SSC CHSL posts 2026: LDC, JSA and DEO explained, pay level, typing and skill test
SSC CHSL 2026 fills three kinds of Group C post in central government offices: Lower Division Clerk / Junior Secretariat Assistant (LDC/JSA) at Pay Level-2, Data Entry Operator (DEO) at Pay Level-4 and Level-5, and Data Entry Operator Grade 'A' at Pay Level-4. Everyone sits the same Tier-I and the same Tier-II papers; what differs is the qualifying test at the end. LDC/JSA candidates take a Typing Test (35 words a minute in English or 30 in Hindi), while DEO candidates take a Skill Test of data-entry speed. For DEO posts in three named offices, Class 12 must be in Science with Mathematics. Which post you finally get depends on your Tier-II merit and the post preferences you submit. This article sets out each of these from the notice; for exam dates and how to apply, see our SSC CHSL 2026 guide.
The posts and their pay levels
Paragraph 1 of the SSC CHSL 2026 notice lists the posts:
| Post | Pay level | Notice paragraph |
|---|---|---|
| Lower Division Clerk (LDC) / Junior Secretariat Assistant (JSA) | Level-2 | 1.1 |
| Data Entry Operator (DEO) | Level-4 and Level-5 | 1.2 |
| Data Entry Operator, Grade 'A' | Level-4 | 1.3 |
The notice gives the pay range of each level; we do not repeat the rupee figures here, as the take-home amount depends on allowances that change over time and differ by place of posting. Read paragraph 1 of the notice for the ranges.
The posts are in ministries, departments and offices of the Government of India and in various constitutional bodies, statutory bodies and tribunals. All carry All India Service Liability, so you can be posted anywhere in India (paragraph 17.18), and appointment begins with two years of probation (paragraph 17.17).
What the posts involve
The notice does not describe daily duties, so the following is a broad picture rather than a rule:
- LDC/JSA is the entry-level clerical post in a government office: keeping files and records, receiving and sending letters and papers, typing notes and letters, and supporting the officers of a section. "LDC" and "JSA" are names used in different offices for this same level of post.
- DEO and DEO Grade 'A' work mainly on computers, entering and checking data in the office's systems. The speed demanded in the Skill Test reflects that.
Which test each post needs
All candidates who qualify in Tier-I take all four sections of Tier-II (paragraph 17.4). Sections I and II make the merit; Section III (Computer Knowledge) and Section IV (Skill Test or Typing Test) are qualifying only (paragraphs 17.6 and 17.9). Section IV is held in Session-II on the same day as the written sections (paragraph 13.9.13.1).
| Post | Section IV test | What it asks (paragraph 13.9.13) | Time |
|---|---|---|---|
| DEO / DEO Grade 'A' in the offices named in para 8.1 | Skill Test, Part A | 15,000 key depressions per hour: an English passage of about 3,700–4,000 key depressions | 15 minutes |
| DEO / DEO Grade 'A' in all other offices | Skill Test, Part B | 8,000 key depressions per hour: an English passage of about 2,000–2,200 key depressions | 15 minutes |
| LDC/JSA | Typing Test, Part C | 35 words per minute in English or 30 in Hindi, on a given passage | 10 minutes |
Points from the notice worth knowing:
- The Skill Test is compulsory for DEO posts; no candidate is exempted (13.9.13.6).
- The Typing Test medium (English or Hindi) is chosen in the application form and cannot be changed later (13.9.13.7 ii). 35 and 30 words a minute correspond to about 10,500 and 9,000 key depressions an hour.
- Hindi typing must be done in the Mangal font only; another font means not qualifying (13.9.13.7 viii).
- Candidates eligible for a scribe get 5 extra minutes in the Skill and Typing Tests.
- Some candidates with disabilities who are certified as unable to type can be exempted from the Typing Test (13.9.13.7 vii); the exemption does not apply to the DEO Skill Test.
Typing speed is accuracy at speed: the passage is judged on correct entry. Our SSC CHSL typing test article explains how to practise for it, and a few minutes a day from now is enough to make a real difference by Tier-II.
The Science-with-Mathematics condition for some DEO posts
Paragraph 8.1 sets a stricter qualification for DEO and DEO Grade 'A' posts in three offices:
- the Ministry of Consumer Affairs, Food and Public Distribution,
- the Staff Selection Commission,
- the Ministry of Culture.
For these, you need Class 12 passed in the Science stream with Mathematics as a subject. For every other post (LDC/JSA, and DEO in all other offices), Class 12 or equivalent in any stream is enough (paragraph 8.2). The qualification had to be held by 7 October 2026 (paragraph 8.3).
These are also the offices whose DEO posts carry the faster Part A Skill Test. And the notice allows separate category-wise cut-offs for three groups: DEO posts in the para 8.1 offices, DEO posts elsewhere, and LDC/JSA (paragraph 17.3).
If you studied Arts or Commerce, or Science without Mathematics, do not list the para 8.1 DEO posts in your preferences. If you are allotted a post whose educational, physical or medical standard you do not meet, the notice says your candidature is rejected and you are not moved to another preference (paragraph 17.11).
How post preferences work
Paragraphs 15 and 17.7 to 17.11 of the notice set out the rules:
- When: SSC takes post and department preferences through an Online Option Form on its website before the result (the first round of tentative allocation, FRTA). Watch ssc.gov.in after Tier-II for the window.
- Only what you list counts: you are not considered for a post or department you do not list, however high your merit.
- Miss the window, miss the allocation: candidates who do not submit preferences in time are not considered for any post in the FRTA, and get no second chance (15.3, 17.8).
- Final means final: preferences cannot be changed once submitted.
- How allocation works: in each category, candidates are taken in order of Tier-II merit, and each gets their highest preference that still has a vacancy. Once you are given your first available preference, you are not considered for any other (17.10).
- Standards are checked after allocation: for example, LDC posts in the Border Roads Organisation have physical and medical standards set out in Annexure-XVI (15.4). If you list such a post and cannot meet its standards, you lose the allotment.
Worked example of the allocation rule
Suppose a candidate lists, in order: DEO in a para 8.1 office, then LDC in a ministry, then JSA in another office. If her merit reaches the DEO post, she gets it and is not considered for the other two. If she studied Commerce, that allotment would later be rejected on the education condition, and she would not fall back to LDC. Listing only posts you are eligible for avoids this.
Practical advice when the form opens:
- List every post you would genuinely accept, in your real order of preference. Leaving out posts only reduces your chances.
- Put the post you most want first, even if you think your marks may not reach it; a higher preference you miss does no harm.
- Remove posts with standards you cannot meet (Science with Maths, physical standards).
- Remember that a DEO post needs the Skill Test and an LDC/JSA post the Typing Test, both qualifying (17.6). If you list both kinds, prepare for both.

Is the typing test compulsory for DEO in SSC CHSL?

Can a Commerce or Arts student become a DEO through SSC CHSL?
Yes, except in the Ministry of Consumer Affairs, Food and Public Distribution, the Staff Selection Commission and the Ministry of Culture, where DEO posts need Class 12 in Science with Mathematics.
What is the difference between LDC and JSA?
They are the same level of post (Pay Level-2) under different names in different offices, with the same exam, the same Typing Test and the same qualification.
Can I change my post preference after submitting it?
No. The notice says preferences are final and irreversible once submitted, and you are not considered for any post you did not list.
Is the typing test speed 35 wpm for SSC CHSL?
Yes, for LDC/JSA in English: 35 words a minute. In Hindi it is 30 words a minute, typed in the Mangal font, in a 10-minute test.
