About the SSC CHSL typing test
The SSC CHSL Skill Test is the qualifying Tier-II stage for LDC and JSA posts. It is conducted on computers using the TCS iON interface: a passage appears in the upper pane, you type in the lower pane, and the timer counts down in the header. The software does not highlight words or show your live speed, so candidates who practise only on colourful practice sites are often surprised on exam day. This simulator reproduces that plain interface and evaluates your answer with the SSC method of full and half mistakes.

- Eligible PwD candidates using a scribe get compensatory time (15 minutes in total).
- Backspace works, but spelling check, auto-correct and copy-paste are not available.
Always check the latest notification. Recruiting bodies revise speed, duration and error rules from time to time. Information here was last reviewed on 18 October 2026. Official website: ssc.gov.in. You can change the required speed and error limit in the simulator’s Advanced options.
How the SSC CHSL typing test is evaluated
SSC-style evaluation: key depressions, full and half mistakes
Speed is measured in key depressions: every letter, space and punctuation mark you press counts. 35 words per minute is equivalent to 10,500 key depressions per hour because one “word” is taken as 5 key depressions.
Your typed matter is compared word by word with the passage. Omitting a word, typing a wrong or misspelt word, or adding a word that is not in the passage is a full mistake.
Spacing errors (two words joined or one word split), wrong capitalisation and punctuation mistakes are half mistakes.
Error percentage = (full mistakes + half mistakes ÷ 2) ÷ words in the passage you attempted × 100. You qualify if your speed meets the requirement and your error percentage is within the limit for your category.
Worked example: To reach 10,500 key depressions per hour in 10 minutes you must type about 1,750 key depressions – roughly 307 average English words including spaces.

Preparation tips for SSC CHSL
- Do not stop to re-read: the passage pane does not mark your position, so keep your eyes on the source text and trust your fingers.
- Every spelling mistake is a full mistake – a slow correct word is cheaper than a fast wrong one.
- Capitalisation and punctuation errors are half mistakes, so do not ignore commas and full stops.
- Practise with the live-speed display hidden (as in the real test) for at least two weeks before the exam.

About this exam interface
This simulator copies the TCS iON computer-based test layout used by SSC, RRB and many central recruiters: a header with the exam name, candidate details and a countdown timer, the passage in an upper pane, and a plain typing box below it. There is no word highlighting and no live speed meter – exactly like the real test.

SSC CHSL typing test – FAQs
How many words do I need to type in the SSC CHSL typing test?
For English you need about 350 correct words in 10 minutes (35 wpm). For Hindi you need about 300 words (30 wpm). SSC actually counts key depressions – 10,500 per hour for English – so longer words also help.
Is backspace allowed in the SSC CHSL typing test?
Yes, backspace and the arrow keys work in the TCS iON typing window, but there is no spell-check. Corrections cost time, so aim for accuracy in the first attempt.
What is a half mistake in the SSC typing test?
Errors of spacing, capitalisation and punctuation are usually treated as half mistakes, while omission, substitution, addition of words and spelling errors are full mistakes.
Is this SSC CHSL typing test free?
Yes. TypingPrep is completely free. There is no registration – your results and your own paragraphs are stored only in your browser.
