Frequently asked questions
SI or constable — which should I target?
If you have or are completing a degree, target SI: better pay, authority and promotion ceiling. Constable is the earlier entry with promotion routes.

Can women join the police?
Yes — states recruit women constables and SIs, often with slightly different physical standards and dedicated women's police stations.
State police or central forces (CRPF/BSF)?
Both are uniformed careers; central forces follow central pay and posting across India, state police serve within the state's cadres. Compare notifications honestly.
