RRB Isolated Categories Recruitment 2026

One CBT for every post

There's a single computer-based test. Half of it is on your own subject.

RRB says the split is indicative and the actual paper can vary a little. Marks are normalised if the CBT runs in more than one shift.

Minimum marks to qualify: UR and EWS 40%, OBC (NCL) and SC 30%, ST 25%. PwBD candidates can get 2 marks of relaxation if there aren't enough of them for their reserved posts.

Junior Translator is different

The paper tests English and Hindi equally. 30 questions are on Hindi and 20 on English, and these 50 aren't translated: Hindi questions come only in Hindi, English ones only in English. The other 50 cover general knowledge, reasoning, simple arithmetic and computer basics. The language part is set at 12th standard.

After the CBT, 10 times the number of vacancies (category-wise) are called for a translation test. You need 60% to pass it, but it's only qualifying. Your merit rank comes from the CBT marks alone.

After the CBT

RRB calls candidates equal to the number of vacancies in each RRB (1:1) for document verification and the medical, based on CBT merit and the posts you opted for. If two people have the same marks, the older one ranks higher. If the age is also the same, it goes by the alphabetical order of the first name.
