SSC CHSL (Combined Higher Secondary Level) examination includes a qualifying typing test for posts such as Lower Division Clerk (LDC) and Junior Secretariat Assistant (JSA). This guide explains the official process, speed requirements, evaluation method, and preparation strategy based on standard SSC CHSL Typing rules and exam practice.
1. Why SSC CHSL Includes a Typing Test
Clerical and administrative posts under SSC CHSL require regular drafting, file maintenance, and data entry work. To ensure minimum operational efficiency, the Staff Selection Commission conducts a qualifying typing test as part of the Tier-II process for LDC/JSA posts.
The typing test is qualifying in nature. This means candidates must meet the prescribed speed and accuracy standards. Even if you score high in the written examination, failure in the typing test results in disqualification.
2. Exam-Wise Requirements
The following table summarizes the typing and skill test requirements under SSC CHSL. Always verify details from the latest official notification before preparation.
| Exam / Recruitment | Language | Font / Layout | Required Speed | Duration |
|---|---|---|---|---|
| SSC CHSL (LDC / JSA Typing Test) | English or Hindi | QWERTY / Inscript / Kruti Dev (as notified) | 35 WPM (English) / 30 WPM (Hindi) | 10 min |
| SSC CHSL (DEO Skill Test) | English | QWERTY | 8,000 KPH (≈ 26–27 WPM) | 15 min |
Important: The LDC/JSA test is measured in Words Per Minute (WPM), while the DEO post is evaluated in Key Depressions Per Hour (KPH). Criteria may vary slightly depending on department allocation.
3. How Typing Speed Is Calculated
Understanding the official evaluation formula helps you prepare strategically and avoid common misconceptions.
Words Per Minute (WPM) Method
For LDC/JSA posts, typing speed is calculated using the standard SSC formula:
- 1 word = 5 characters (including spaces and punctuation)
- Gross WPM = (Total characters typed ÷ 5) ÷ Time in minutes
- Net WPM = Gross WPM − Total errors
Example: If a candidate types 1,750 characters in 10 minutes:
- Gross WPM = (1750 ÷ 5) ÷ 10 = 35 WPM
- If 4 full errors occur → Net WPM = 35 − 4 = 31 WPM
Keystrokes Per Hour (KPH) Method
For Data Entry Operator (DEO) posts, performance is measured in key depressions per hour:
- KPH = (Total keystrokes typed ÷ Time in minutes) × 60
- SSC DEO requirement: 8,000 KPH (approximately 26–27 WPM)
- Some departments may require higher standards such as 15,000 KPH
Error Treatment
- Full Error: Incorrect, missing, or extra word — usually deducted as 1 error.
- Half Error: Minor spacing or punctuation mistake — may count as 0.5 error depending on evaluation software.
- Accuracy Impact: Excessive errors reduce net WPM and may result in failing the qualifying threshold.
4. Language, Fonts, and Keyboard Layouts
English Typing
English typing is conducted using the standard QWERTY keyboard layout. The passage is displayed on-screen, and candidates must replicate it accurately within 10 minutes.
Hindi Typing — Inscript (Unicode)
Hindi typing in many SSC examinations uses Unicode fonts such as Mangal with the Inscript keyboard layout:
- Unicode-based — text is stored as actual Hindi characters.
- Vowels and consonants are logically arranged across the keyboard.
- No external font installation is required on most modern systems.
Hindi Typing — Kruti Dev (Legacy)
In certain cases, legacy fonts such as Kruti Dev may be used:
- Non-Unicode graphical Hindi font.
- Typically uses the Remington keyboard layout.
- Requires font installation for offline practice.
Candidates must confirm the exact font and layout mentioned in the official SSC notification before starting preparation.
5. Preparation Strategy for SSC CHSL Typing Test
A structured preparation plan ensures both speed development and accuracy control.
- Target-Based Practice: Aim for at least 5 WPM above the qualifying requirement (e.g., practice at 40 WPM if target is 35 WPM).
- Strict Time Simulation: Practice in exact 10-minute sessions to build stamina.
- Error Monitoring: Maintain a log of recurring spelling or spacing mistakes.
- Layout Mastery: Practice exclusively on the layout you will use in the exam (QWERTY, Inscript, or Remington).
- Consistency: Daily 20–30 minute sessions are more effective than irregular long sessions.
No Registration Required: Most online typing platforms allow immediate exam-style practice. Select your language, choose the correct layout, start the timer, and evaluate your WPM and accuracy after each attempt.
