CSS pass rules and merit guide
- Written examination: 1200 marks total — 600 compulsory (6 subjects × 100) and 600 optional.
- Per-subject pass: at least 40% in each compulsory subject and 33% in each optional subject.
- Written aggregate: at least 50% (600 / 1200) to move to the next stage.
- Interview (viva voce): 300 marks, at least 100 marks required to pass.
- Psychological assessment: qualifying only — no marks are added to the merit.
- Final merit: written 1200 + interview 300 = 1500 marks. As a rough guide only: 65% and above is strong, 60% to 65% is moderate and below 60% is borderline for allocation. The official FPSC result decides.

It changes every year with vacancies and competition. As a rough guide only, a final aggregate of 65 percent or above is strong and often competitive, while scores near 60 percent are borderline. This tool only estimates; the official FPSC result decides.
