BTSC Dairy Technology Officer Selection Process 2026

The selection for BTSC Dairy Technology Officer 2026 is merit-driven and structured in a way that balances written examination performance with relevant field experience. The final merit list is prepared out of 100 marks, but candidates must first qualify the written stage before experience marks are added.

The recruitment process moves in the following sequence:

• Computer Based Test (CBT)
• Addition of verified work experience marks
• Preparation of category-wise merit list
• Document Verification

The Computer Based Test acts as the screening foundation. Only those candidates who secure the minimum qualifying percentage in CBT are considered eligible for merit preparation.

Work experience marks (maximum 25) are awarded strictly as per the rules defined in the notification and are added after CBT score normalization (if the exam is held in multiple shifts). The final selection depends entirely on combined merit, not interview performance. This makes CBT performance decisive, while experience acts as a ranking advantage.

BTSC Dairy Technology Officer Exam Pattern 2026

The BTSC Dairy Technology Officer examination will be conducted in Computer Based Mode and will consist exclusively of objective-type questions from Dairy Technology and Dairy Chemistry domains.

The CBT carries 75 marks and plays the most critical role in shortlisting candidates. The questions are technical and subject-oriented, designed to assess conceptual clarity, applied processing knowledge, and analytical understanding.

Qualifying Requirements:

To be considered for merit preparation, candidates must secure the prescribed minimum qualifying percentage in the CBT:

• General – 40%
• BC – 36.5%
• EBC – 34%
• SC/ST/Women/Divyang – 32%

There is no descriptive paper, no interview stage, and no separate section-wise cutoff mentioned. Performance in the single CBT determines eligibility for final ranking. Due to negative marking, calculated attempts and accuracy-based solving strategy become essential.
