Numerical Reasoning Tests

• What are numerical reasoning tests?

  A numerical reasoning test is a timed psychometric test that measures how quickly and accurately you work with numerical information. Questions present data in tables, charts and graphs, and ask you to apply percentages, ratios, averages and currency conversions to reach the right answer.

  Numerical reasoning is one of the most widely used psychometric tests in recruitment. Employers across finance, consulting, technology, retail, the armed forces and the public sector use it, usually early in the process for graduate schemes, apprenticeships and professional roles.

  The maths itself rarely goes beyond what you covered at school. What makes the test challenging is the time limit, the multi-step questions and answer options built around the most common mistakes. That is also why practice works: candidates who already know the question formats spend their time calculating, not decoding.

• Why do employers use numerical reasoning tests?

  Most jobs involve numbers somewhere: budgets, targets, margins, forecasts or performance data. A numerical reasoning test gives employers an objective, standardised measure of how comfortably you handle that side of a role, in a way that is directly comparable across every applicant.

  Scores also carry information a CV cannot. Two candidates with identical qualifications can perform very differently under time pressure, and research on selection methods consistently places ability tests among the strongest predictors of job performance. For high-volume graduate intakes the test does a practical job too: it narrows a large field to a shortlist before interviews begin.

  The test is rarely the whole decision. Most employers combine your score with interviews, and often with other assessments such as verbal reasoning or a situational judgement test, to build a rounded picture.

• What is the numerical reasoning test format?

  Most numerical reasoning tests give you 15 to 30 multiple-choice questions, with somewhere between 45 and 90 seconds per question. Each question usually starts from a table, chart or short scenario; you extract the relevant figures, perform one or two calculations and pick the right option.

  The exact format depends on the test publisher. SHL, Korn Ferry, Saville and Aon all use recognisably different question styles, timings and interfaces, and some run adaptive tests where the questions get harder as you answer correctly. Your invitation email normally names the publisher, and once you know it, it is worth practising that specific style.

  Calculators are usually permitted for online tests, and rough paper is essential. Read the instructions before you start: they confirm the number of questions, the time limit and whether wrong answers are penalised.

• What skills does numerical reasoning test?

  The core skills are percentages, ratios, fractions, averages, currency conversion and reading values accurately from tables and graphs. Questions frequently combine two of these in a single problem, for example extracting the right figures from a chart and then calculating a percentage change.

  Just as important is the discipline around the maths: choosing the right figures from data that contains more than you need, keeping track of units and scale (thousands versus millions catches many candidates), and pacing yourself so one difficult question does not swallow three questions' worth of time.

  If your basics are rusty, target them directly. Percentage change, ratio splitting and reading charts cover a large share of real questions, and ten minutes of focused arithmetic a day sharpens speed noticeably within a couple of weeks.

• How are numerical reasoning tests scored?

  Your raw score, the number of correct answers, is converted into a percentile by comparing it against a norm group: other people who have taken the same test, such as previous graduate applicants. Scoring in the 70th percentile means you did better than 70 per cent of that group, not that you got 70 per cent of the questions right.

  Employers typically set a percentile cut-off for progressing, and it varies by employer and role, so the same performance can pass at one company and fall short at another. Most tests score only correct answers, but a few penalise guessing, and adaptive tests weight harder questions more heavily, so check the instructions before deciding how to pace yourself.

  Because most candidates cluster around the middle of the distribution, even a modest improvement from practice moves you a long way up the percentile ranking. That is the strongest argument for taking several timed practice tests before the real one.
