The SSC CHSL (Combined Higher Secondary Level) examination mandates a qualifying Skill Test / Typing Test as part of Tier-II. The test differs depending on whether you applied for Lower Division Clerk (LDC) / Junior Secretariat Assistant (JSA) or Data Entry Operator (DEO).
1. Post-Wise Speed Requirements & Test Duration
| Post Applied | Medium | Duration | Key Depressions (KDPH) | Net Speed Required |
|---|---|---|---|---|
| LDC / JSA | English | 10 Minutes | 10,500 KDPH | 35 WPM |
| LDC / JSA | Hindi | 10 Minutes | 9,000 KDPH | 30 WPM |
| DEO (General) | English | 15 Minutes | 8,000 KDPH | 27 WPM |
| DEO Grade ‘A’ (CAG/Ministries) | English | 15 Minutes | 15,000 KDPH | 50 WPM |
2. Category-Wise Permissible Error Percentage
| Category | Permissible Error Limit (LDC/JSA) | Permissible Error Limit (DEO) |
|---|---|---|
| UR (General) | 7% | 5% |
| OBC / EWS | 10% | 7% |
| SC / ST | 10% | 7% |
| Ex-Servicemen (ESM) | 10% | 7% |
| PwD | 10% | 7% |
3. How Words and Key Depressions are Calculated
In SSC examinations, 1 standard word = 5 key depressions (keystrokes), including spaces and punctuation marks.
$$\text{Words Typed} = \frac{\text{Total Key Depressions Typed}}{5}$$
$$\text{Gross Speed (WPM)} = \frac{\text{Words Typed}}{\text{Duration in Minutes}}$$
$$\text{Net Speed (WPM)} = \frac{\text{Words Typed} - (\text{Mistakes} \times \text{Penalty})}{\text{Duration in Minutes}}$$
4. Key Takeaways for Aspirants
- Hindi Font: SSC CHSL Hindi typing uses Mangal font (with Remington Gail or Inscript layout).
- 10-Minute Endurance: Unlike 1-minute speed tests, maintaining high velocity over 10 continuous minutes without pausing is critical.
