TNPSC CTSE Diploma/ITI 2026: 839 technical posts and tonight's application checklist

If you are considering the Tamil Nadu Public Service Commission's Combined Technical Services Examination (Diploma / ITI Level), the most important fact is the application cutoff: the official Notification No. 06/2026 gives 15 August 2026 at 11:59 PM as the last date and time for submitting the online application. The notification covers 839 vacancies across 56 post listings, from technical and inspection roles to Junior Training Officer trades. That breadth is useful, but it also creates the main risk: a Diploma or ITI holder must match the exact post code and subject paper instead of treating the recruitment as one generic qualification route. This guide brings the deadline, correction window, qualification checks, exam scheme, fee and submission evidence together. The official notification and live TNPSC application page remain the controlling sources.

The official vacancy table totals 839 posts, but the entries sit across different departments, pay levels and technical routes. Examples include 129 Overseer / Junior Draughting Officer vacancies in Rural Development and Panchayat Raj, 101 Junior Draughting Officer vacancies in Water Resources–Public Works, 110 Assistant Agricultural Officer vacancies, 149 Road Inspector vacancies, and multiple Junior Training Officer trades. The table also carries reservation and vacancy notes, including backlog or shortfall markings and a note that some selected candidates may be posted anywhere in India. Vacancy totals are described as tentative and can be modified before the physical certificate-verification or counselling stage, so use the post code and the official table rather than relying on a headline total alone.

The notification's qualification matrix is the part to read before choosing a subject paper. It covers Diploma, ITI, National Trade Certificate, National Apprenticeship Certificate, undergraduate and postgraduate routes, but the required subject changes by post. For example, Motor Vehicle Inspector asks for a relevant Automobile or Mechanical diploma plus a valid licence; Mines Foreman has a specialised certificate-of-competency condition; Road Inspector points to Civil Draughtsmanship; and the Junior Training Officer entries map individual trades such as Fitter, Electrician, Welder, Wireman, Plumber and Drone Pilot to their own subject paper and post code. The notice also says that the prescribed qualification must have been obtained in the required order of study and, where experience is prescribed, the experience must follow the qualification. Use the PDF's post-specific row as the answer to your case, not a shortened social-media summary.

The written examination has a common Paper I and a technical Paper II. Paper I runs for three hours in OMR mode: Part A is the Tamil Eligibility Test with 100 questions for 150 marks at SSLC standard; Part B has 75 General Studies questions for 150 marks; and Part C has 25 Aptitude and Mental Ability questions for 150 marks. Paper II is the selected Diploma or ITI subject paper, with 200 questions for 300 marks in CBT mode and a three-hour duration. The ranking total uses Part B and Part C of Paper I together with Paper II, for 450 marks. The notification says Paper I and Paper II are compulsory, and Paper II plus Parts B and C are evaluated only after the prescribed minimum is secured in Tamil.

The notification sets the examination fee at ₹100 when submitting the online application, unless a valid exemption is claimed. Each additional subject paper selected in the application adds ₹100. The fee must be paid online through the prescribed route; offline instruments are not accepted. If an online payment fails, check the transaction status before trying again and do not use the browser's Back or Refresh controls while the payment response is pending. A successful transaction should lead to an application number or applicant ID. Keep that evidence with the final application preview or printout.

The application can be edited up to the last date. After the first deadline, TNPSC has provided a three-day Application Correction Window from 19 August 2026 at 12:01 AM to 21 August 2026 at 11:59 PM. The notice says candidates can edit details during that period, but no modification is allowed after the window closes. Choose only subject papers for which you hold the prescribed qualification; a claim added after submission is not a safe recovery plan. AvsarIQ's live record is verified from multiple official sources, while its branch-matrix review remains pending for manual normalization, so the primary PDF should be used for the final row-level decision.

The official TNPSC notification PDF contains the complete post table, qualification matrix, age rules, exam scheme, fee instructions, annexures and syllabus. The live TNPSC application page is the current route to the notification and application controls. AvsarIQ adds a live opportunity snapshot and a profile comparison layer, but it is not the recruiting authority and does not make a final eligibility decision. Check the official page again immediately before submitting in case TNPSC posts a new notice or changes the application flow.
