IB ACIO 2026: Intelligence Bureau Assistant Officer Grade II

IB ACIO 2026: Assistant Central Intelligence Officer Grade II recruitment

The Intelligence Bureau (IB), India's internal intelligence agency under the Ministry of Home Affairs, conducts the Assistant Central Intelligence Officer (ACIO) Grade II Executive recruitment once every one to two years. The 2026 notification is expected in November or December 2026 with the Tier 1 exam in January or February 2027. The 2024-25 cycle offered 995 vacancies with about 15 lakh applications, giving a selection ratio near 1:1,500. It remains one of the most competitive Grade-B non-gazetted central government roles for graduates.

An ACIO Grade II is the entry-level intelligence officer inside IB. Posting is anywhere in India, including field intelligence units, sensitive border zones, state IB offices, and later foreign assignments as an intelligence liaison. Pay starts at Level 7 (Rs. 44,900 basic) plus a Special Security Allowance of 20% of basic pay unique to IB officers. Total gross runs Rs. 65,000 to Rs. 80,000 in-hand depending on posting city and allowances.

Important dates for IB ACIO 2026

Dates below are the expected schedule based on the 2022 and 2024-25 recruitment cycles. Confirm every date against mha.gov.in once the official notification is released.

What an IB ACIO Grade II Executive does

An Assistant Central Intelligence Officer Grade II is a field-and-desk intelligence officer inside the Intelligence Bureau. Work covers three broad areas: internal security intelligence, counter-intelligence, and threat analysis. Typical duties for a new ACIO in the first three years:

• Source development and human intelligence collection in the assigned sector
• Surveillance and covert observation of persons of interest
• Report writing for supervisory desks (subsector, sector, regional office)
• Coordination with state police special branches and central armed police forces
• Verification-related work for sensitive central government appointments
• Desk analysis of communications, open-source intelligence, and technical inputs

Posting is anywhere in India. New recruits usually start at a subsidiary intelligence unit or a state IB office rather than IB headquarters in Delhi. Rotational transfers are common. Foreign postings as an intelligence liaison at Indian missions abroad open up from ACIO Grade I onwards.

IB ACIO 2026 selection process

Selection has three tiers. All three tiers must be cleared to make it to the final merit list.

Tier 1 (objective, 100 marks, 1 hour)

There is negative marking of 0.25 for each wrong answer. Duration is 60 minutes. Tier 1 cutoffs in recent cycles ran around 85 to 90 marks out of 100 for UR category, meaning candidates typically need 85+ correct answers out of 100. That is a very high bar and puts IB ACIO Tier 1 among the toughest single-hour objective papers in Indian recruitment exams.

Tier 2 (descriptive, 50 marks, 1 hour)

Two descriptive tasks:

• Essay in English on a given topic (30 marks). Typical topics: national security, counter-terrorism strategy, cyber warfare, internal security challenges, refugee crisis, India's foreign policy, or a current affairs topic.
• English comprehension and precis writing (20 marks). One passage with a summary task.

There is a minimum qualifying threshold of 33% (17 marks). Only candidates who cross both the Tier 1 cutoff and the Tier 2 qualifying line are called for Tier 3.

Tier 3 (personality test and interview, 100 marks)

Held in Delhi at IB headquarters or a regional IB office. Panel typically has 5 members drawn from serving IB officers of Deputy Director rank and above, plus one external representative.

Focus areas in the interview:

• Reason for choosing IB over SSC CGL, banking, or other central government roles
• Understanding of the internal security profile of your home state (insurgency history, current threat groups, sensitive districts)
• Awareness of current geopolitical events affecting India
• Personality traits (composure under pressure, discretion, integrity)
• Language skills, especially in a second Indian regional language

Final merit is the sum of Tier 1 (100) + Tier 2 (50) + Tier 3 (100) = 250 marks total. Weightage is roughly 40% Tier 1, 20% Tier 2, 40% Tier 3. This means the interview can swing the merit list heavily.

After the final merit list, selected candidates undergo a document verification round, a medical examination, and a comprehensive background check (which can take 3 to 6 months and involves police verification at every past residence).

IB ACIO Grade II salary and perks

Entry pay is at Level 7 of the 7th CPC Pay Matrix.

• Basic pay: Rs. 44,900
• Special Security Allowance: 20% of basic (Rs. 8,980). This is unique to IB.
• Dearness Allowance: current DA rate applied on basic
• House Rent Allowance: 8%, 16%, or 24% depending on city category
• Transport Allowance: as per city category
• Deputation allowance if posted on deputation elsewhere

Approximate monthly gross for a fresh recruit posted to a Class X city (Delhi, Mumbai, Bengaluru): Rs. 78,000 to Rs. 85,000. In a Class Y city: Rs. 68,000 to Rs. 72,000. Net in-hand is Rs. 55,000 to Rs. 65,000 after NPS, income tax, and mandatory deductions.

Non-monetary perks include: government-provided accommodation at concessional rent or an HRA in lieu, CGHS medical for self and family, LTC (leave travel concession) every four years, official vehicle for field duty, and post-retirement pension under NPS with 14% government contribution.

Career progression inside IB

The IB cadre structure for ACIO Grade II Executive:

Promotion from ACIO Grade II to ACIO Grade I is typically time-bound after 4 years of satisfactory service. Beyond ACIO Grade I, promotion is selective and depends on vigilance clearance, annual performance appraisal, and specific vacancies at the higher level. A committed officer usually reaches Deputy Director (Level 12) by year 20 of service. Reaching Joint Director and above (Level 13+) is competitive because posts at those levels are limited.

Foreign posting opportunities as an intelligence attache at Indian missions abroad (usually consulates, sometimes embassies) open up from ACIO Grade I onwards and are considered career-defining tours.

Preparation strategy for IB ACIO 2026

Timeline for a graduate starting from scratch

For a graduate starting preparation in July 2026 for a Tier 1 exam in January or February 2027, a 6 to 7 month plan works:

• Months 1 to 2: Static General Studies (Constitution, geography, economy fundamentals) plus daily current affairs from The Hindu or Indian Express. Basic quantitative aptitude (arithmetic, DI, algebra) and English grammar.
• Months 3 to 4: Reasoning practice, advanced GS (internal security, defence, science and tech), current affairs consolidation. First full-length mock test in month 4.
• Month 5: Sectional and full-length mocks, 3 to 4 per week. Analyse each mock; identify weak topic and drill for 2 hours before the next mock.
• Month 6: Tier 2 essay writing practice (2 essays per week on internal security, foreign policy, or current affairs topics), precis writing daily.

Post Tier 1 clearance, spend 6 to 8 weeks on Tier 2 essay and precis, and start interview preparation in parallel because the Tier 3 window opens quickly after Tier 2 result.

Section-wise book recommendations

• General Studies (static + current): Lucent's General Knowledge, Laxmikant's Indian Polity, NCERT class 6 to 12 Geography and Economics, monthly current affairs digest.
• Quantitative Aptitude: R.S. Aggarwal Quantitative Aptitude for Competitive Examinations, Arun Sharma Quant for CAT for advanced problems.
• Reasoning: R.S. Aggarwal Verbal and Non-Verbal Reasoning, M.K. Pandey Analytical Reasoning.
• English: Wren and Martin High School English Grammar, Norman Lewis Word Power Made Easy for vocabulary.
• Internal Security and India-specific GS: Ashok Kumar and Vipul Anekant "Challenges to Internal Security of India", plus IDSA policy briefs available free at idsa.in.

Tier 2 essay preparation

Read three to four essays per week from Hindu editorials, Indian Express opinion pages, and IDSA commentaries. Practice writing one 250-word essay per week under 30 minutes strict timing. Target topics: cybersecurity in India, cross-border terrorism, radicalisation and de-radicalisation, refugee policy, technology and intelligence, and India's neighbourhood policy. Essays are scored on structure (introduction, body, conclusion), argument quality, factual accuracy, and language clarity.

Interview preparation

Focus on three areas:

• Home state internal security profile (know the insurgency history, current threat groups, sensitive districts, and inter-community dynamics of your state)
• India's border situation (LAC, LOC, western border, northeastern border) at a factual level
• Recent government initiatives you can name and briefly explain (e.g., NATGRID, CCTNS, CMS interception system, Multi-Agency Centre)

Mock interviews with peers or coaching institutes (Delhi has 4 to 5 that specialise in IB ACIO interviews) are useful for pressure-testing composure.

IB ACIO vs SSC CGL vs CAPF Assistant Commandant

Since most IB ACIO candidates also consider SSC CGL and CAPF AC, a direct comparison:

The choice depends on what a candidate wants. IB ACIO trades a physical entry test for a much higher intellectual and personality bar in the interview, plus a career that keeps you away from public attention. CAPF Assistant Commandant offers a higher starting pay level and Group A status but demands field service in tough terrain. SSC CGL is easier to crack and offers a stable civilian career but limited exposure to sensitive national security work.

Common mistakes IB ACIO aspirants make

• Underestimating the Tier 1 cutoff. 85+ out of 100 is a very high bar. Many candidates prepare like SSC CGL Tier 1 (65 to 70 target) and fall short.
• Ignoring the Tier 2 minimum qualifying rule. A high Tier 1 score does not save a candidate who scores below 17 marks in Tier 2.
• Weak interview prep on home state internal security. Panels test this heavily. A candidate from Bihar who cannot discuss Naxal-affected districts of Bihar loses ground.
• Applying for centre preferences without research. Getting Delhi as first choice is rare unless your home address is in NCR. Realistic second and third choices matter.
• Skipping the background check preparation. Verification covers every past residence for the last 10 years. Discrepancies in address history or gaps in college attendance surface and delay appointment.
• Preparing only through coaching modules for Tier 2. Coaching material is repetitive across candidates. Original reading from The Hindu, Indian Express, and IDSA gives Tier 2 essays the edge they need.

Frequently asked questions

When will the IB ACIO 2026 notification be released? The 2026 notification is expected in November or December 2026 with Tier 1 in January or February 2027. Watch mha.gov.in during that window. IB does not maintain a separate recruitment portal.

Is there negative marking in IB ACIO Tier 1? Yes. 0.25 marks are deducted for every wrong answer in Tier 1. Unattempted questions carry no penalty. This makes conservative marking (attempt only if 70% sure) important.

What is the minimum score to clear IB ACIO Tier 1? Historical cutoffs: UR around 85 to 90 out of 100, OBC around 80 to 85, SC and ST around 70 to 78. Cutoffs vary each cycle based on paper difficulty and candidate pool.

Does IB ACIO have a physical test or medical exam? No physical efficiency test. There is a standard medical examination after final selection to confirm fitness for field intelligence duty. Vision, hearing, and general physical health are checked.

Can final-year graduation students apply for IB ACIO 2026? No. The Bachelor's degree must be completed by the last date of application. Provisional applications from final-year students are not accepted.

What is the total salary of an IB ACIO Grade II Executive? Monthly gross runs Rs. 68,000 to Rs. 85,000 depending on city category, with the Special Security Allowance adding 20% of basic. Net in-hand after NPS, tax, and other deductions is Rs. 55,000 to Rs. 65,000.

How long does the background check take before joining IB? Between 3 and 6 months. Verification covers police records, address history for the last 10 years, family antecedents, financial background, and character references. Any discrepancy triggers re-verification and delays joining.

Are foreign postings available in IB? Yes, but not at the ACIO Grade II level. Foreign postings as intelligence liaisons at Indian missions abroad open up from ACIO Grade I onwards (typically after 4 to 6 years of service).

Can I apply for IB ACIO along with SSC CGL and other exams? Yes. The exam calendars for IB ACIO, SSC CGL, and Banking exams (IBPS, SBI PO) generally do not clash. Many candidates prepare for multiple exams in parallel; the syllabus overlap for General Studies and quantitative aptitude is high.

How difficult is the IB ACIO interview compared to UPSC CSE interview? Different rather than harder. UPSC CSE interviews test general awareness broadly. IB ACIO interviews go deep into internal security, your home state's threat profile, and personality traits suited to discretion-heavy work. A candidate who has read The Hindu editorial page and IDSA briefs for 3 months does better than one who has crammed generic current affairs.
