Exam GuidesUpdated 22 Jul 20268 min read

SSC CGL is best known for its tough computer-based tiers, but candidates who opt for Tax Assistant posts in CBIC (Central Board of Indirect Taxes and Customs) and CBDT (Central Board of Direct Taxes) face one more stage: the Data Entry Speed Test, or DEST. It is a short, qualifying skill test, yet every cycle some candidates lose a well-earned post because they underestimated it.

This guide explains how the SSC CGL DEST works as per recent notifications, how it is evaluated, and how to prepare efficiently. Always confirm the final rules with the latest official SSC CGL notification, because details can change between cycles.

Which SSC CGL Posts Need the DEST?

The DEST applies to Tax Assistant posts:

  • Tax Assistant in CBIC
  • Tax Assistant in CBDT

Other SSC CGL posts have their own requirements (for example, some posts have a computer proficiency test instead), but for Tax Assistant the DEST is the skill test that matters. Your post preferences decide whether you will be called for it, so fill them carefully.

Understanding 8,000 Key Depressions per Hour

Key depressions per hour (KDPH) means the number of keys you press in one hour. Every letter, space, punctuation mark and Shift-assisted capital counts as a key depression in the calculation.

Since the test lasts 15 minutes, which is one quarter of an hour:

  • 8,000 KDPH / 4 = 2,000 key depressions in 15 minutes
  • 2,000 / 15 = about 133 key depressions per minute
  • In WPM terms (1 word = 5 keystrokes): 133 / 5 = about 27 WPM

So the DEST speed requirement is modest compared to the SSC CHSL typing test (35 WPM English). The challenge is doing it accurately for a full 15 minutes on an unfamiliar keyboard under exam pressure. For the formulas behind these numbers, see our explainer on WPM and KDPH.

Aim for at least 2,400-2,600 correct keystrokes in 15 minutes during practice. That gives you a buffer of 20-30% above the requirement, which is exactly what you need on exam day.

How Is the DEST Evaluated?

The typed matter is compared against the given passage. The method of counting mistakes and the maximum permissible errors are laid down in the official notification. In practice, what matters for you is:

  • The number of correct key depressions you type in 15 minutes
  • The number and type of errors in your typed text

Unchecked mistakes such as skipped words, extra words and wrong spellings pull your effective speed down. Since exact thresholds come from the notification, the smartest approach is simple: type cleanly and comfortably above the speed requirement.

Test Interface and Rules

The DEST is typed on a computer in a special test interface. Based on how SSC skill tests generally run:

  • The passage is displayed on screen along with a typing area.
  • A countdown timer shows the remaining time.
  • Copy-paste, spell-check and auto-correct are not available.
  • Candidates must follow the instructions given at the centre regarding editing keys.

Because instructions can differ slightly by cycle and venue, read the on-screen instructions carefully before the timer begins.

Is the DEST in Hindi or English?

As per recent notifications, the DEST passage is in English. Unlike the SSC CHSL LDC/JSA typing test, there is no Hindi option for the DEST. If you have been practising only Hindi typing, shift your focus to English early.

How Much Preparation Do You Need?

It depends on your starting point. Take a 15-minute style exam test and check your correct keystrokes:

Correct keystrokes in 15 min Status Suggested daily practice
Below 1,500 Not ready 45-60 min, including touch typing basics
1,500-2,000 Borderline 30-45 min, focus on accuracy and stamina
2,000-2,400 Likely pass 20-30 min, maintain and simulate exam conditions
Above 2,400 Safe 15-20 min, keep practising until the test

A 4-Week DEST Preparation Plan

Week 1: Foundations

  • Check your posture and finger placement. If you look at the keyboard, start learning touch typing.
  • Do short 5-minute passages focusing on accuracy above 95%.

Week 2: Numbers and punctuation

  • DEST-style passages often contain numbers, commas, full stops and capital letters. Practise the top number row with correct fingers.
  • Drill weak keys identified in Week 1.

Week 3: Stamina

  • Move to full 15-minute tests at least four days a week.
  • Watch your speed in the last five minutes. If it drops sharply, you need more stamina work.

Week 4: Exam simulation

  • One full 15-minute DEST mock every day.
  • Practise at the same time of day as your scheduled test.
  • If possible, practise on a desktop keyboard similar to what exam centres use.

Tips From the Typing Room

  • Do not chase the passage length. You do not need to finish the passage. You need enough correct key depressions.
  • Capital letters count. Use the Shift key on the opposite hand for clean, fast capitals.
  • Do not stop for small errors. Unless the instructions encourage corrections, a steady rhythm usually gives better results than frequent backspacing.
  • Keep your eyes on the passage. Looking down at the keyboard is the biggest time-waster.
  • Stay calm in the first minute. Nervous typists make most of their errors in the first 60 seconds.

For structured practice, the English typing course takes you from home row drills to full passages, and the SSC CHSL DEO DEST test uses the same 8,000 KDPH standard if you want more mock passages.
