Definitive Guide to the Railway Recruitment Board NTPC Typing Skill Test
The Railway Recruitment Board Non-Technical Popular Categories examination includes a critical Typing Skill Test, commonly termed TST, for candidates who have qualified the Computer Based Tests for clerical appointments. Posts requiring the TST include Senior Clerk cum Typist, Junior Accounts Assistant cum Typist, Accounts Clerk cum Typist, and Junior Clerk cum Typist across all railway zones. The test is strictly qualifying in nature; marks secured in the typing test are not factored into the final merit ranking, yet failure to qualify the typing test results in absolute exclusion from consideration for these lucrative posts.
Prescribed Speed Benchmarks and Operational Conditions
Candidates appearing for the RRB NTPC Typing Skill Test are required to fulfill the following explicit speed standards during a continuous testing window:
- English Medium Candidates: A minimum net typing speed of thirty words per minute, equivalent to typing three hundred words accurately within ten minutes.
- Hindi Medium Candidates: A minimum net typing speed of twenty-five words per minute, equivalent to typing two hundred and fifty words accurately within ten minutes, using KrutiDev or Mangal font layouts.
The Distinctive Railway 5% Mistake Exemption and Penalty Calculus
The scoring methodology implemented by the Railway Recruitment Board differs markedly from other central government examinations. Aspirants must thoroughly understand the mathematical mechanics of the five percent exemption rule and the subsequent ten-word mistake penalty:
The 5% Mistake Allowance
The examination authority allows candidates an error tolerance of five percent of the total words typed. Mistakes committed within this five percent threshold carry no negative penalty. For example, if a candidate types four hundred words in ten minutes, five percent of four hundred equals twenty mistakes. Up to twenty mistakes are forgiven without lowering the net word count.
The 10-Word Penalty for Excess Mistakes
Any mistake committed beyond the permissible five percent quota incurs a severe penalty: for every single additional mistake, ten words are deducted from the total words typed. This penalty can rapidly reduce an otherwise rapid typist's net score below the passing line.
Official Railway Net Speed Formula
| Evaluation Parameter | Mathematical Representation | Concrete Calculation Example |
|---|---|---|
| Total Words Typed | W | Candidate types 360 words in 10 minutes. |
| Total Mistakes Committed | M | Candidate makes 24 mistakes during the test. |
| Allowable Exempt Mistakes (5%) | E = W * 0.05 | 360 * 0.05 = 18 mistakes allowed without penalty. |
| Excess Penalized Mistakes | X = M - E | 24 - 18 = 6 excess mistakes. |
| Words Deducted as Penalty | P = X * 10 | 6 excess mistakes * 10 = 60 words deducted. |
| Net Words Qualified | N = W - P | 360 - 60 = 300 net words. |
| Net Speed (Words Per Minute) | Speed = N / 10 Minutes | 300 / 10 = 30.0 WPM (Exactly Qualified for English). |
Essential Preparation Guidelines for RRB Aspirants
Due to the penal nature of the ten-word deduction rule, careless typing at high speeds is fatal in the RRB TST. Practicing across Typingram's 45 lessons trains candidates to type with sustained rhythmic accuracy, ensuring that error totals remain well within the 5% exempt quota.
