If you have a B.E./B.Tech, an M.Sc., a law degree, or a professional certificate like CA or CMA and you are looking at Tamil Nadu government jobs, TNPSC Combined Technical Services (Non-Interview) is probably already on your radar. It is one of the few TNPSC exams where you don't have to sit through an interview to get a government job — you clear the written papers, get verified, and you're in.
This year's cycle is live right now. The notification came out in May 2026, applications closed in June, and the written exam is scheduled to start in mid-August 2026. If you're reading this before the exam, you still have a few days to sharpen your prep. If you're reading this for the next cycle, everything here still applies almost exactly the same way, since TNPSC keeps the CTS pattern fairly stable year to year.
Latest notification and important dates
TNPSC released the Combined Technical Services (Non-Interview Posts) 2026 notification on 20 May 2026. The vacancy count was revised upward twice through addendums — it started at 461, went to 476, and the latest addendum (4A/4B) pushed it to 508 posts. Always check the addendum section on tnpsc.gov.in before you assume a number, because TNPSC keeps adjusting these until close to the exam.
| Event | Date |
|---|---|
| Notification released | 20 May 2026 |
| Online application starts | 27 May 2026 |
| Last date to apply online | 25 June 2026 (11:59 PM) |
| Correction window | 29 June – 1 July 2026 |
| Hall ticket release | Last week of July 2026 |
| Written exam (Paper I & II) | 16 August 2026 onward (tentative, spread across dates depending on post) |
| Result / cut-off | To be announced after exam |
Note: because CTS covers 45 different technical posts, TNPSC doesn't hold every paper on a single day. The exam is spread over a schedule from mid-August into September, and your exact date and shift show up on your hall ticket. Don't assume your neighbour's exam date is yours.
For live updates, keep checking Pareeksha's exam news section and the official site tnpsc.gov.in.
What the job actually is
CTS is not one job, it's a bundle of 45 different technical and scientific posts spread across various Tamil Nadu government departments and boards. You could end up as an Assistant Engineer in the Rural Development department building roads and check dams, a Junior Scientific Officer in the Forensic Science department analysing evidence for criminal cases, a Block Health Statistician compiling public health data for a district, a Drug Inspector checking pharmacy licenses and drug quality, or a Geologist, Environmental Scientist, Archaeologist, or Law Officer.
The common thread is that these are all technical roles that need a specific degree, not a general one. Your day-to-day work depends entirely on which post you get. An Assistant Engineer in Water Resources spends time on site inspections and project files. A Drug Inspector does field checks on pharmacies and manufacturing units. A Block Health Statistician works mostly in an office, handling data and reports for the Family Welfare department. Read the post description carefully before you apply for something, because the postings can be spread across the whole state, often in rural or semi-urban areas to start with.
Vacancy details and post breakdown
The 2026 cycle has 508 vacancies (after the latest addendum) spread across 45 posts. Some of the bigger-ticket posts this year:
| Post | Department | Approx. Vacancies |
|---|---|---|
| Block Health Statistician | Family Welfare | 62 |
| Assistant Engineer | Rural Development | 52 |
| Junior Scientific Officer | Forensic Science | 37 |
| Assistant Engineer (Civil) | Water Resources | 34 |
| Drug Inspector | Drugs Control | 9 |
| Various other engineering/science/legal posts | Multiple departments | Remaining spread across 40 posts |
This is not the full list — there are 45 posts in total, several with smaller counts of 1 to 10 vacancies each. Go through the official notification PDF post by post and shortlist only the ones you're actually eligible for, because Paper II (the subject paper) is different for each post group, and you can't switch after applying.
Eligibility
Age limit
Minimum age for most posts is 21 years. Maximum age varies by post, generally between 32 and 42 years for general category candidates, with the usual TNPSC relaxations.
| Category | Age Relaxation |
|---|---|
| SC/SCA/ST | 5 years (no upper limit for several posts) |
| MBC/DNC | 5 years |
| BC/BCM | 3 years |
| Destitute Widows | Up to 10 years |
| Ex-servicemen | As per rules, service period + 3 years |
| PwBD (Differently abled) | 10 years |
Some posts, especially in engineering and forensic science, carry no upper age limit at all for SC/ST candidates. Check the specific post's age column in the notification, don't assume a blanket rule.
Education
This is where CTS is very different from Group 1, 2 or 4. Every post has its own qualification: a B.E./B.Tech in the relevant branch for engineering posts, an M.Sc. in Chemistry, Botany, Zoology, or Environmental Science for scientific posts, an LLB with Tamil proficiency for law/translator roles, and CA/CMA/ICWA for finance-related posts. Read the qualification column for your target post word for word. TNPSC does not accept "equivalent" degrees loosely — if your degree title doesn't match, you can get rejected at document verification even after clearing the exam.
Other requirements
You need to be a domicile-eligible candidate as per TNPSC norms (broadly, you must have studied in Tamil Nadu or meet the residence conditions). Some field posts like Drug Inspector or Geologist may have minor physical fitness requirements mentioned in the specific post notification. There's also a mandatory Tamil eligibility requirement built into Paper I for almost every post.
Application process, fee, and how to apply
You apply online through the TNPSC official portal (tnpscexams.in / tnpsc.gov.in). If you're a first-time applicant, you need to complete One-Time Registration (OTR) first, which costs a nominal fee and stays valid for a few years, so you don't have to redo it for every future TNPSC exam.
| Fee Head | Amount |
|---|---|
| Application/Exam fee (per post/paper) | ₹150 |
| SC/ST/SCA/Destitute Widow/PwBD candidates of Tamil Nadu | Fully exempted |
| Payment mode | Online (net banking, cards, UPI) |
Steps to apply:
- Go to the TNPSC website and log in with your OTR credentials (or create OTR if you're new).
- Select the CTS Non-Interview notification and choose the post(s) you're eligible for.
- Fill in your education, category, and communal certificate details carefully.
- Upload photo and signature as per specifications.
- Pay the fee (unless you're exempt).
- Download and save the confirmation page for your records.
Use the correction window if it opens — don't skip it if you spot an error, because TNPSC is strict about mismatches at verification stage.
Exam pattern
CTS has two written papers.
| Paper | Sections | Questions | Marks | Duration |
|---|---|---|---|---|
| Paper I (Common) | Part A: Tamil Eligibility Test | 100 | 150 | 3 hours |
| Part B: General Studies | 75 | ~150 | (combined with Part A/C) | |
| Part C: Aptitude & Mental Ability | 25 | — | ||
| Paper II (Subject-specific) | Technical/subject paper for your post | 200 | 300 | 3 hours |
Total across both papers works out to roughly 400-plus questions and 450 marks, though the exact split varies slightly by post group. There's negative marking for wrong answers in TNPSC exams generally, so don't guess wildly — a calm, accurate attempt beats a fast, careless one.
Paper I is largely a qualifying-cum-scoring paper depending on the post category, while Paper II usually carries the bigger weight in final merit for technical posts. Don't neglect Paper I though — some posts do count it fully toward the final rank.
Detailed syllabus
Paper I — Part A: Tamil Eligibility Test
Basic Tamil grammar, translation, comprehension passages, and general Tamil language use. This part checks working knowledge of Tamil, not literature-level depth. If you studied in a Tamil-medium school or have basic fluency, this part is very manageable.
Paper I — Part B: General Studies
This overlaps heavily with other TNPSC exams: Tamil Nadu history and culture, Indian polity and constitution, Indian and Tamil Nadu geography, Indian economy, general science, environment and ecology, current events of national and state importance, and Tamil Nadu's development schemes. Use Pareeksha's General Awareness guide to structure this section topic by topic instead of reading randomly.
Paper I — Part C: Aptitude and Mental Ability
Number series, simplification, percentages, ratio and proportion, time and work, time and distance, data interpretation, logical reasoning, puzzles, blood relations, coding-decoding, and basic mental ability questions. This part rewards practice more than raw knowledge. Work through quantitative aptitude and reasoning guides daily rather than cramming formulas the week before.
Paper II — Subject Paper
This is entirely post-specific. If you're applying for Assistant Engineer (Civil), expect core civil engineering subjects: strength of materials, structural analysis, surveying, concrete technology, transportation and highway engineering, environmental engineering, and irrigation. Mechanical engineering posts cover thermodynamics, machine design, manufacturing, and fluid mechanics. Science posts (like Junior Scientific Officer in forensic science) test your specific M.Sc. subject in depth — organic and inorganic chemistry, forensic techniques, toxicology, and lab procedures depending on the specialisation.
There is no single syllabus PDF that covers every post — you have to pull the syllabus annexure specific to your chosen post from the TNPSC notification. Don't study a generic engineering syllabus and hope it matches; each post's subject paper has its own weightage table.
Salary, pay scale, and career growth
Pay depends heavily on the specific post and department, since these sit at different levels in the Tamil Nadu pay matrix. Most Assistant Engineer and equivalent technical posts start around Level 19-20, with basic pay near ₹56,100. Posts like Junior Scientific Officer, Drug Inspector, and Block Health Statistician typically start a bit lower, often in the ₹29,800 to ₹56,900 range depending on the exact post and grade.
On top of basic pay you get Dearness Allowance, House Rent Allowance, and other standard state government allowances. In-hand pay for a fresh Assistant Engineer usually lands between ₹45,000 and ₹65,000 a month depending on posting location.
Career growth in the engineering cadres moves from Assistant Engineer to Assistant Executive Engineer to Executive Engineer over years of service. Scientific and legal posts have their own promotion ladders within their departments. This is a stable, pensionable government career with steady increments, not a fast track to a huge salary, but the security and long-term growth make it worth it for most candidates.
Previous year cut-off
TNPSC has not published a single combined cut-off for CTS because cut-offs are set separately for each of the 45 posts and each category within that post. A post with 60 vacancies and heavy competition will have a very different cut-off from a post with 2 vacancies and a niche qualification requirement. Broadly, engineering posts (Assistant Engineer variants) have historically seen cut-offs in the 55-65% range for general category and lower for reserved categories, while niche science and law posts can vary widely based on how many qualified applicants show up. Once TNPSC publishes the 2026 result, check the official cut-off PDF for your specific post rather than relying on a generic number — it genuinely differs post to post.
Best books and preparation strategy
For Paper I, standard TNPSC Group 1/2 prep material works fine — a good Tamil Nadu history and polity book, a current affairs digest, and an aptitude and reasoning practice book. For Paper II, go straight to your degree-level textbooks. If you're an engineer, your final-year GATE-level notes or the standard textbooks you used in college work better than any generic "CTS guide," because Paper II genuinely tests degree-level knowledge.
A rough month-wise plan if you have about three months:
- Month 1: Cover Paper I fully — Tamil basics, GS topics one by one, and daily aptitude practice. Also start revising your core subject syllabus for Paper II from your degree notes.
- Month 2: Deepen Paper II subject prep with past TNPSC and related state PSC question papers for your subject. Keep Paper I revision going with weekly mock tests.
- Month 3: Full-length mock tests for both papers, timed practice, and focused revision of weak areas. Use Pareeksha's free mock test series and topic-wise practice sets to simulate the real exam feel and track your speed and accuracy.
Don't skip current affairs even for a technical exam — GS in Paper I still asks recent events, and current affairs revision in the last month before the exam pays off directly.
Common mistakes and honest advice
The biggest mistake candidates make is applying for a post without properly matching their degree title to the eligibility criteria, then getting stuck at document verification after clearing the exam. Read the qualification line for your exact post twice before applying.
The second mistake is treating Paper II lightly because it "should be easy since I studied this in college." Four years of engineering doesn't automatically translate to exam-ready recall. You need targeted revision, not just familiarity.
Third, don't ignore Paper I because it doesn't matter as much. For many posts it contributes fully to your final rank, and a weak Paper I score can pull down a strong Paper II performance. Finally, don't wait for the result to start preparing for certificate verification. Keep your degree and community certificates ready and correctly matched to your application well in advance.
FAQ
Is TNPSC CTS Non-Interview really without an interview? Yes, this exam category is fully non-interview. Selection is based on written exam performance and certificate verification only.
Can I apply for more than one post in the same CTS notification? Yes, if you meet the eligibility for multiple posts, you can apply for more than one, but each application needs a separate fee payment (unless exempted) and you'll write a separate Paper II for each subject group.
What is the exact vacancy count for 2026? It started at 461, rose to 476, and the latest addendum takes it to 508. Always check the latest addendum on tnpsc.gov.in since this number has moved a few times this cycle.
Is there negative marking in TNPSC CTS? Yes, TNPSC exams generally carry negative marking for wrong answers, so avoid random guessing.
Do I need to know Tamil to apply? Paper I includes a mandatory Tamil Eligibility Test. Basic working knowledge of Tamil is expected for almost all posts.
What is the age limit for CTS posts? Minimum 21 years for most posts. Maximum varies by post, generally 32-42 years for general category, with standard relaxations for reserved categories.
Which post has the highest vacancy this year? Block Health Statistician (Family Welfare) leads with around 62 vacancies in the 2026 cycle, followed by Assistant Engineer (Rural Development).
How is the salary structured? Pay depends on the specific post's pay level in the TN pay matrix, roughly ranging from ₹29,800 to over ₹56,000 basic pay depending on the post, plus DA, HRA and other allowances.
When will the 2026 exam be held? The written exam is scheduled to start around 16 August 2026, spread over multiple dates depending on the post group. This is tentative until your hall ticket confirms your exact date.
Where can I find the official syllabus for my specific post? Download the official CTS Non-Interview notification PDF from tnpsc.gov.in and check the post-specific syllabus annexure for your subject paper.

Final word
CTS is a good option if you have a technical degree and want a stable Tamil Nadu government job without going through an interview panel. The exam itself isn't easy — Paper II demands real subject knowledge, not last-minute cramming — but it rewards focused, degree-level preparation more than generic exam tricks. Pick your post carefully, match your qualification exactly, and build a study plan around your specific Paper II subject rather than treating this like a general aptitude test. Start early, use Pareeksha's study plan tool to structure your weeks, and check the official tnpsc.gov.in site regularly for updates on your exact exam date and any last-minute notices. Good luck.
