TN TRB Assistant Professor Syllabus – WildLife Biology
Introduction
The TN TRB Assistant Professor Wildlife Biology Syllabus is designed to evaluate a candidate’s understanding of animal ecology, conservation principles, and biodiversity management. Conducted by the Tamil Nadu Teachers Recruitment Board (TRB), this exam aims to recruit qualified professionals to teach Wildlife Biology and related life science subjects in Government Colleges. The syllabus includes major areas such as wildlife ecology, habitat management, conservation strategies, and environmental legislation — ensuring aspirants have both theoretical and practical knowledge essential for teaching and research roles.
