Under Advertisement No. 28/2026, the selection of Fishery Extension Officers is primarily based on an objective Computer Based Test (CBT) followed by experience weightage:

The 100 questions in the CBT will test the candidate's core domain proficiency across essential disciplines of Fisheries Science:

Under Advt. 28/2026, negative marking is enforced in the CBT examination to ensure strict accuracy standards:

The official notification specifies that candidates must obtain the minimum qualifying marks of 30% in the written examination to be considered for merit compilation:

If the Computer Based Test is conducted in multiple shifts, BTSC will implement an Equi-Percentile / Standard Normalization methodology to balance difficulty disparities across question papers:

• Normalization ensures that candidates appearing in a comparatively tougher shift are evaluated equitably against those in an easier shift.
• Raw marks scored by the candidate in each shift will be converted into a normalized score before calculating the 75% CBT weightage.
• The normalized score is computed using the percentile-distribution method approved by BTSC and the Department of Personnel and Administrative Reforms.
• In single-shift examinations, the raw score itself constitutes the final CBT score without requiring normalization.

The syllabus for the Fishery Extension Officer CBT is aligned with the ICAR Post Graduate syllabus for Fisheries Science disciplines:

Detailed sub-topic distribution for comprehensive preparation:

Under Advt. No. 28/2026, the selection process comprises three well-defined stages:

The total selection evaluation is conducted on a 100-mark composite scale as detailed in Advertisement 28/2026:

Guidelines for resolving equal composite scores between multiple candidates during final merit compilation:

1. Higher CBT Marks: The candidate with higher marks in the Computer Based Test (CBT) will be placed higher in the merit order.
2. Higher Age: If CBT marks are also equal, the candidate older in age (earlier Date of Birth) will be ranked higher.
3. Alphabetical Order: If DOB is identical, the alphabetical order of candidate names as per English Devanagari/matriculation certificate will resolve the tie.

Shortlisted candidates based on composite merit will be called for document verification at the Commission's headquarters:

• Candidates must present all original documents along with 2 self-attested sets of photocopies.
• Failure to attend DV on the assigned date and time will result in forfeiture of candidature.
