Numerical Reasoning in SHL Tests

SHL numerical reasoning tests are among the most widely used pre-employment assessments in the world. Companies across finance, consulting, technology, consumer goods, and the public sector rely on these tests to evaluate how well candidates interpret data, perform calculations, and draw conclusions from numerical information under time pressure. If you have applied for a graduate scheme at a Big Four accounting firm, a management consulting position, or a corporate role at a Fortune 500 company, there is a strong chance that an SHL numerical reasoning test is part of your hiring process.

This guide covers everything you need to know about the SHL numerical reasoning test: its format, the types of questions you will encounter, how scoring works, common mistakes to avoid, and a detailed preparation strategy that will help you perform at your best. The information here is based on the current SHL Verify and SHL Interactive test formats used by employers worldwide.

SHL Numerical Test Format and Structure

SHL offers several versions of its numerical reasoning test, but the most common formats used by employers today are the SHL Verify Numerical Ability test and the SHL Interactive Numerical test. Both assess the same core skills, but they differ slightly in structure and delivery.

The SHL Verify Numerical Ability test is the version most candidates encounter. It typically contains 18 to 25 multiple-choice questions with a total time limit of 17 to 35 minutes, depending on the version selected by the employer. Each question presents a data set, usually a table, chart, bar graph, or pie chart, followed by a question that requires you to extract and manipulate the data to arrive at the correct answer. You select your answer from four or five options.

The SHL Interactive Numerical test is a newer format that uses drag-and-drop interactions and other interactive question types instead of traditional multiple-choice. The underlying skills being assessed are the same, but the way you input your answer differs. This format is becoming more common among employers who want a more engaging candidate experience.

Both versions share several important characteristics. Each question is independent, meaning you do not need to carry information from one question to the next. The data set changes with every question or every small block of questions. Time pressure is significant, with most candidates reporting that they feel rushed during the test. An on-screen calculator is provided in most versions, though you should confirm this before your test day.

Major employers that use SHL numerical reasoning tests include Deloitte, PwC, KPMG, EY, Barclays, HSBC, Unilever, Procter and Gamble, Citigroup, and many others. SHL's parent company, now part of the broader talent assessment market, reports that millions of candidates complete SHL assessments each year across more than 150 countries.

Common Question Types on SHL Numerical Tests

SHL numerical reasoning questions are designed to mirror the kind of data analysis you would perform in a professional role. The questions are not about advanced mathematics. They test your ability to read data accurately, identify the right operation, execute the calculation, and select the correct answer from a set of closely spaced options.

Here are the question types you are most likely to encounter:

Percentage calculations are the single most common question type on SHL numerical tests. You may be asked to calculate percentage increases or decreases between time periods, find what percentage one value represents of another, or determine the effect of a percentage change on a base figure. For example, a table might show quarterly revenue for three product lines, and the question asks you to calculate the percentage change in total revenue between Q1 and Q3.

Ratios and proportions require you to compare values across categories or time periods. A typical question might present a stacked bar chart showing the distribution of employees across departments and ask you to express the ratio of engineering staff to sales staff, or to determine how many additional hires in one department would bring the ratio to a specified target.

Data interpretation from charts and graphs tests your ability to read values accurately from visual representations. You might need to read a specific data point from a line graph, compare values across multiple series in a grouped bar chart, or identify the segment with the largest share in a pie chart. The challenge here is precision, as answer options are often very close together, and a misread axis or scale can lead you to the wrong choice.

Currency and unit conversions appear in tests designed for roles with an international focus. You may need to convert figures from one currency to another using a provided exchange rate, or convert between units such as thousands and millions. These questions test attention to detail as much as calculation ability.

Revenue, profit, and cost calculations mirror business-style analysis. You might receive a table showing cost of goods sold, operating expenses, and revenue for several divisions, and be asked to calculate gross profit margin, identify the most profitable division, or determine total operating costs as a percentage of revenue.

Weighted averages and combined data questions require you to combine information from multiple rows or columns in a data set. For example, you might need to calculate the average selling price across three stores, weighted by the number of units sold at each store.

Question Type	What It Tests	Example Scenario	Frequency
Percentage change	Growth and decline calculations	Revenue change between quarters	Very common
Ratios and proportions	Comparing relative values	Staff ratios across departments	Common
Data interpretation	Reading charts and graphs accurately	Extract values from a bar chart	Very common
Currency/unit conversion	Precision with different scales	Convert sales figures to a common currency	Moderate
Revenue and profit	Business-style calculations	Gross margin from a P&L table	Common
Weighted averages	Combining data from multiple sources	Average price weighted by volume	Moderate

How SHL Numerical Tests Are Scored

Understanding how SHL scores your test helps you set realistic expectations and focus your preparation on what actually matters.

SHL uses norm-referenced scoring for its numerical reasoning tests. This means your raw score, the number of questions you answered correctly, is not the primary metric. Instead, your performance is compared to a norm group, a large sample of previous test-takers who completed the same or a similar version of the test. Your result is reported as a percentile rank. If you score in the 70th percentile, it means you performed better than 70 percent of the people in the norm group.

Employers set their own minimum percentile thresholds for each role. A graduate programme at a top-tier consulting firm might require the 80th percentile or higher, while a general management role at a mid-sized company might accept the 50th percentile. Your recruiter may or may not tell you the threshold in advance.

Some SHL tests also produce a sten score, which places your performance on a standardized scale from 1 to 10. Sten scores of 6 or above are generally considered above average. The sten score is derived from the same percentile data but presents it in a simpler format that some hiring managers prefer.

One critical detail: SHL tests do not apply negative marking. You are not penalized for incorrect answers. This means you should always attempt every question, even if you are unsure. A guess has a 20 to 25 percent chance of being correct, depending on the number of answer options, which is always better than the zero percent chance of a blank answer.

The speed-accuracy balance is important. Answering 15 questions correctly out of 18 attempted will generally produce a better score than answering 10 questions correctly out of 18 attempted, but the optimal strategy varies depending on the adaptive nature of the test. In adaptive versions, getting early questions right is particularly valuable because it moves you into the higher-difficulty question pool, where correct answers carry more weight.

Time Management Strategies for SHL Numerical Tests

Time pressure is the defining challenge of SHL numerical reasoning tests. Most candidates who fail to reach their target score report that time, not difficulty, was the primary obstacle. Developing a reliable time management strategy is therefore just as important as sharpening your calculation skills.

Start by understanding your time budget. If your test has 18 questions and a 25-minute time limit, you have approximately 83 seconds per question. That sounds reasonable, but some questions will take 30 seconds while others will take two minutes. The key is to maintain awareness of your pace throughout the test without letting the clock create anxiety.

The two-pass approach is one of the most effective strategies for timed numerical tests. On your first pass, work through every question in order but set a personal time limit of approximately 90 seconds per question. If you reach 90 seconds and have not identified the correct approach, mark the question for review and move on. On your second pass, return to the marked questions and spend your remaining time on them. This ensures that you attempt every question and collect the easy points first.

Read the question before studying the data. Many candidates lose valuable seconds by carefully examining every row and column of a data table before reading what the question actually asks. Read the question first so you know exactly which data points you need. Then go to the table or chart and extract only the relevant values.

Estimate before calculating. Before performing a precise calculation, do a quick mental estimate. If the question asks for a percentage change and your rough estimate suggests the answer is around 15 percent, you can immediately eliminate answer options like 5 percent and 35 percent. This reduces the options you need to consider and can save significant time, especially when you are unsure of your exact calculation.

Watch for common time traps. SHL tests sometimes include questions where the data set contains far more information than you need. A table might have eight columns and six rows, but the question only requires values from two cells. Candidates who try to understand the entire data set before answering waste precious time.

Practice under timed conditions is essential. When you prepare for your aptitude test, always use a timer. Untimed practice builds your understanding of the material, but only timed practice builds the speed and decision-making habits you need on test day.

Common Mistakes and How to Avoid Them

SHL numerical tests are designed so that wrong answer options correspond to common calculation errors. The test developers know exactly which mistakes candidates typically make, and they include those incorrect values as answer choices. This means that arriving at an answer that matches one of the options does not guarantee you are correct.

Misreading the scale or units is one of the most frequent errors. A table might present revenue figures in thousands, but the question asks for the answer in millions. If total revenue is listed as 4,500 (in thousands), the correct answer in millions is 4.5, not 4,500. Always check the units in the data set header and the units requested in the question.

Applying the wrong base for percentage calculations catches many candidates. If a product's price increased from 80 to 100, the percentage increase is 25 percent (the change of 20, divided by the original value of 80). A common mistake is dividing by the new value instead of the original, which gives 20 percent. Both 20 percent and 25 percent will typically appear as answer options.

Reading the wrong row or column happens more often than most candidates expect, especially under time pressure. When a table has many rows with similar labels, like "Region A," "Region B," "Region A (adjusted)," it is easy to pull a value from the wrong line. Take an extra second to confirm you are reading the correct data point.

Rounding errors accumulate when a question requires multiple calculation steps. If you round intermediate results too aggressively, your final answer may be slightly off, and the wrong option may be closer to your result than the correct one. Keep at least two decimal places in intermediate steps and only round your final answer.

Ignoring conditional information in the question stem is another trap. A question might ask for the average revenue for quarters where revenue exceeded a certain threshold. If you calculate the average of all quarters instead of only the qualifying ones, you will get a plausible but incorrect answer.

SHL Numerical Tests Compared to Other Providers

SHL is not the only test provider used by employers. Understanding how SHL's numerical test compares to alternatives helps you contextualize your preparation, especially if you are applying to multiple companies that use different platforms.

Feature	SHL	Cubiks/Talogy	Aon/cut-e	Kenexa/IBM
Test name	Verify Numerical Ability	Logiks Numerical	Scales Numerical	Kenexa Prove It Numerical
Questions	18-25	20-24	37 (short subtests)	20-30
Time limit	17-35 minutes	20-25 minutes	12 minutes	20-30 minutes
Adaptive	Some versions	No	Yes	No
Calculator	Usually provided	Varies	Not provided	Varies
Data format	Tables, charts, graphs	Tables, word problems	Tables, simple charts	Tables, business scenarios
Answer format	Multiple choice (4-5)	Multiple choice (4)	Multiple choice (3)	Multiple choice (4-5)
Scoring	Percentile + sten	Percentile	Percentile + stanine	Percentile

The most notable differences are in pacing and question density. Aon's Scales Numerical test, for example, presents 37 questions in just 12 minutes, which works out to roughly 19 seconds per question. These questions are individually simpler than SHL questions, but the extreme time pressure creates a very different testing experience. SHL questions give you more time per item but demand more complex multi-step calculations.

Cubiks/Talogy tests tend to include more word-problem-style questions where numerical data is embedded in a text passage rather than presented in a clean table. Kenexa tests often focus on business-specific scenarios that mirror workplace tasks.

If you are applying to several companies simultaneously, it is worth checking which provider each one uses. Practicing across multiple formats builds versatile data-handling skills. Visit assessment-training.com for practice materials covering all major test providers.

How to Prepare Effectively for SHL Numerical Tests

Structured preparation is the single most reliable way to improve your SHL numerical reasoning score. Candidates who practice with realistic materials under timed conditions consistently outperform those who go in without preparation. Here is a step-by-step approach that covers both skill building and test-day logistics.

Step 1: Confirm your test details. Check your invitation email for the test provider (SHL), the specific test name (e.g., Verify Numerical Ability or Interactive Numerical), the time limit, whether a calculator is permitted, and any proctoring requirements. This information shapes everything else in your preparation.

Step 2: Assess your baseline. Take an untimed practice test to identify your strengths and weaknesses. Note which question types you find straightforward and which ones trip you up. Most candidates discover that they are comfortable with basic data reading but struggle with multi-step percentage calculations or weighted averages. Your baseline assessment tells you where to focus your study time.

Step 3: Build your core skills. Work through practice questions for each question type. Focus especially on percentage changes, ratio comparisons, and data interpretation from charts. Use the SHL numerical reasoning practice tests to practice with questions that match the format and difficulty level of the real test.

Step 4: Practice under timed conditions. Once you are comfortable with the question types, switch to timed practice. Set a timer for the same duration as your actual test and work through a full set of questions without pausing. This builds your pacing instincts and trains you to make quick decisions about when to skip and return to a difficult question.

Step 5: Review your errors. After each practice session, go through every question you got wrong and understand exactly where your reasoning or calculation went astray. Did you misread the data? Use the wrong formula? Make an arithmetic error? Categorize your mistakes so you can watch for patterns.

Step 6: Simulate test-day conditions. In your final preparation sessions, replicate the actual testing environment as closely as possible. Sit at a clean desk, use only the tools you will have during the test, close all distractions, and complete the practice test from start to finish without interruption. If your test will be proctored, practice with your webcam on.

Step 7: Prepare your technical setup. If you are taking the test online, run SHL's system check tool at least 48 hours in advance. Verify that your browser, webcam, and internet connection meet the requirements. Have a backup plan in case of technical issues, such as a mobile hotspot or an alternative device.

What Employers Look for in SHL Numerical Results

Employers do not just look at whether you passed or failed the SHL numerical test. Your score feeds into a broader assessment of your suitability for the role, and understanding what employers are evaluating helps you approach the test with the right mindset.

First, employers use your percentile score to make an initial screening decision. Most companies set a minimum threshold, and candidates who fall below it are typically removed from the process regardless of how strong the rest of their application might be. This threshold varies by industry and role. Investment banking and strategy consulting roles at firms like Goldman Sachs, McKinsey, and BCG tend to set high thresholds, often the 70th or 80th percentile. Operations, marketing, and HR roles may accept lower percentiles.

Second, some employers look at your performance pattern across different question types. SHL's reporting tools can break down your results by category, showing whether you performed better on data interpretation than on calculation-heavy questions, or vice versa. This information helps hiring managers understand your analytical profile and how it aligns with the specific demands of the role.

Third, if you take an online assessment followed by a verification test at the employer's office, the consistency between your two scores matters. A significant drop between your at-home score and your in-person score raises questions about the integrity of the first result. Employers expect some variation due to test anxiety and different conditions, but a gap of more than one sten score typically triggers closer scrutiny.

Fourth, your numerical reasoning score is usually considered alongside your performance on other assessments, such as verbal reasoning, logical reasoning, or situational judgment tests. An employer hiring for a data-heavy finance role will weight numerical reasoning more heavily than verbal reasoning. An employer hiring for a communications role will weight them differently. Understanding the role you are applying for helps you allocate your preparation time appropriately.

Companies that use SHL numerical tests as part of their graduate recruitment include the Big Four accounting firms, major banks, management consultancies, FMCG companies like Unilever and Nestle, and technology firms. The test is particularly prevalent in the United Kingdom, Australia, and across Europe, though it is also widely used in North America and Asia.

Frequently Asked Questions

Are SHL numerical tests adaptive?

Some SHL numerical tests use adaptive technology where the difficulty of each question adjusts based on your previous answers. If you answer correctly, the next question becomes harder, and if you answer incorrectly, the next question becomes easier. However, not all SHL numerical tests are adaptive. Fixed-form tests present the same set of questions to every candidate. Your invitation email or the test instructions will usually indicate which format applies to your assessment.

Can I use a calculator in SHL numerical tests?

It depends on the specific test version your employer has selected. Many SHL numerical reasoning tests provide an on-screen calculator within the test platform. Some versions allow you to use your own physical calculator, while others do not permit any calculator use at all. Always read the instructions carefully before starting. If the test does not provide or allow a calculator, the questions will be designed so that the calculations can be completed without one.

How is the SHL numerical test scored?

SHL uses norm-referenced scoring, meaning your raw score is compared to a benchmark group of previous test-takers. Your result is reported as a percentile rank. For example, scoring in the 65th percentile means you performed better than 65 percent of the norm group. Employers typically set a minimum percentile threshold for each role. Some SHL tests also produce a sten score, which places your performance on a standardized scale from 1 to 10.

How long does the SHL numerical reasoning test take?

Most SHL numerical reasoning tests contain between 18 and 25 questions with a total time limit of 17 to 35 minutes. The exact length depends on which version your employer has chosen. The SHL Verify Interactive numerical test typically allows around 25 minutes for 18 questions. You should expect to spend roughly 60 to 90 seconds per question on average.

What happens if I run out of time on an SHL numerical test?

Unanswered questions are marked as incorrect when the timer expires. SHL does not penalize you for guessing, so if you are running low on time, it is better to select an answer for every remaining question rather than leaving them blank. The platform will auto-submit your test when the time limit is reached, so you cannot continue working after the clock runs out.

Can I retake an SHL numerical reasoning test if I score poorly?

Retake policies are set by the employer, not by SHL. Most companies enforce a waiting period of six to twelve months before allowing a candidate to retake the same assessment. Some employers may allow an earlier retake if there were documented technical issues during the first attempt. Contact your recruiter directly to ask about the specific retake policy for your application.
