TNPSC Combined Technical Services Exam Pattern
The TNPSC Combined Technical Services exam pattern depends on whether you are applying for Non-Interview, Diploma and ITI, or Interview Posts. The 2026 notifications use a Paper I with Tamil Eligibility, General Studies and Aptitude and Mental Ability, then a Paper II linked to the post. The Interview stream adds an interview score.
The details that can affect your preparation include Paper II duration, mode and subject standard. A code for an engineering paper can have a different format from a translation or reporter paper. Use the notice and its addendum to verify your specific scheme before setting practice timers or predicting your ranking marks.

TNPSC CTS exam pattern by 2026 stream
Stream | Written structure | Later stages |
|---|---|---|
Non-Interview 04/2026 | Paper I code 503 and post-specific Paper II. The dashboard includes CBT, objective OMR and descriptive formats. | Follow certificate verification and counselling notices where applicable |
Diploma and ITI 06/2026 | Paper I code 501 and Paper II matched to diploma or trade | Follow the notice's certificate verification and counselling instructions |
Interview 08/2026 | Paper I code 503 and Paper II for the post | Interview, plus certificate verification and counselling where applicable |
The Non-Interview addendum includes a 150-minute Translation paper, code 462, alongside three-hour subject sessions. The Diploma and ITI dashboard provides the notice, hall ticket and links to subject papers. A timer based on another code can give a misleading picture of your pace.
Paper I and ranking in the Interview stream
Component | Questions | Marks | Ranking treatment |
|---|---|---|---|
Paper I Part A, Tamil Eligibility | 100 | 150 | Qualifying. The stated floor is 60 marks. |
Paper I Parts B and C, General Studies and Aptitude | 75 and 25 respectively | 150 combined | Counted after the applicable Tamil eligibility requirement |
Paper II | Post-specific | 300 | Counted after the applicable Tamil eligibility requirement |
Interview | Separate assessment | 60 | Added for final ranking |
Final ranking scale | Paper I Parts B and C plus Paper II and interview | 510 | Subject to the notice's selection and reservation rules |
Paper I has a three-hour duration in the 08/2026 Interview notice. For Tamil and English Reporter posts, Paper II is a 100-question diploma-standard subject paper lasting 90 minutes. Check Section 6 for your own post's format and the treatment of applicable exemptions.
Build practice around the actual paper mode
Check the clock. Record the duration of each paper or practical format before creating a practice schedule.
Separate the marks. For the Interview example, a candidate who meets the Tamil condition and earns 110 in Parts B and C, 210 in Paper II and 42 in the interview has 362 ranking marks out of 510.
Use the official response rules. Check how your mode handles blanks, answer changes or response choices. Follow the notification and hall ticket rather than importing a scoring rule from a mock.
Reserve review time. In a technical paper, recheck units and option numbers. In a descriptive paper, recheck whether each answer addresses the task.
Keep selection and preparation in view
Use the TNPSC CTS syllabus guide to map each part before starting timed sets. Review the cut-off guide to distinguish a Tamil requirement from a written minimum and a closing score. On Testkart, check the question style and subject code before choosing practice. Track qualifying and ranking marks separately in Testkart or any other practice record.
