RRB ALP Answer Key 2026: CBT 1 Response Sheet, Objections and Score Calculation

RRB ALP Answer Key 2026 for CBT 1 was released on 20 March 2026 at 5 PM, under CEN 01/2025. Candidates who sat the exam on 13, 16, 17, 18 February and the re-exam on 11 March 2026 could log in and check their response sheet against the provisional key before the objection window closed on 26 March 2026. This page covers the release details, the objection process, the marks formula, and how this answer key fed into the RRB ALP result that followed.

RRB ALP Answer Key 2026: Release Date and Portal

RRB released the provisional CBT 1 answer key on 20 March 2026 at 5 PM, roughly five weeks after the last exam date. The answer key, question paper, and each candidate's own response sheet were made available together on rrb.digialm.com, the candidate login portal RRB uses for this recruitment. This is a separate system from rrbapply.gov.in, which handles the online application rather than post-exam documents, so candidates should not expect to find the answer key on the application portal.

RRB ALP Answer Key 2026 Objection Window and Fee

The objection window ran from 20 March 2026 at 5 PM to 26 March 2026 at 5 PM, with no extensions granted after the deadline. Raising an objection cost Rs. 50 per question, refundable if RRB accepted the challenge, and required supporting justification or reference material rather than a plain disagreement with the listed answer. Candidates who skipped this window could not challenge the same answer key later, whatever their CBT 1 score turned out to be.

How to Calculate RRB ALP Marks Using the Answer Key

A candidate can estimate their CBT 1 score directly from the response sheet and answer key using the same formula RRB applies for scoring.

RRB ALP CBT 1 Marks = (Number of Correct Answers x 1) minus (Number of Incorrect Answers x 1/3)

Unattempted questions are left out of the calculation entirely, they neither add nor subtract from the total. This estimate is useful for gauging where a candidate stands against the qualifying percentage below, though it will not exactly match the final normalised score RRB uses for the zone-wise cut off.

RRB ALP 2026 Qualifying Marks

The answer key is only useful for self-scoring if a candidate also knows the minimum percentage needed to qualify. These are fixed by category and applied to the normalised CBT 1 score, not the raw count from the formula above.

Ex-servicemen are assessed against the slab for their original category, not a separate fixed percentage.

What the RRB ALP Answer Key 2026 PDF Shows

The response sheet and answer key together carry more than just correct answers, and it is worth checking every field before deciding whether to raise an objection.

• Candidate's name and registration number
• Exam date and shift
• RRB zone
• Question ID for every question in the paper
• The full question paper as it appeared to that candidate
• The candidate's selected response for each question
• The official answer as per the provisional key
• Status of each question: correct, incorrect, or unattempted
• Section-wise breakdown of questions
• Instructions for filing an objection

RRB ALP Answer Key 2026: What Happened Next

Once the objection window closed on 26 March 2026, RRB reviewed the challenges internally and folded any accepted corrections into the scoring rather than publishing a separate revised key. The CBT 1 result, incorporating those corrections, was declared on 12 June 2026, with the roll numbers of shortlisted candidates released zone-wise. A candidate's self-calculated score from this answer key was a reasonable early estimate, but the result PDF and scorecard are what actually confirm qualifying status.
