What Is The Civil Service Numerical Test?
The Civil Service Numerical Test (CSNT) is a psychometric test designed to assess your numerical reasoning skills, evaluating your ability to interpret numerical information, perform calculations, and solve mathematical problems.
The test is not timed, but most candidates take between 15 and 45 minutes to complete it. Your score will not be impacted by how long you take, and you are allowed to use a calculator.
Questions range from basic and intermediate to advanced. For each, you'll be presented with graphs and tables that contain numerical information, followed by a multiple-choice selection of answers.
Let's take a look at some Civil Service Numerical Test sample questions for each of the different difficulty levels:
CSNT Sample Question #1
Let’s start with an easy one.
Take a look at the image below and then answer the question that follows.
If 12,000 people participated in this survey, how many of them chose soup?
- A. 960
- B. 1,080
- C. 1,200
- D. 1,360
- E. 1,420
Choose your answer before looking at the explanation below.
The correct answer is B: 1,080
To answer this question, you first need to examine the chart:
- The left column shows the food preferences (in percentages) for male respondents.
- The middle column shows the preferences for female respondents.
- The right column shows the combined preferences for all respondents (both male and female).
You've been asked to find the number of people who selected soup as their preferred food. Therefore, the relevant column is the right one.
9% of the respondents (both male and female) chose soup.
To find the number of people:
9% of 12,000 is calculated as: 2,000 × 0.09 = 1,080 people.
Therefore, the correct answer is B.
CSNT Sample Question #2
Now, let’s move on to something a bit more complicated.
Study the table and answer the question that follows:
What is the value of 500 British pounds in Brazilian Real, using the Yen exchange rate?
- A. 1,900
- B. 19,000
- C. 100,000
- D. 1,000,000
- E. None of these
Choose your answer before looking at the explanation below.
The correct answer is A: 1,900
First, convert 500 British pounds (GBP) to Yen.
From the table, we know that 1 Yen is equal to 0.005 GBP, so:
1 GBP = 1 ÷ 0.005 Yen = 200 Yen.
Therefore, 500 GBP = 500 × 200 = 100,000 Yen.
Next, convert the 100,000 Yen into Brazilian Real (BRL) using the exchange rate from Yen to BRL in the table:
100,000 × 0.019 = 1,900 BRL.
Therefore, the correct answer is A.
Solving tip: To save time, you can directly calculate the GBP to BRL rate. Since 0.005 GBP = 0.019 BRL, the GBP to BRL rate is 0.019 ÷ 0.005 = 3.8. Then, multiply this by 500: 500 GBP = 500 × 3.8 = 1,900 BRL.
CSNT Sample Question #3
Finally, let's work on a more advanced Civil Service Numerical Test question.
Consider the data below and answer the question that follows:
*GDP -Gross Domestic Product
In 2010 there were 5,880,483 more women than men. What was the total GDP in 2010?
- A. 333,450,000
- B. 257,831,770
- C. 512,475,987
- D. 490,887,252
- E. 527,479,325
Choose your answer before looking at the explanation below.
The correct answer is E: 527,479,325
According to the table, the gender ratio of men to women in 2010 was 44% to 56%, which adds up to the total population, or 100% (including both men and women).
This means the number 5,880,483 represents the difference between the genders: 56% - 44% = 12% more women than men. You can also calculate this using decimals: 0.56 - 0.44 = 0.12.
If 12% of the total population equals 5,880,483, we can use the rule of three to find the total population:
- 12% → 5,880,483
- 100% → y
This can be set up as:
- (12 ÷ 100) → 5,880,483
- (100 ÷ 100) → y
Which simplifies to:
- 0.12 → 5,880,483
- 1 → y
Now, solve for y:
y = (1 × 5,880,483) ÷ 0.12 = 5,880,483 ÷ 0.12 = 49,004,025
So, the population in 2010 was 49,004,025.
The table also shows that the GDP per capita in 2010 was $10,764.
Now that we know the population size is 49,004,025, we can calculate the total GDP in 2010:
49,004,025 × 10,764 = $527,479,325
Therefore, the correct answer is E.
The Civil Service Numerical Test questions are adaptive, meaning the difficulty of the questions will change depending on your performance.
- If you answer a question correctly, the next one will be more difficult.
- If you answer incorrectly, the next question will be easier.
This self-adjusting style ensures that the test provides an accurate measure of your abilities, offering a challenge no matter your mathematical skill level. By the end of the test, it'll have converged on a level of difficulty that best represents your true ability.

What Is A Good Score On The Civil Service Numerical Reasoning Test?
Your Civil Service Numerical Test score is based on the number of questions you answer correctly, with each question contributing to your score according to its difficulty level.
- Once you've completed the test, your score is compared to a group of candidates at the same occupation and organisational level as the position you're applying for.
- Your score is then presented as a percentile out of 100%. For example, if your percentile score is 45, it means you scored higher than 45% of the candidates in the comparison group.
- After the test deadline, the aggregate of all candidates' scores determines the test's passing mark.
If you meet or exceed the minimum pass mark, your score will be banked for six months, allowing you to apply for other Civil Service positions without retaking the test. If your score is below the pass mark, or if more than six months have passed since you took the test, you'll need to retake it when applying for future positions.
Civil Service Numerical Test Tips
The numerical test Civil Service UK candidates take can bring on real test anxiety, particularly when a role is at stake.
A few practical habits can help you approach it calmly and perform at your best:
- Don’t rush: Since the Civil Service Numerical Test doesn't have a time constraint, and how long it takes you to complete doesn’t affect your score, you can really take it slow and not rush to submit your answers. Read the questions carefully, pay attention to the data, validate your calculations, and go through all the possible choices before moving on to the next question.
- Eliminate unnecessary information: Graphs and table-based questions can be loaded with details irrelevant to the questions you’ve been asked. Read the question thoroughly before approaching the data. This'll make it easier for you to locate the relevant information.
- More than numbers: The numbers are not all that matters. The purpose of this test is to see how you use the numbers to reach your answer. Make sure you master all the basic calculation methods so you'll be able to identify and perform the one you need.
To succeed in the Civil Service Numerical Test, you need strong maths at every difficulty level and familiarity with the specific question types and formats you'll face.
How To Prepare For The Civil Service Numerical Test
Achieving a high score in the Civil Service Numerical Test may come down to basic maths, but there are also a few other factors at play.
Here’s how to best prepare for the Civil Service Numerical Test:
- Refresh your mathematical skills: Start by revisiting basic arithmetic, percentages, ratios, and other core concepts that may appear in the test.
- Familiarise yourself with question formats: Understanding the types of questions you’ll encounter, such as data interpretation, word problems, and number sequences, is key to performing well.
- Practise different difficulty levels: The test will feature a range of questions, from easier to more challenging problems. It’s essential to build your confidence in solving both simple and complex calculations.
- Work efficiently, not just accurately: The test is untimed, but building familiarity with common question formats means you'll spend less time working out how to approach each one, leaving more time to check your answers.
- Master solving techniques: Learn how to break down complex questions, use quick mental maths techniques, and apply logical reasoning to arrive at accurate answers.
