Great news for all aspirants who appeared for the Intelligence Bureau Assistant Central Intelligence Officer (IB ACIO) Grade-II/Executive Phase 1 (Tier 1) examination! The Ministry of Home Affairs (MHA) has officially released the provisional answer key and response sheet today, September 22, 2025. This comes just days after the computer-based test concluded on September 18, 2025, allowing candidates to cross-check their answers and estimate their scores early.
The Tier 1 exam, held from September 16 to 18, 2025, for 3,717 vacancies, tested candidates on General Awareness, Quantitative Aptitude, Logical/Analytical Ability, and English Language. With the answer key now live, you can verify your responses, calculate your probable score using the marking scheme (+1 for correct answers, -0.25 for incorrect ones), and even raise objections if you spot any discrepancies.

Objections can be submitted online via the same portal by providing valid justifications and paying a nominal fee (details on the site). The objection period is typically short (check the notification for exact dates, likely ending around September 28-30, 2025), after which a final answer key will be released. Valid challenges may lead to score revisions, so act fast!
What’s Next After Phase 1?
Once objections are resolved, MHA will announce the Tier 1 results, shortlisting candidates for Phase 2 (Descriptive Test) and subsequent interview rounds. Qualifying the full process lands you in one of India’s most prestigious intelligence roles—stay prepared!
