APSC Combined Competitive Exam 2026: ACS and Allied Services, Eligibility, Pattern, Syllabus and Preparation Guide

The Combined Competitive Examination (CCE) of the Assam Public Service Commission is the main door to senior civil service posts in the state. Successful candidates are placed in the Assam Civil Service (ACS) and in a group of allied services. For a graduate in Assam who wants a long administrative career, this is the exam that carries the most prestige inside the state, in the same way that the UPSC Civil Services Examination does at the national level.

This guide explains how the APSC CCE cycle works, what the syllabus looks like, how to prepare for the Assam-specific portion, and where candidates usually go wrong. A caution before you begin: the commission changes its advertisement from cycle to cycle. Post lists, age limits, fee, marks and even the mains subjects can differ. Use this article to understand the structure, and then confirm every number on the current official advertisement published by the commission (its website is apsc.nic.in).

How the Recruitment Cycle Works

The Assam Public Service Commission is a constitutional body under Articles 315 to 323 of the Constitution. The Chairman and members are appointed by the Governor. A member can be removed only by the President, after an inquiry by the Supreme Court finds misbehaviour, or on certain other grounds set out in Article 317. This design keeps recruitment away from ordinary political pressure. The commission is headquartered in Guwahati.

For the CCE, the cycle generally follows this order:

Stage	What happens
Advertisement	The commission publishes the list of services and posts, with the number of vacancies received from the government, for the cycle
Online application	Applications are submitted on the commission's portal, with photograph, signature and documents
Preliminary examination	An objective test held at centres across the state, used only to shortlist candidates for the next stage
Main examination	A written test with descriptive papers, held some months later
Interview (personality test)	A face-to-face interview before a board of the commission
Final merit list and allotment	Marks of mains and interview are combined, and services are allotted according to rank and preference

The gap between the preliminary and the main examination, and the gap between the main and the interview, are not fixed. In some cycles the whole process has run smoothly within a year. In others it has been stretched by court cases, revised results or administrative delay. This is why patient, long-term preparation works better than a rush after the advertisement appears.

Services Filled Through the CCE

The commission usually announces the services in the advertisement. In different cycles, posts have included the Assam Civil Service (Junior Grade and, in some cycles, Senior Grade), the Assam Police Service, the Assam Taxation Service, the Assam Finance and Accounts Service, and other allied posts such as those in cooperative societies, labour, taxation and block or circle level administration. Because the list changes, do not assume that a post you read about in a previous year is included. The advertisement is the only reliable source.

The ACS is the most sought-after service. An ACS officer usually begins as an Extra Assistant Commissioner or in a comparable post, handling revenue work, magistrate duties and district administration, and can later rise through the ranks to Additional Deputy Commissioner and eventually to the level of Commissioner and Secretary, with some officers getting inducted into the Indian Administrative Service through the promotion quota that exists for state civil service officers. The exact process and the number of such slots are decided by the central and state governments, so treat them as a possibility, not a promise.

Life in the Service

A young officer in Assam meets problems that are specific to the state. Flood management is an annual task, since each monsoon the Brahmaputra and its tributaries cause floods and erosion. Land matters, including the Assam Land and Revenue Regulation, 1886 and the protection of tribal belts, are part of everyday work. In tribal areas, Sixth Schedule councils such as Karbi Anglong, Dima Hasao and the Bodoland Territorial Council run their own systems, so officers work within dual administration. An aspirant who understands this writes better mains answers, because examiners like practical understanding of Assam and not only textbook theory.

Eligibility

Educational Qualification

A bachelor's degree from a recognised university is the usual requirement. Candidates in the final year of graduation are sometimes allowed to sit the preliminary stage but must produce the degree certificate by a date fixed in the advertisement. Some allied posts may ask for specific qualifications, for instance in accounts or law. Check post by post.

Age Limit

Assam has traditionally offered a higher upper age limit than many states, and CCE advertisements have generally set a minimum age of 21 years with an upper age limit in the late thirties for the unreserved category, with relaxation for reserved categories, persons with disabilities and government servants as notified. The cut-off date and the relaxation years appear in the advertisement. Do not rely on a coaching blog for these figures.

Domicile, Language and Category Rules

Recruitment to state services is generally aimed at Indian citizens who have a connection with Assam as set out in the rules, and reserved-category candidates need certificates issued by the competent authority in Assam. Categories used in Assam include General, Other Backward Classes and More Other Backward Classes (OBC and MOBC), Scheduled Castes, and Scheduled Tribes divided into ST (Plains) and ST (Hills). A candidate should keep the correct certificate ready in the prescribed format, because errors here are a common cause of rejection. Knowledge of Assamese, or of a recognised language of the state such as Bodo in the Bodoland area or Bengali in the Barak Valley, is usually tested through a language paper. Read the language-paper rule in the advertisement, since papers of this kind are often qualifying in nature, and the choice of languages is limited.

Application Process

1. Create a profile on the commission's portal with an active mobile number and email ID.
2. Complete the application with details exactly as in your certificates.
3. Upload a recent photograph, signature and any certificates asked for.
4. Pay the examination fee online. Fees differ by category and are set in the advertisement.
5. Take a printout of the confirmation and keep it safely.
6. Download the admit card when the commission releases it and note the reporting time.

Keep scanned copies of your HSLC certificate (for date of birth), degree certificate, category certificate and identity proof in one folder, so that you do not scramble after the advertisement.

Selection Stages in Detail

Preliminary examination. An objective paper based on general studies. It is for screening, so marks scored here do not count towards the final rank. The number of candidates called for the mains is usually a multiple of the vacancies, as decided in the advertisement.

Main examination. This is the decisive stage. It consists of descriptive papers. In recent structures these have included English, a language paper such as Assamese, an essay, and several general studies papers, and in some structures optional subjects. The language papers are often qualifying, meaning you must reach a minimum, but their marks may not count towards the final total. Check the scheme in the advertisement.

Interview. A personality test that evaluates knowledge of current affairs and Assam, clarity of thought, honesty and administrative understanding. Marks are added to the mains total for the merit list.

Verification and medical. Original documents are verified and a medical examination is held before appointment.

Exam Pattern: Typical Structure

The table below is a typical description. The exact number of papers, marks and time change across cycles, so treat it as an outline only.

Stage	Nature	Content
Preliminary	Objective multiple choice, screening only	General studies covering history, geography, polity, economy, science, current events, Assam, with some reasoning and comprehension
Main	Descriptive, written	English, a language paper, essay, general studies papers, and where notified, optional subject papers
Interview	Oral	Personality test before an interview board

Negative marking is commonly applied in the objective stage. Check the instructions on the admit card.

Detailed Syllabus and How to Study It

History of India and Assam

Cover ancient India, medieval India, and modern India up to Independence with stress on the freedom struggle. Then give a separate block of time to the history of Assam, because this is where a well-prepared local candidate can beat a candidate who has only read national books.

• Early Assam: the Kamarupa kingdom and the Varman dynasty, with Bhaskaravarman as its best-known king and the visit of the Chinese traveller Xuanzang in his time. Note the later rulers of Kamarupa, and the Koch kingdom with Naranarayan and his commander Chilarai.
• The Ahom period: the Ahom kingdom was founded by Sukaphaa, who entered the Brahmaputra valley in 1228. The dynasty ruled for almost six centuries. Study the paik system of organised labour, the Buranjis, which are Ahom chronicles, the capital shifts, the role of the Buragohain, Borgohain and Borpatra Gohain, and the wars with the Mughals. The Battle of Saraighat in 1671, in which Lachit Borphukan led the Ahom forces against a Mughal army under Ram Singh, is one of the most asked topics. Lachit Divas is observed on 24 November.
• Decline and British entry: the Moamoria rebellion, the Burmese invasions and the Treaty of Yandabo in 1826, which ended the First Anglo-Burmese War and brought Assam under British control. Then note the annexation of upper Assam, tea plantation history, Maniram Dewan and the revolt of 1857, the 1905 partition of Bengal and the place of Assam in it.
• Freedom movement in Assam: the role of Gopinath Bordoloi, Kanaklata Barua who was killed in 1942, Kushal Konwar, Ambikagiri Raichoudhury and Lakshminath Bezbaroa in literature and nationalism. Understand the Sylhet referendum of 1947 and the Cabinet Mission grouping issue, in which Bordoloi's opposition to grouping is remembered.
• After independence: the reorganisation of the old Assam into Nagaland, Meghalaya, Mizoram and other states, the Assam Movement led by the All Assam Students Union between 1979 and 1985, and the Assam Accord signed on 15 August 1985.

Culture, Religion, Literature and Art

Sankardeva, born in the fifteenth century, founded the Ekasarana Dharma and left a legacy of namghars, sattras, borgeets, Ankiya Nat and Bhaona. Madhavdeva was his chief disciple. Sattriya dance was recognised as one of the classical dances of India by the Sangeet Natak Akademi in 2000. Study Bihu (Bohag, Kati and Magh), the festivals of different communities such as Ali-Ai-Ligang of the Mising, Bwisagu or Baisagu of the Bodo, and Ambubachi at Kamakhya. Study writers such as Bezbaroa, Padmanath Gohain Baruah, Birendra Kumar Bhattacharya, Mamoni Raisom Goswami and Nabakanta Barua, and personalities such as Jyoti Prasad Agarwala and Bhupen Hazarika. Assamese was accepted as a classical language by the Government of India in October 2024, which is a good current-affairs and culture link.

Geography of India and Assam

For India, revise physical features, rivers, climate, resources and agriculture. For Assam, build a map-based understanding:

• The Brahmaputra valley, the Barak valley, and the hill districts of Karbi Anglong and Dima Hasao.
• The Brahmaputra and its major tributaries, including the Subansiri, Manas, Jia Bharali, Lohit, Dibang, Dhansiri and Kopili. Understand why the river floods, why it erodes, and what Majuli, the large river island, represents.
• National parks and sanctuaries: Kaziranga, Manas, Nameri, Orang, Dibru-Saikhowa and others, and the Hoollongapar Gibbon Sanctuary. Kaziranga and Manas are on the UNESCO World Heritage list.
• Resources: tea, oil and natural gas in upper Assam, with Digboi as the site of an old oil refinery, and forests and fisheries.

Indian Polity and Governance

The Constitution, Fundamental Rights, Directive Principles, Parliament, the President, the Governor, the judiciary, federalism, local government and constitutional bodies including the Public Service Commissions. Assam-specific pointers include the Sixth Schedule (Articles 244(2) and 275(1)), Article 371B for Assam, autonomous councils, the Assam Panchayat structure, the Assam Accord and the history of the citizenship register. If you use the Citizenship Act provisions related to the Assam Accord, read a reliable current source, because court decisions have changed the picture over time.

Economy

Indian economy basics, planning, budgeting, banking, inflation, GST and agriculture. For Assam, revise the state economy: the dominance of agriculture, the tea industry, the oil sector, small industry and handloom, the Bogibeel bridge near Dibrugarh, the Bhupen Hazarika Setu at Dhola-Sadiya, the Act East policy, and the flood-linked economic losses. Read the Economic Survey of Assam summary published with the state budget for current numbers.

General Science and Environment

School-level physics, chemistry and biology, health, and environment topics such as biodiversity, wetlands, climate change and river management. Assam's Deepor Beel wetland and the rhino conservation story of Kaziranga are natural examples.

Current Affairs

The last twelve to eighteen months, with special attention to Assam government schemes and policies, budget highlights, infrastructure projects, awards, sports and people. Schemes change often, so use the latest state government sources. Two names that have been discussed in recent years are the Orunodoi scheme for direct benefit transfer to women in households and the Nijut Moina scheme for girls' education, but do check their present status and amounts before writing about them.

Language, Essay and Comprehension

English comprehension, précis and grammar, and the language paper of your choice as permitted. For the essay, practise 800 to 1,000 word essays on subjects such as floods and development, the role of tea in the economy, education in the tribal belts, youth and unemployment, and the balance between conservation and infrastructure. Feedback from a teacher or friend matters more than volume.

Previous-Year Trends

A few patterns have appeared in different cycles, which you should treat as guidelines rather than promises:

• General studies papers have asked about Assam in each section: history, geography, culture, economy and polity. A candidate cannot skip Assam and still expect a good score.
• Current affairs from the past year, including Assam government programmes and national events, take up a significant share of the objective stage.
• In the mains, questions frequently connect national themes to Assam, for example flood management, migration, border issues, tribal autonomy, tea labour and infrastructure.
• The essay paper favours candidates who can give examples and structure their thoughts.

Cut-off marks are not given here, because they change with the paper and the number of vacancies. Use official result documents for such data.

Salary and Career Growth

Salary in the Assam government is set by the state pay structure under the Assam pay rules and dearness allowance decisions. The starting basic pay of ACS and allied Class I posts is notified with the appointment, and the total in hand depends on allowances. For reliable numbers, read the pay scale in the advertisement and the pay rules of the state government. Career growth in the ACS goes from Extra Assistant Commissioner to Additional Deputy Commissioner, then to Joint Secretary and beyond, with departmental promotions. Officers in the Assam Police Service and taxation services grow along their own ladder.

Model outline: (1) natural causes: monsoon, silt-heavy river, steep tributaries and earthquake-prone geology; (2) human factors: embankment failure, encroachment on wetlands, and deforestation upstream; (3) governance issues: coordination between states and countries on the river basin, and delays in relief; (4) responses: early warning, community-based preparedness, a river-basin approach and better land use; (5) conclusion: adaptation and flood-resilient livelihoods instead of one-time compensation.

Month-by-Month Preparation Plan (Ten Months)

A serious plan should last 8 to 12 months. A sample plan is given below.

• Months 1 and 2: Read NCERT-level books for history, geography, polity and economy. Start a daily newspaper habit and note Assam news separately. Begin an Assam notebook with sections for history, culture, geography, economy and schemes.
• Months 3 and 4: Move to standard books for each subject, and finish the first round of Assam history and geography with maps. Start a weekly essay and answer-writing habit.
• Months 5 and 6: Polity and economy in depth, science and environment. Take a sectional test every week.
• Month 7: Current affairs consolidation, revision of the Assam notebook, and the first full-length mocks for the preliminary stage.
• Month 8: Preliminary revision and test series. Focus on elimination techniques and time management.
• Months 9 and 10: After the prelims, shift to answer writing for the mains. Write at least three answers a day and one essay a week, and read government reports on Assam. Then prepare for the interview by giving mock interviews and reading your detailed application form, since questions will come from it.

Books and Resources

• NCERT textbooks from Class 6 to 12 for the base.
• A standard book on Indian polity, a book on Indian economy, and a reliable book on modern Indian history.
• A history and culture book on Assam from a recognised publisher, and the state's official publications, including the Economic Survey of Assam and the government's departmental websites.
• One Assam newspaper, one national paper and past question papers.
• Mock tests on pareeksha.in for regular practice of objective questions.

Common Mistakes

1. Treating Assam as a small section and studying it in the last month.
2. Reading too many books for a subject and revising none of them.
3. Not practising answer writing until the mains list is announced.
4. Ignoring the language paper because it is qualifying, and failing it.
5. Filling the application with errors in category, name or date of birth.
6. Using a previous year's scheme instead of reading the current advertisement.

Comparison with Other Assam Exams

Aspect	APSC CCE	ADRE Grade III	Assam Police SI	Assam Judicial Service
Conducting body	Public Service Commission	State recruitment under ADRE arrangement	State Level Police Recruitment Board	High Court
Qualification	Graduate	Class 12 (typically)	Graduate	Law degree
Nature	Prelims, mains, interview	Written test, other stages per post	Written, physical, other stages per notice	Prelims, mains, viva
Level	Highest	Moderate	Moderate to high	Specialised

If you want a job sooner and are not sure about the ACS, the ADRE Grade III exam is a practical step. If you prefer a uniformed career, see Assam Police Sub-Inspector. If you hold a law degree, look at Assam Judicial Service Grade III. Many CCE candidates keep a second exam in their plan, which is a sensible way to reduce risk.

Frequently Asked Questions

2. What are the stages? A preliminary objective test, a main written examination and an interview, followed by verification and allotment of services.

3. Do preliminary marks count in the final merit? Normally, no. The preliminary examination is a screening test. Confirm this in the advertisement.

4. Is knowledge of Assamese necessary? The language requirement is set in the advertisement. There is generally a language paper, and the acceptable languages are stated. Check it, since rules for candidates from different areas can differ.

5. Can graduates from any stream apply? For most posts, yes, with a graduation degree. Some posts can ask for special qualifications.

6. Is there negative marking? Objective tests typically carry it. Read the instructions on the admit card.

7. What are the age limits and fee? They are decided by the advertisement. Do not use figures from an earlier cycle.

8. Can I choose my service? Service allotment depends on your rank and the preferences you give, subject to vacancies and reservation rules.

9. How many attempts are allowed? Attempt limits, if any, are stated in the advertisement or the recruitment rules. Confirm before planning.

10. How much time should I give to preparation? Most serious candidates study for 8 to 12 months. A working candidate can succeed with a smaller daily commitment if the schedule is regular.
