ISRO Stenography Test Syllabus & Pattern 2026 (Annexure-V)
Applicable only to JPA and Stenographer posts.
Test Structure
- Shorthand test: 300 words @ 60 words per minute (Time: 5 minutes)
- Transcription: Passage transcribed on computer (Time: 30 minutes, with compensation time as applicable to PwBD candidates)
- Shorthand method: Must strictly follow Pittman’s Shorthand — longhand is not permitted, and failure to comply means the transcript will not be evaluated.
Stenography Test – Passing Criteria
| Category | Maximum Mistakes Allowed |
|---|---|
| UR | 10% mistakes |
| Reserved Categories (against notified reserved vacancies) | 12% mistakes |
Criteria for Evaluation of Stenography Transcripts
Full Mistakes (counted as complete errors):
- Every omission of a word or figure (for a group of omitted words, count as many mistakes as the actual number of words omitted)
- Every substitution of a word or figure (mistakes equal the number of words/figures replaced; a figure written correctly in either numerals or words is acceptable and not counted as an error)
- Every addition of a word, figure, or group not occurring in the dictated passage
Half Mistakes (counted as 0.5 errors):
- Wrong spelling, including transposition or omission of letters (ignored for proper nouns and unfamiliar names; repeated misspelling of the same word counts only once)
- Using singular/plural noun incorrectly
- Use of a small letter at the beginning of a sentence
Important Notes on Stenography Evaluation
- More than one error in a single word: All errors are counted, but total mistakes in a single word cannot exceed one full mistake.
- Alternate spellings/forms: Each passage comes with a list of words that can be spelt/written in more than one accepted form (e.g., “Honourable” as Hon’ble, Hon., honourable, hon. — all treated as correct).
- No penalty beyond listed errors: Candidates are not penalised for any error type other than those specifically described above.
