Selection Architecture: 100-Question Written Examination and Work Experience Weightage
The final merit list for BTSC Fisheries Extension Officers will be calculated using a composite evaluation model incorporating a competitive written test and prior departmental service experience. The written screening exam consists of 100 multiple-choice questions carrying 100 marks to be completed within a two-hour duration, scaled down to a total written component weight of 75 marks. The test features a strict negative marking penalty, deducting one-quarter mark (0.25 marks) for each incorrect answer, requiring accuracy from test takers. The remaining 25 marks will be evaluated based on verified professional work experience in relevant government and allied aquaculture projects, providing candidates with structured criteria to secure their appointment within Bihar's expanding fisheries and rural development sector.
