CHO exam preparation is different from a regular staff nurse exam: the paper is built around primary health care, the Certificate in Community Health (CCH) curriculum and National Health Mission programmes, and in states like Rajasthan it also tests general knowledge, language and computers. This guide gives you a complete, phase-wise plan for CHO exam preparation for Rajasthan, UP, MP, Bihar and other state NHM recruitments, with timetables for full-time aspirants and working nurses.

Who should read this guide
This plan is for B.Sc Nursing, Post Basic B.Sc Nursing and GNM candidates (and BAMS candidates in states that allow them) who want a Community Health Officer post at an Ayushman Arogya Mandir (formerly Health and Wellness Centre). It suits fresh graduates starting from zero, nurses who already cleared a CCH bridge course, and working nurses who can give only two to three hours a day.
Eligibility differs by state. For example, Rajasthan’s 2025 cycle accepted B.Sc Community Health, GNM, B.Sc Nursing or BAMS with state registration, while UP’s 2024 cycle asked for B.Sc or Post Basic B.Sc Nursing with integrated CCH. Always read your state notice first. Our CHO notification 2026 hub tracks the latest verified status for each state.
CHO exam overview in brief
Every state writes its own paper, but the core is the same: questions on community health nursing, maternal and child health, family planning, communicable and non-communicable diseases, nutrition, national health programmes, primary care skills and basic pharmacology. Some states add a general section. In Rajasthan’s 2025 RSSB exam, coverage reported a 150-question, 450-mark paper with general knowledge, Hindi and English, NHM and RMNCH+A, computer knowledge and a large professional section.
For the full state-wise structure, marking scheme and syllabus, read the CHO exam pattern and syllabus guide before you start this plan, because the weightage decides where your hours should go.
6-month CHO exam preparation plan
Six months is a comfortable window for a fresh graduate. If you have only three months, merge Phase 1 and Phase 2 and start mock tests from week four.
| Phase | Duration | Focus | Output by the end |
|---|---|---|---|
| Phase 1: Foundation | Month 1 to 2 | Community health nursing, epidemiology basics, MCH, family planning, nutrition, anatomy and physiology basics | Own short notes for each topic, 30 to 50 MCQs a day |
| Phase 2: Programmes and clinical primary care | Month 3 to 4 | National health programmes, NHM structure, RMNCH+A, immunisation schedule, communicable and NCDs, first aid, emergencies, common drugs | Programme tables, drug list, first topic-wise tests |
| Phase 3: Practice and state section | Month 5 | Previous year papers, state GK, Hindi and English, computers (for Rajasthan and similar states), weekly full-length mocks | Error notebook, list of weak areas |
| Phase 4: Revision | Month 6 | Two to three full revisions, daily mocks, current health news | Exam-ready speed and accuracy |
Subject priority
Spend the most time where the CHO job itself sits: community health and primary care. A practical order of priority is:
- Community health nursing and epidemiology: levels of prevention, health care delivery in India, sub-centre to district level, roles of the CHO, ASHA and MPW, health indicators.
- Maternal, newborn and child health: antenatal care, high-risk pregnancy, postnatal care, newborn care, IMNCI, growth monitoring, breastfeeding.
- National health programmes and NHM: immunisation (UIP), RMNCH+A, TB elimination, malaria and vector-borne diseases, NCD screening, Anaemia Mukt Bharat, family planning methods.
- Communicable and non-communicable diseases: agent, mode of spread, incubation period, prevention and treatment protocols.
- Nutrition: deficiency disorders, RDA concepts, supplementary nutrition schemes.
- Primary care skills: first aid, triage, management of minor ailments, wound care, emergencies and referral.
- Basic pharmacology: essential medicines at the health centre level, drug classes, common doses taught in the CCH curriculum.
- State general section (if your state has one): state GK, language and computers.
Use our community health nursing notes and national health programmes notes as your base material for the top three priorities.
Daily timetable for CHO aspirants
Full-time aspirant (8 to 9 hours)
| Time | Task |
|---|---|
| 6:00 to 8:00 am | New topic from the high-priority list (reading and short notes) |
| 8:30 to 10:30 am | Second topic, preferably a programme or MCH chapter |
| 11:00 am to 12:30 pm | 50 to 75 topic-wise MCQs and error analysis |
| 2:00 to 3:30 pm | Revision of the previous day’s topics |
| 4:00 to 5:00 pm | State GK, language or computers (if part of your state paper) |
| 6:00 to 7:30 pm | Live class or recorded lecture |
| 8:30 to 9:30 pm | Quick revision of the day plus 20 PYQs |
Working nurse (2.5 to 3 hours)
| Time | Task |
|---|---|
| 45 minutes before duty | One focused topic from your notes |
| Travel or break time | Flash revision of tables (immunisation, incubation periods, drug list) on the app |
| 1 hour after duty | 30 to 40 MCQs and error notebook |
| Weekly off day | One full-length mock test plus four hours of revision |
Working nurses have an advantage: ward and OPD experience helps with clinical and skill-based questions. Link what you see at work to the protocol you read.
Best books and sources for CHO exam preparation
Keep your resources few and revise them many times. These are widely used, standard sources:
- Park’s Textbook of Preventive and Social Medicine by K. Park: the reference for epidemiology, communicable diseases, nutrition and programmes. Read selectively.
- Essentials of Community Health Nursing by K. Park, or Community Health Nursing: Principles and Practices by K.K. Gulani: easier language for nursing students.
- IGNOU Certificate in Community Health (CCH) study material: the curriculum on which many CHO papers and bridge courses are based.
- Textbook of Obstetrics by D.C. Dutta: for antenatal, intranatal and postnatal care basics.
- Ministry of Health and Family Welfare guidelines: operational guidelines for Ayushman Arogya Mandir, immunisation and programme guidelines, available on official websites.
- A standard general knowledge book and a state GK source, only if your state paper has a general section.
- Exam-focused books: our CHO books condense the above into exam-oriented notes and MCQs.
How to use mock tests and previous year papers
Start topic-wise tests in month two and full-length mocks in month four or five. A mock is only useful if you analyse it: spend at least as long reviewing a test as you spent writing it.
- Error notebook: write every wrong or guessed question as a one-line fact. Revise this notebook every Sunday.
- Negative marking practice: several state CHO papers deduct marks for wrong answers. Track your accuracy and stop guessing blindly when two options still look correct.
- Previous year papers: solve at least the last three to four years of your state and one or two neighbouring states. CHO papers repeat concepts (immunisation, danger signs in pregnancy and newborns, programme targets, NCD screening ages) far more than they repeat exact questions.
- Timing: practise at the same time of day as your actual exam slot.
The Concept RNA CHO test series is built for state CHO exams, and our free test series is a good starting point to check your level.
Revision method
Use a 1-7-30 rule: revise a topic the next day, again after a week and again after a month. Convert long chapters into one-page tables: immunisation schedule, diseases with incubation periods, vitamins and deficiency diseases, family planning methods with failure facts, and programme launch years. In the last month you should be revising only these pages and your error notebook.
Common mistakes to avoid
- Reading only staff nurse material and ignoring programmes, NHM and primary care, which are the heart of the CHO paper.
- Skipping the general section in states like Rajasthan, where it carries real marks.
- Collecting too many PDFs instead of revising one set of notes.
- Learning outdated programme names and targets. Use the current names (for example, Ayushman Arogya Mandir) and check guidelines on official sites.
- Taking mocks without analysing them.
Habits of successful CHO aspirants
- They fix a daily MCQ target and never skip it, even on busy duty days.
- They make their own tables instead of copying full chapters.
- They read health news and new programme launches weekly.
- They revise more than they read new material after month four.
- They keep track of their state’s official notice instead of relying on rumours.
Last 30 days plan and exam-day tips
| Days | Plan |
|---|---|
| Day 30 to 21 | First full revision of all high-priority subjects, one mock every alternate day |
| Day 20 to 11 | Second revision, PYQs of your state, daily mock, state GK and computers |
| Day 10 to 4 | Only short notes, tables and error notebook, one mock a day at exam timing |
| Day 3 to 1 | Light revision of tables, no new topics, sleep on time, check admit card and centre |
Exam-day tips
- Carry the admit card, a valid original photo ID and anything else the admit card lists; reach the centre early.
- In the first pass, attempt only questions you are sure about. Come back for the rest.
- Read negative words carefully (“except”, “not”, “contraindicated”).
- If your paper uses an OMR sheet, fill bubbles as you go, not all at the end.
- Follow the official instructions on unattempted questions; some state boards have specific rules on this.
Frequently asked questions
How many months are enough for CHO exam preparation?
Most nursing graduates need four to six months of steady study. If you recently completed B.Sc Nursing with integrated CCH, three months of focused practice on programmes, PYQs and mocks can be enough.
Is Park’s textbook necessary for the CHO exam?
It is the most trusted reference for preventive and social medicine, but you do not need to read it cover to cover. Use it for epidemiology, communicable diseases, nutrition and programmes, and rely on concise notes for revision.
Can a working nurse crack the CHO exam?
Yes. With two and a half to three hours a day, a fixed MCQ target and one full mock on the weekly off, working nurses can prepare well. Clinical experience also helps with skill-based questions.
Is the CHO syllabus the same in all states?
The professional core (community health, MCH, programmes, primary care) is similar, but the paper structure, general sections and marking differ by state. Check the CHO exam pattern guide and your state notice.
Which course should I join for Rajasthan CHO?
Choose a course that covers both the professional section and the Rajasthan general section. Our Rajasthan CHO course is designed for the RSSB pattern, and other state batches are listed under CHO courses.
