The CSS examination is a sequence, not one event. MPT opens the gate; written papers create the merit base; medical, psychological and viva stages determine final suitability and allocation. For eligibility, subjects, dates and the full application process, see the complete CSS exam in Pakistan guide.
What the exam recruits for
FPSC uses the competitive examination to recruit officers for federal occupational groups. The process tests knowledge, written judgment, communication, psychological suitability and readiness for public responsibility.
The five stages of the examination
Each stage changes the kind of preparation required. The useful move is to know the whole sequence while focusing daily work on the next assessed stage.
Written examination: 1,200 marks
Six compulsory papers contribute 600 marks. Candidates then select optional subjects contributing another 600 marks under the official group rules. English performance and analytical answer quality influence the whole written stage.
Essay, Precis, GSA, Current Affairs, Pakistan Affairs and Islamic Studies.
A valid combination selected from seven subject groups.
From written result to final merit
Candidates who clear the written stage proceed through medical and psychological assessment to viva voce. Final merit combines written and viva marks, while allocation also depends on preferences, suitability, vacancies and quota rules. Allocation to an occupational group also sets the starting salary, allowances and career progression that follow.
How CSS group selection works
Group selection happens through a preference ranking, not a direct application to a single service. When completing the written-exam application, candidates rank all 12 occupational groups — Pakistan Administrative Service, Foreign Service of Pakistan, Police Service of Pakistan and the rest — in order of preference. FPSC then allocates each successful candidate to a group using merit position, stated preferences, domicile-linked provincial quota, and the number of vacancies FPSC has notified for that group that year. A strong merit position widens a candidate's realistic options but does not override quota and vacancy limits, which is why some highly-ranked candidates still miss their first-preference group in a competitive year. For a full breakdown of every group and what each role involves, see what a CSS officer does across the 12 occupational groups.
Quick structural questions
MPT is a qualifying screening stage. Final merit is built from the marks FPSC designates for the competitive written examination and viva.
The written stage contains twelve papers: six compulsory papers and a valid optional combination totaling 600 marks.
No. Group limits control how many marks may be selected from each group, so candidates normally build a combination across groups.
Candidates rank the 12 occupational groups by preference when completing their written application. After final merit is calculated, FPSC allocates each candidate to a group based on merit position, stated preferences, domicile-linked quota, and available vacancies — a higher merit position improves the odds of receiving a top preference, but does not guarantee it.
