UPSC and State Public Service Commissions share a common goal of selecting candidates for public service roles, yet differ in scope and structure. While the UPSC handles central government examinations, State Commissions focus on state-level positions. The syllabus may overlap but varies in certain topics specific to each state's governance and policies. Additionally, UPSC conducts a single examination cycle for multiple services, whereas State Commissions manage independent recruitment processes, including different eligibility criteria and examination patterns.
