SSC Selection Post recruits for specific posts advertised by various ministries and departments on an ad-hoc basis. Unlike CGL or CHSL, vacancies and educational requirements vary each phase. The exam has 3 levels: Matric, Higher Secondary, and Graduate.

All three levels (Matric, Higher Secondary, Graduate) follow the same pattern: 100 MCQs in 60 minutes. Each section has 25 questions from General Intelligence, Quantitative Aptitude, English, and General Awareness. Marking: +2/-0.5.

SSC Selection Post Phase XII notifies various posts like Laboratory Assistant, Junior Chemist, Pharmacist, Research Assistant, Statistical Assistant, and other technical/non-technical posts from various government departments.

SSC Selection Post Phase XII is expected to have 2,000-4,000 vacancies. Previous phases had varying counts: Phase XI had 3,447 vacancies while Phase X had 1,411 vacancies across Matric, Higher Secondary, and Graduate levels.

Some posts under SSC Selection Post require additional tests like Skill Test, Typing Test, or Document Verification depending on the nature of the post. This is specified in the individual post notification. Most posts are direct merit-based selection.
