📊 Major Post Distribution & Vacancy Details

Out of the 839 total vacancies, a substantial portion is heavily concentrated in infrastructure, survey, and training roles. If your background aligns with Civil, Mechanical, or Electrical engineering disciplines, the sheer volume of vacancies plays drastically in your favor.

High-Volume Openings:

Road Inspector (Rural Development and Panchayat Raj Dept.): 149 vacancies

Overseer / Junior Draughting Officer (Rural Development and Panchayat Raj Dept.): 129 vacancies

Junior Training Officer (JTO - Various Trades) (Employment and Training Dept.): 119 vacancies

Assistant Agricultural Officer (Agriculture Department): 110 vacancies

Junior Draughting Officer (Water Resources Wing - PWD): 101 vacancies

Junior Draughting Officer (Highways Department): 46 vacancies

The remaining slots are distributed among niche roles like Motor Vehicle Inspector (Grade-II), Sub-Inspector of Fisheries, and Textile Inspectors.

🎯 Eligibility Criteria & Requirements

To clear the baseline screening, candidates must ensure they meet the criteria as specified by the commission:

1. Educational Qualifications

The requirements are highly post-specific, catering strictly to professional technical certifications:

ITI/NTC/NAC Holders: Eligible for specific Junior Training Officer trades, specific technician scales, and specialized field units.

Diploma Holders: Required for key positions like Road Inspector, Junior Draughting Officer (JDO), and Overseer (typically requiring a Diploma in Civil Engineering or equivalent).

Language Requirement: You must possess strong operational knowledge of Tamil. Candidates who didn't take Tamil as a core subject in SSLC or HSC will need to clear the mandatory Tamil Eligibility Test within the examination framework.

2. Age Limits (As of July 1, 2026)

Minimum Age: 18 Years for most entry-level technical roles (21 years for certain posts like Motor Vehicle Inspector).

Maximum Age: While the absolute cap for unreserved categories hovers around 32-34 years depending on the post, candidates belonging to SC, ST, MBC, BC, and BCM categories generally enjoy extensive age relaxations according to prevailing state government rules.

📝 No Interview! Understanding the Selection Process

The defining advantage of the CTSE (Diploma/ITI level) recruitment drive is that it features no interview stage. Your selection rests entirely on a merit-based, single-tier written framework followed by verification:

(OMR / CBT Format)            (Document Check)              (Based on Marks & Merit)

The Exam Structure:

The exam typically splits into two distinct modules:

Paper I (Subject Paper): Standard multiple-choice questions curated to the relevant ITI or Diploma engineering syllabus of your respective field.

Paper II (General Studies): Divided into two parts—a qualifying Tamil Language Eligibility Test (SSLC Standard) and a general section focusing on General Studies, Aptitude, and Mental Ability.

Because there are no behavioral or oral test rounds, every single mark scored in your technical and aptitude papers acts as a direct multiplier for your final ranking.
