RPF Sub Inspector is the graduate-entry officer route into the Railway Protection Force. The pattern mirrors RPF Constable, but the standard of questions is set to degree level and the pay is Level 6 rather than Level 3.

Cut offs are published as normalised marks scaled to 100, separately for male, female and ex-servicemen candidates within each category.

Qualifying marks

UR and EWS 35%, SC and ST 30%. PwBD candidates may receive a 2-mark relaxation where there is a shortage of PwBD candidates against reserved vacancies.

The CEN notes that listed topics are illustrative and not necessarily exhaustive.

Normalisation of marks

Where the CBT is held in multiple sessions on the same syllabus, shortlisting uses normalised marks rather than raw scores, so candidates who sat harder shifts are not disadvantaged.
