long. Most papers carry a Part-I objective section — collected after approximately thirty minutes — followed by a Part-II subjective section. Optional papers generally carry 20 MCQs, with Applied Mathematics and Pure Mathematics as exceptions.

The six compulsory papers (600 marks)

Passing criteria

• 40 per cent in each compulsory paper
• 33 per cent in each optional paper
• 50 per cent aggregate — 600 out of 1,200 — to qualify for the viva voce

The aggregate requirement is where most candidates' campaigns end, and the reason is well documented. FPSC has publicly acknowledged that the largest concentration of failure occurs in the two English papers — a subject covered in depth in our essay guide.

Stage 2b: Choosing your optional subjects (600 marks)

Optional papers account for half the written marks, which makes subject selection one of the highest-leverage decisions in the entire preparation.

Selection rules

• Your chosen subjects must total exactly 600 marks
• You may not take more than 200 marks from any single group
• A 200-mark subject consists of two papers; a 100-mark subject is one paper

The seven groups

A word of caution on the popular search for "high-scoring subjects": year-to-year variation in paper difficulty and examiner marking means apparent scoring trends are unstable. Subject overlap — the extent to which an optional reinforces your compulsory papers — is a more reliable basis for selection than any published scoring league table.

Stage 3: Psychological assessment

Candidates who clear the written examination proceed to a psychological assessment comprising written tests, a group discussion and an interview with a psychologist.

An important structural point that is often misunderstood: the psychological assessment carries no separate marks. Its findings are provided to the viva voce panel and inform the 300 marks awarded there. It is not a stage you can pass or fail in isolation, and it is not something to be gamed — assessors are looking at consistency of personality and reasoning under observation.

Stage 4: The viva voce (300 marks)

The interview carries 300 marks, and a candidate must secure at least 100 marks to pass.

This stage is decisive in a way the arithmetic makes plain. With 1,200 written marks and 300 viva marks feeding a 1,500-mark merit total, the viva represents a fifth of your final standing — and because written scores among qualifiers cluster relatively tightly, viva performance frequently determines both selection and which occupational group a candidate receives.

Stage 5: Medical examination

Successful candidates undergo a medical fitness examination covering vision, hearing, height and weight, and laboratory tests. Meeting the prescribed standards is a mandatory condition of appointment.

Stage 6: Final merit and group allocation

Final merit is computed on 1,500 marks — the 1,200-mark written examination plus the 300-mark viva voce. The MPT, the medical examination and the psychological assessment are qualifying stages and do not contribute marks to the merit total.

Occupational groups

CSS recruits BPS-17 officers into twelve occupational groups and services, including:

• Pakistan Administrative Service (PAS) — formerly the District Management Group
• Police Service of Pakistan (PSP)
• Foreign Service of Pakistan (FSP)
• Inland Revenue Service (IRS)
• Pakistan Audit & Accounts Service (PAAS)
• Pakistan Customs Service
• and other federal services

Allocation depends on four factors together: your position on the final merit list, the preferences you submit, your domicile and quota, and the seats available in each group that year. This is why two candidates with similar marks and different domiciles can receive very different groups.

The regional quota

Seats are distributed under the quota framework notified by the Establishment Division on 19 August 2020:

Separate quotas exist for women and for minorities.

How many seats are actually available?

The number varies by cycle. FPSC announced 327 vacancies for CSS 2025. The CSS 2024 cycle had 364 seats, comprising 247 new vacancies and 117 carried forward from the previous cycle.

Fees

The written examination fee is paid through a 16-digit PSID via 1-Link banking channels.

Rechecking (recounting of marks)

A candidate who is unsatisfied with their result in a particular paper can apply to FPSC for rechecking, at a fee of Rs. 500 per paper. This is worth understanding correctly before you pay for it, because it is one of the most misunderstood parts of the whole process.

Rechecking is a recount, not a re-mark. FPSC's rechecking verifies that every attempted question was actually marked, that the marks awarded on each question were correctly totalled onto the answer sheet, and that the tabulated score was correctly transcribed to your result. It does not involve a different examiner reassessing the quality, argument, or content of your answers — the original marking judgement itself is not reopened.

In practice this means rechecking can catch a genuine arithmetic or transcription error, but it will not raise your score simply because you believe an answer deserved more marks than it received. Apply for it if you have a specific reason to suspect a counting or tabulation mistake — for example, your paper-wise marks don't add up to the total shown on your result — rather than as a general appeal against the mark itself.

Applications are made per paper, so if you want more than one paper rechecked, the fee applies separately to each. Check the current advertisement or FPSC's website for the exact application window for your cycle, since rechecking requests are typically only accepted within a limited period after the result is announced.

A typical cycle timeline

Using CSS 2026 as the worked example:

For calibration on the result gap: the CSS 2024 written result was released on 28 April 2025, more than a year after the written papers were taken. Build this waiting period into your planning — many candidates begin preparing for the next cycle while awaiting a result.

What the pass statistics tell you

Frequently asked questions

What is the CSS exam?

It is Pakistan's Central Superior Services competitive examination, conducted annually by the Federal Public Service Commission to recruit BPS-17 officers into twelve federal occupational groups and services.

How many papers are there in CSS?

Twelve — six compulsory papers of 100 marks each and optional papers totalling 600 marks, for a written total of 1,200 marks.

What is the total marks for CSS?

1,500 marks count toward final merit: 1,200 for the written examination and 300 for the viva voce.

Is the MPT part of the merit calculation?

No. The MPT is qualifying only, valid for that year's examination, and does not consume an attempt.

How many marks do I need to pass the written examination?

You need 40 per cent in each compulsory paper, 33 per cent in each optional paper, and a 50 per cent aggregate — 600 out of 1,200 — to be called for the viva voce.

How long does the whole CSS process take?

Ordinarily more than a year from the screening test to final allocation. The written result alone has historically taken from several months to over a year.

Does my domicile affect whether I can sit CSS?

No. Any eligible Pakistani citizen may appear. Domicile determines which regional quota your merit is assessed against at the allocation stage.
