What is SSC CHSL?
The SSC CHSL (Staff Selection Commission – Combined Higher Secondary Level) is a highly popular, national-level competitive exam conducted annually in India by the Staff Selection Commission (SSC). It serves as the primary gateway for candidates who have completed their Higher Secondary Education (10+2 / Class 12) to secure prestigious, stable, and secure Group “C” non-technical positions across various central government ministries, administrative departments, and offices.
Securing a position through SSC CHSL allows young aspirants to enter the central government workspace early, handling clerical tasks, data processing, and foundational administrative workflows without requiring a university graduation degree.

- Merit Formulation: Tier-1 marks are strictly qualifying. The final rank compilation and government department allocation are decided solely on the basis of marks secured in Tier-2.
SSC CHSL Comprehensive Eligibility Criteria
To apply for the SSC CHSL examination, candidates must satisfy three core parameters: Nationality/Citizenship, Age Limit, and Minimum Educational Qualifications.
1. Nationality / Citizenship
A candidate must be either:
- A citizen of India, or

2. Age Limit & Category Relaxations
The general age bracket for SSC CHSL positions is 18 to 27 years. The exact date calculation depends on the official cut-off date stated in the year’s recruitment notification.
Category-Wise Upper Age Relaxation

3. Minimum Educational Qualification
The foundational requirement is a 10+2 (Class 12) Pass certificate. However, the specific academic stream guidelines vary across the posts as follows:
| Name of the Post | Essential Educational Qualification | Stream / Requirements |

Note: Candidates who are appearing in their 12th standard or equivalent examination can also apply provisionally, provided they successfully pass and acquire the educational qualification on or before the crucial cut-off date specified in the official notification.
SSC CHSL Updated Exam Pattern
The Staff Selection Commission (SSC) conducts the Combined Higher Secondary Level (CHSL) examination in two online stages: Tier-1 and Tier-2. Both stages are entirely Computer-Based Tests (CBT).
Tier-1: Preliminary Examination (Qualifying Stage)
The Tier-1 exam acts purely as a screening test. The marks secured in this tier are not counted for the final merit list, but clearing the aggregate cut-off is mandatory to qualify for Tier-2.
- Total Questions: 100
- Total Marks: 200
- Total Time: 60 Minutes (No sectional timings; time can be distributed across sections freely)
- Question Type: Objective Multiple-Choice Questions (MCQs)
- Negative Marking: 0.50 marks deducted for every incorrect answer.
Tier-1 Exam Structure
| Section / Subject | Number of Questions | Maximum Marks | Total Time Allotted |
|---|---|---|---|
| Part I: English Language (Basic Knowledge) | 25 | 50 | 60 Minutes (80 Minutes for scribe-eligible candidates) |
| Part II: General Intelligence (Reasoning) | 25 | 50 | |
| Part III: Quantitative Aptitude (Basic Arithmetic Skills) | 25 | 50 | |
| Part IV: General Awareness | 25 | 50 | |
| Total | 100 | 200 | 60 Minutes (1 Hour) |
Tier-2: Main Examination (Merit-Deciding Stage)
Final selection and department allocation depend entirely on Tier-2 performance. Tier-2 is conducted in two sessions on the same day. Session-I includes objective and computer awareness modules, while Session-II covers typing/skill tests.
- Total Marks: 360 Marks
- Negative Marking: 1 Mark deducted for every incorrect MCQ in Section-I, Section-II, and Section-III (Module-I).
Session-I (Duration: 2 Hours 15 Minutes)
| Section | Module | Subject | No. of Questions | Marks Per Question | Maximum Marks | Sectional Time | Nature of Module |
|---|---|---|---|---|---|---|---|
| Section-I | Module-I | Mathematical Abilities | 30 | 3 Marks | 90 | 60 Minutes (Total for Section-I) | Merit-Scoring |
| Module-II | Reasoning & General Intelligence | 30 | 3 Marks | 90 | |||
| Section-II | Module-I | English Language & Comprehension | 40 | 3 Marks | 120 | 60 Minutes (Total for Section-II) | Merit-Scoring |
| Module-II | General Awareness | 20 | 3 Marks | 60 | |||
