SSC CHSL JSA/LDC Hindi Typing Test

The SSC CHSL Hindi Typing Test is the Tier-2 Skill Test for JSA (Junior Secretariat Assistant) and LDC (Lower Division Clerk) posts under the Staff Selection Commission Combined Higher Secondary Level examination — for candidates who selected Hindi as their typing language at the time of application. Like its English counterpart, it is a pass-or-fail qualifier: zero merit marks, but failing it eliminates you from the selection no matter how strong your Tier-1 and Tier-2 written scores are.

Hindi candidates must achieve a net speed of 30 WPM — equivalent to 9,000 key depressions per hour (KDPH) — within a 10-minute session. Error deductions must not exceed 7% of gross words typed for unreserved (UR) and EWS candidates, or 10% for OBC, SC, ST, and PwBD candidates. On paper, 30 WPM looks easier than the 35 WPM required for English. In practice, Hindi typing is significantly harder for most candidates — the Inscript keyboard layout is not intuitive for non-native learners, matras add a layer of precision English candidates never face, and a single wrong matra counts as a full mistake deducting one complete word.

SSC CHSL accepts two Hindi keyboard layouts: Mangal Inscript (Unicode) and Kruti Dev 010 (Remington Gail layout). Your layout is fixed at application time and confirmed on your admit card. This is the most critical detail on this entire page — practising on Mangal Inscript when your admit card says Kruti Dev, or vice versa, means you will sit in the exam hall with a keyboard you have never properly trained on. That is the single most avoidable reason candidates fail.

This page covers the full Hindi-specific preparation picture: 30 WPM net speed formula, the Full Mistake and Half Mistake system (including how wrong matras are categorised), which keyboard layout to choose and why, common matra and conjunct errors that trip up Hindi candidates specifically, and a practice strategy calibrated to the 10-minute exam format. If you opted for English typing at application, see the SSC CHSL English Typing Test page — the layout, error types, and target speed are entirely different.

You need 30 WPM net speed — calculated after subtracting all full and half mistake deductions from your gross words typed, then dividing by 10 minutes. Gross WPM does not matter; only net WPM determines pass or fail. 30 WPM equals 9,000 key depressions per hour (KDPH), the official unit in SSC notifications. The Hindi passage is approximately 1,500–1,550 characters. Hindi conjuncts (matras and half-characters) require more keystrokes per word than English, which is why the Hindi target is 30 WPM while English is 35 WPM — the key-depression count at 9,000 KDPH reflects that higher keystroke-per-character ratio.

The SSC CHSL Hindi typing interface is a TCS iON-based terminal with no spell-check, no live error highlights, and no auto-correct. Unlike English QWERTY which is familiar to most candidates, Hindi typing introduces an additional challenge: the keyboard layout itself is unfamiliar unless you have specifically drilled it. Conjuncts, matras, and half-characters each require specific key combinations that must become muscle memory before the exam. No amount of general typing practice transfers to Hindi — only layout-specific daily drilling does.

SSC CHSL Hindi errors split into Full Mistakes (one word deducted) and Half Mistakes (0.5 word deducted). At 30 WPM over 10 minutes your gross word count is roughly 300 words. Seven percent of 300 is 21 deduction units — fewer than 2.2 errors per minute for the UR limit. Hindi typing introduces additional error sources that English typists never face: wrong matra (vowel diacritic), missing half-character in a conjunct, and wrong Unicode character that looks visually similar but is evaluated as a full mistake. These silent errors are invisible to the eye but caught by the evaluator's character-level comparison.

SSC CHSL gives reserved category candidates (OBC, SC, ST, PwBD, ESM) a wider error margin — 10% versus 7% for unreserved candidates. This is an explicit differentiation in SSC CHSL notifications, unlike some other exams that apply a uniform limit. PwBD candidates eligible for a scribe receive 15 minutes instead of 10. Always verify your category-specific error limit in the official SSC CHSL notification for your specific recruitment year, as exact percentages can change between cycles.

SSC CHSL accepts two Hindi keyboard layouts — Mangal Inscript and Kruti Dev 010 (Remington Gail). Your exam centre and admit card will specify which one applies to you. These are not interchangeable: Inscript and Remington place characters on completely different physical keys. Practising on Kruti Dev and arriving to find your centre uses Mangal Inscript — or vice versa — is a race you cannot win. Confirm your layout from the admit card before starting any serious practice, then drill exclusively on that layout.
