CV Raman Global University (CGU) is a private university in Bhubaneswar, Odisha—recognized by UGC under Section 2(f) of the UGC Act, 1956. The Kerala Public Service Commission (KPSC) is a Kerala-state body recruiting for Kerala government jobs.
Indian public service commissions (UPSC, state PSCs) don't "approve" universities. They set eligibility criteria for their exams: typically, a degree from a UGC-recognized university (central, state, private, deemed) or equivalent. CGU's UGC recognition meets that baseline.
If you're a CGU graduate applying for KPSC exams: verify your specific program's statutory council approval (AICTE, NCTE, etc.). Contact KPSC directly or check their notification's "educational qualification" clause. "KPSC approval of university" is a category error—it doesn't exist.
