Sikkim PCS refers to the Sikkim Public Service Commission (SPSC) examinations, which are state-level competitive exams conducted by the Sikkim Public Service Commission (official website: https://spsc.sikkim.gov.in/  & www.onlycompetition.com) for recruiting candidates to various Group A & B administrative posts in the Government of Sikkim.

It is commonly called Sikkim PCS (similar to UPPCS, MPPCS, etc.), but the official term is Sikkim State Civil Services Examination or Combined Recruitment Examinations (CRE) for posts like:

• Under Secretary (Junior Grade) under Sikkim State Civil Services
• Accounts Officer
• Other posts: Assistant Engineer, Sub-Inspector, Block Officer, etc.

These exams are the gateway to prestigious state government jobs in Sikkim, similar to UPSC for central services but focused on state-level administration.

Key Features of Sikkim PCS (SPSC Exams) www.onlycompetition.com

• Conducting Body: Sikkim Public Service Commission (Gangtok-based constitutional body under Article 315 of the Constitution).

• Heavy Focus on Sikkim: 30–50% questions revolve around Sikkim-specific GK (history, geography, culture, economy, schemes, tribes, organic farming, hydropower, tourism, border issues with China, etc.). This is the biggest differentiator from UPSC or other PCS exams.
