Applications for the Bihar School Librarian Eligibility Test (LET) 2026 open today, 1 October — the gateway to roughly 5,800 school librarian posts across Bihar. You have a tight 21-day window. Here’s exactly how to apply, who’s eligible, the exam pattern, and the mistakes that get applications rejected.
What this exam actually is
LET stands for Library Eligibility Test — officially the Vidyalaya Pustakalayadhyaksh Patrata Pariksha. It’s conducted by the Bihar School Examination Board (BSEB) and is the qualifying step for school librarian recruitment in the state’s schools. Clearing it makes you eligible to be considered for the librarian posts being filled — it is not a final-selection exam on its own.
Who can apply
- Qualification: a Bachelor’s degree in Library Science (B.Lib.Sc) from a recognised university, with at least 45% marks (5% relaxation for reserved and special categories).
- Residency: Indian citizen, domiciled in Bihar.
Age limit (as on 1 August 2026)
| Category | Maximum age |
|---|---|
| Unreserved — Male | 37 years |
| Unreserved — Female | 40 years |
| BC / EBC | 40 years |
| SC / ST | 42 years |
| Divyang (all categories) | +10 years relaxation |
