Eligibility Criteria

Educational Qualification

Only candidates possessing a University degree and who are non-recommended candidates of Civil Services Examination 2024 (CSE-2024), as listed on the UPSC Pratibha Setu Portal, are eligible to apply for CSIR ASO Recruitment 2026. This is a closed eligibility route — candidates who don’t meet this specific condition should not apply, as applications from others will not be considered under this recruitment drive.

Nationality

The applicant must be a citizen of India.

Application Fee

Payment is accepted online only, through SBI Collect.

Selection Process

CSIR Recruitment 2026 does not involve a fresh written exam in the conventional sense. Instead, the process works like this:

1. Shortlisting — Candidates are shortlisted for the Computer Proficiency Test (CPT) in a ratio of 1:5 per category (five times the vacancies, subject to a minimum of five), based on their total marks (Mains + Personality Test) in UPSC’s CSE-2024.
2. Computer Proficiency Test (CPT) — A qualifying-only test of 100 marks and 1 hour duration, assessing Word Processing, Spreadsheet, and Slide Presentation skills. Category-wise minimum threshold marks: UR 40%, EWS/OBC 37%, SC/ST 35%, all PwBD categories 30%.
3. Final Selection — Based entirely on total marks obtained in UPSC’s CSE-2024 (Mains + Personality Test), subject to qualifying the CPT threshold. The CPT itself does not add marks to the final merit — it is purely a qualifying hurdle.

The CPT will tentatively be held in Delhi, though CSIR reserves the right to conduct it elsewhere if required. A single merit list will be prepared, and cadre allocation (General, Finance & Accounts, or Stores & Purchase) will be decided by CSIR based on merit and the candidate’s stated preference — once allotted, the cadre cannot be changed.

Documents Required

• Proof of date of birth (PDF, under 1 MB)
• Educational qualification certificates from 10th onwards, including passing certificate and mark sheet (merged PDF, under 1 MB)
• CSE-2024 mark sheets — both Preliminary and Mains + Personality Test (single merged PDF, under 1 MB)

Who Should Apply

CSIR ASO Recruitment 2026 is specifically designed for candidates who appeared in UPSC’s CSE-2024 Mains and Personality Test but were not recommended for a service — it is not open to the general public or fresh graduates outside this group. If you fall into this exact category and are listed on the UPSC Pratibha Setu Portal, this CSIR ASO Recruitment 2026 is a genuinely rare second opportunity to secure a Group B government post without writing another full competitive exam.

How to Increase Your Chances of Selection

Since final merit is based on your existing CSE-2024 marks, all candidates applying for CSIR ASO Recruitment 2026 should focus primarily on qualifying the CPT.

• Since final merit is based on your existing CSE-2024 Mains and Personality Test marks, your main task now is simply to qualify the CPT — don’t overlook basic MS Office proficiency (Word, Excel, PowerPoint) assuming it will be easy without practice.
• Practice typing and formatting a passage, building a simple spreadsheet, and creating a short PowerPoint presentation under a strict one-hour time limit, since that mirrors the actual CPT format.
• Decide your cadre preference (General, Finance & Accounts, or Stores & Purchase) thoughtfully before submitting, since the allotted cadre is final and cannot be changed later.
• If you’re currently working in a Government Department, start the No Objection Certificate (NOC) process early — this is often the most time-consuming part of document verification, not the certificates you already have.

Common Mistakes to Avoid While Applying

• Applying without actually confirming your name appears on the UPSC Pratibha Setu Portal list of non-recommended CSE-2024 candidates — this is a strict, non-negotiable eligibility condition.
• Locking your profile page in a hurry without verifying every entry, since profile details cannot be modified once locked.
• Uploading photographs or signatures that don’t meet the exact pixel and file-size specifications, which can lead to application issues later.
• Waiting until the last date to apply, risking last-minute website load issues — CSIR has explicitly stated it holds no responsibility for failed submissions due to heavy last-day traffic.
• Assuming NOC or resignation-related documents can substitute for the actual No Objection Certificate — CSIR has clarified they cannot.
