SSC CGL DEST Evaluation Rules & Criteria

Strict Omission Rule: Any words, sentences, or lines left untyped due to the timeout are treated as omissions and counted strictly as Full Mistakes.
SSC CGL DEST evaluation criteria
Error Tolerance DEST The maximum allowed error percentage to qualify is strictly 20% for UR category, 25% for OBC/EWS, and 30% for SC/ST categories.

Expert Pro Tip

Finish the complete passage within the 15-minute window first, then focus on reducing avoidable typing errors during repeated practice sessions.

SSC CGL DEST Typing Test: Everything You Need to Know in 2026

The SSC CGL Data Entry Speed Test (DEST) is a qualifying skill test conducted during Tier-II for posts such as Tax Assistant. Unlike the written papers, DEST carries no marks toward your merit list — yet failing it disqualifies you entirely. Candidates must type a passage containing roughly 2000 key depressions within 15 minutes, which translates to a sustained speed of approximately 8000 key depressions per hour under exam conditions.

How SSC CGL Calculates Typing Errors

SSC classifies every deviation from the source passage as either a Full Mistake or a Half Mistake. Full mistakes include word omissions, wrong substitutions, extra additions, and incomplete words at timeout. Half mistakes cover spacing errors, capitalization issues, punctuation mistakes, word transpositions, and incorrect paragraph formatting (such as using spaces instead of the Tab key). Your total error percentage is computed from both categories combined, and this percentage — not raw speed alone — determines whether you qualify.

Category-Wise Error Ceilings for DEST

The permissible error thresholds are generous compared to CHSL but still unforgiving if ignored. Unreserved (UR) candidates must stay at or below 20% errors. OBC and EWS candidates have a 25% ceiling, while SC/ST candidates may reach 30%. Completing all 2000 key depressions but exceeding your category limit still results in failure, which is why accuracy-focused practice matters as much as raw typing speed.

Omission Penalties and Time Strategy

The strict omission rule means unfinished content at the buzzer counts as full mistakes. Many candidates type the first two-thirds of a passage quickly, then slow down and leave the final section blank — a fatal strategy. Build endurance for the full 15-minute window. Practice finishing the entire passage first, then refine accuracy across multiple sessions rather than chasing speed in isolation.
