WBPSC IDO Syllabus 2026 Revised: Industrial Development Officer Exam Pattern, Topics & Strategy

The Public Service Commission, West Bengal (WBPSC) has released the detailed advertisement for the recruitment of Industrial Development Officer (IDO) under the Directorate of Micro, Small & Medium Enterprises, Government of West Bengal. The notification (in continuation of Indicative Advertisement No. 15/2024) announces 247 vacancies in Pay Level 10 and, most importantly, prescribes a revised, section-wise scheme of examination – a 100-mark written test divided into seven subjects, followed by a 15-mark interview. Online applications are open from 6 November to 26 November 2026.

Many websites still show an older two-part pattern for the IDO exam (General Studies and Mental Ability only, with no negative marking). The official advertisement now clearly lists seven subjects with fixed marks, negative marking of 0.25 and an interview of 15 marks. This guide explains the revised WBPSC IDO syllabus 2026 and exam pattern exactly as given in the notification, along with expected topics for each section, a preparation strategy, a 30-day study plan, FAQs and links to our free study notes for every subject.

What Is Revised in the WBPSC IDO Exam Pattern 2026?

The detailed advertisement gives a clear subject-wise distribution of marks. The table below compares the older pattern still shown on many websites with the revised scheme prescribed in the official notification.

WBPSC IDO Exam Pattern 2026 (Revised)

The written examination (Part-I) carries 100 questions of 1 mark each, to be answered in 1 hour 30 minutes. Answers are marked on an OMR sheet and evaluated electronically.

The "suggested time" column is our recommendation for time management, not part of the official notification.

Selection Process

Figure 2: Selection process for WBPSC Industrial Development Officer 2026

• The Commission may fix category-wise cut-off marks in the written examination to call candidates for the interview.
• There are no qualifying marks in the interview.
• The Final Merit List is prepared on the aggregate of Part-I and Part-II out of 115 marks.
• If two or more candidates have equal aggregate marks, the older candidate (by date of birth) gets preference.
• Candidates with poor performance in the Bengali knowledge test (held at the interview) are liable to have their candidature cancelled (except candidates whose mother tongue is Nepali).

Category-wise Qualifying Marks (in the Aggregate)

The Commission may further relax qualifying marks if a sizable number of reserved posts remain unfilled. Qualifying marks are only the minimum – actual selection depends on merit and the number of vacancies.

How Negative Marking Works – Example

Each correct answer gives +1 and each wrong answer costs −0.25; unattempted questions get zero. Suppose a candidate attempts 80 questions and gets 64 right and 16 wrong:
Score = 64 × 1 − 16 × 0.25 = 64 − 4 = 60 marks.
Four wrong answers cancel one correct answer. So answer only when you can eliminate at least two options with confidence.
