The Bihar Public Service Commission (BPSC) conducts the recruitment exam for Assistant Education Development Officer (AEDO) — a key post responsible for planning, monitoring, and implementing education programs at the district level in Bihar. With 935 vacancies announced under this recruitment cycle, the BPSC AEDO exam has drawn strong competition. This guide covers the complete BPSC AEDO syllabus, exam pattern, marking scheme, and section-wise topics to help you prepare strategically.
The BPSC AEDO Exam 2026, conducted from 14th to 21st April 2026, has been cancelled due to reported attempts of malpractice during the examination. The BPSC will announce the revised examination date soon.
BPSC AEDO Exam Pattern: Quick Overview
The BPSC AEDO selection process has two stages: a Written Examination followed by Document Verification. There is no interview stage.
The written exam consists of 3 objective-type papers, all held offline in MCQ format:

Key points:
- Negative marking: 1/3rd mark is deducted for every incorrect answer across all three papers.
- Paper 1 (General Language) is qualifying only — candidates must score a minimum of 30% separately in both English and Hindi sections, but these marks are not added to the final merit.
- Paper 2 (General Studies) and Paper 3 (General Aptitude) marks are counted toward the final merit list.
- Paper 1 is further split into General English (30 marks) and General Hindi (70 marks).

BPSC AEDO Preparation Tips
- Don't skip General Language prep just because it's qualifying — a 30% threshold in both English and Hindi separately means weakness in either language section alone can disqualify you, regardless of your General Studies or Aptitude score.
- Balance Bihar-specific and national-level GS preparation — History, Geography, Polity, and the Freedom Struggle sections all carry a strong Bihar-focused component alongside national coverage.
- Practice aptitude daily — with 100 marks riding on General Aptitude, regular practice of numerical and reasoning problems is essential, since this paper often decides the final cutoff.
- Stay current with news — both national and international current affairs are tested, so following a daily news digest alongside monthly compilations helps.
- Solve previous years' papers — this helps you gauge the difficulty level and question pattern specific to BPSC AEDO, which can differ from other BPSC exams.
- Manage your 6-hour exam day — with three separate 2-hour papers, build stamina through full-length mock tests rather than only practicing sectional tests.
