The general process is as follows:
Visit the official SAC recruitment portal.
Open the online response/objection link.
Log in using the required credentials.

Clearly mention the reason for challenging the answer.

SAC has specified that queries or objections relating to questions or answer keys must be submitted through the designated online response link. Objections sent through other communication channels are not entertained.
Candidates should not wait until the last day to submit an objection. The objection facility is available only for the period specified by SAC. Once the objection window closes, candidates may not be able to challenge the provisional answer key.
The final answer key is prepared after the submitted objections are examined by subject experts.
The ISRO SAC Technician B Response Sheet 2026 helps candidates see the answers they actually marked during the computer-based examination.
Candidates should compare their recorded responses with the provisional answer key rather than relying only on memory of the questions.
The response sheet can help candidates:
Check every marked answer.
Identify correct and incorrect responses.
Calculate their estimated score.
Identify questions that may require an objection.
Keep a record of their performance before the result.
This makes the response sheet particularly important when candidates are close to the expected qualifying marks.
Candidates must use the official marking scheme while calculating their estimated marks.
According to the SAC recruitment notification, the Technician B written test consists of 80 multiple-choice questions. Each correct answer carries 1 mark, while 0.33 mark is deducted for every incorrect answer. The test duration is 90 minutes.
Therefore, candidates can use the following formula:
Estimated Score = Number of Correct Answers − (Number of Incorrect Answers × 0.33)
For example, if a candidate answers 60 questions correctly and gets 10 questions wrong:
Estimated Score = 60 − (10 × 0.33) = 56.70 marks
Candidates should calculate their score using the official response sheet and answer key rather than an unofficial answer key.
The Technician B written examination consists of 80 objective questions for 80 marks and has a duration of 90 minutes.
The syllabus is curriculum-based and is designed to test both the theoretical and practical knowledge of candidates.

Candidates should note that the Technician B syllabus is designed to assess the breadth and depth of the prescribed technical curriculum, including theoretical and practical understanding.
Candidates must meet the prescribed qualifying criteria in the written examination.
As per the recruitment notification:
Unreserved candidates: 32 out of 80 marks
Reserved candidates: 24 out of 80 marks, where the post is reserved
These are the minimum qualifying marks specified for the written test.
However, simply meeting the qualifying marks does not automatically guarantee selection. Candidates are shortlisted for the next stage based on their performance in the written examination.
After the provisional answer key objection process is completed, SAC will examine the valid objections through subject experts.
The final answer key is then prepared after considering the objections. Candidates should therefore avoid treating the provisional answer key as the final authority.
The subsequent selection process includes the Technician B skill test. According to the official recruitment notification, candidates are shortlisted for the skill test based on their written-test performance in a 1:5 ratio, with a minimum of 10 candidates.
The skill test is an important stage of the Technician B recruitment process.
The official notification states that the skill test is conducted on a go/no-go basis, meaning it is qualifying in nature. The marks obtained in the skill test are not considered for final selection.
The qualifying criteria are:
| ISRO SAC Technician B Skill Test | |
| Category | Skill Test Qualifying Marks |
| Unreserved | 50/100 |
| Reserved, where applicable | 40/100 |
The detailed pattern of the skill test is communicated to candidates shortlisted for this stage.
The ISRO SAC Technician B selection process consists of:
Written Test → Shortlisting → Skill Test → Final Selection
The written examination is used to shortlist candidates for the skill test. The skill test is qualifying in nature and its marks are not added to the selection score.
In case of a tie in written-test marks, SAC has specified tie-breaking provisions. A candidate with a valid NAC score receives preference over a candidate without an NAC score. If a tie still exists under the applicable conditions, marks obtained in Class 10/SSC/SSLC/Matriculation are used as the second tie-breaker.
Candidates should keep track of all important answer-key and recruitment updates.
