Checked 14 October 2026. The list of online tests is from the Civil Service Careers online-tests page for 2027 entry, read on 14 October 2026 and fetched again the same day. The “Using data” wording is from the process-video transcripts on the application-process and assessment-centre pages, read the same day. Assessment-centre details are from the Fast Stream Assessment Centre guide. Civil Service Numerical Test details are from GOV.UK guidance. Scheme entry requirements are from our copies of the scheme pages saved on 28 September 2026. Test line-ups change between campaigns.
For 2027 entry, the official Fast Stream online-tests page lists two online tests, and neither is a numerical test. They are Work-based scenarios and the Case Study assessment, and both ask you to judge actions in work situations. That is the plain answer, and it comes with one complication that you should know about before you rely on it: a different official page still names an assessment called “Using data” in a video transcript. This guide prints both statements, says which page describes what, and then shows where numbers do turn up in the Fast Stream process, because they do.
A note from us
Applying to the Fast Stream is a big step, and there is a lot to take in. We have tried to set out what is published as plainly as we can. Take it one section at a time, and come back whenever it helps.
Civil Service Careers, online-tests page, application-process page and Fast Stream Assessment Centre guide (read 14 October 2026).
What the official online-tests page lists
| Official wording (2027 entry) | What it tells you |
|---|---|
| “There are 2 online tests to complete:” | Two tests, by count. |
| Work-based scenarios | Test 1. “This test measures interpersonal skills.” |
| Case study assessment | Test 2. “This test assesses your decision-making and your ability to adapt to changing circumstances.” |
| “The tests are untimed, so you can work at your own pace.” | No timed calculation under pressure is described. |
The page describes each of the two tests in its own section: 12 scenarios for the first, and 7 pieces of background information followed by 24 situations for the second. There is no third section. The words “numerical”, “verbal” and “data” do not appear in the description of either test. Our copy of the same page from the last campaign, saved on 28 September 2026, also said there were 2 online tests, with the same two names. So this is not a change made for 2027.
The one official mention of a data test: “Using data”
The application-process page carries a short video about the four stages, with a transcript. The transcript does not match the online-tests page, and the same transcript is worded differently on a second page. Here are all three statements.
| Official page | What it says | Tests named |
|---|---|---|
| Online tests | “There are 2 online tests to complete:” Work-based scenarios; Case study assessment | 2 |
| Understanding the application process (video transcript) | “The first stage consists of 2 online assessments: Using data, Work-based scenarios and Case study assessment.” | 3, although it says 2 |
| Assessment centre (the same video transcript) | “The first stage consists of 3 online assessments: Using data, Work-based scenarios and Case study assessment.” | 3 |
We do not resolve this, because no official page does. What we can say is narrower. The online-tests page is the page written for this stage, and it describes two tests in detail and no third. No Fast Stream page we read describes a “Using data” test: there is no section for it, no example question and no scale. The transcript is the only place the name appears. Our reading is that the video was made for an earlier version of the process and the transcript was only partly corrected, which would explain a sentence that says 2 and then lists three. That is a guess about the cause, and we label it as one.
What to do about the conflict (our advice)
- Treat the online-tests page as the working answer: prepare for two judgement tests.
- When your tests are released, count what your applicant homepage shows. If a third test is there, the homepage is right and this guide is out of date.
- Do not skip basic comfort with tables and percentages on the strength of the two-test list. You will need it at the assessment centre in any case.
Where numbers are tested instead
| Stage | What the official pages say | Numbers involved |
|---|---|---|
| Online tests | Two judgement tests. No numerical content is described. | None described |
| Assessment centre: Written Exercise | You play a fast streamer overseeing a project, with 55 minutes to review information and complete 4 written tasks. A tip for the day is to “uncover key patterns within the data”. The published example pack includes an item of opinion polls. | Reading data inside a written brief |
| Assessment centre: Oral Briefing Exercise | “You will analyse data and brief a director (portrayed by an assessor) on your findings.” 45 minutes to review the project documents. The published example gives items “in graph and table format”, and a good response should “use and refer to data to explain your decision”. | Percentages, tables and graphs to read and compare |
| Assessment centre: tips for the day | Have some paper, pens and a calculator within reach for making notes. | A calculator is expected to be useful |
| Final Selection Board | Tests skills and strengths specific to your chosen scheme. Details come in the guide linked in your invitation. | Depends on the scheme; not published |
The numbers at the assessment centre are not a reasoning test with right and wrong options. They are evidence inside a brief. The published Oral Briefing example gives turnout and polling figures as percentages, in graphs and tables, and asks for a recommendation. What is being assessed, in the guide’s words for the “Think” dimension, is how you gather, process and analyse information. In practice that means reading a table correctly, comparing two percentages without misreading the base, and saying what the figures do and do not support.
Numerate degrees: an entry requirement, not a test
Some schemes ask for numeracy before you apply, through the degree rule. That is a separate matter from the online tests, which are the same two tests whatever scheme you choose.
| Scheme | Entry requirement on the scheme page (our copy of 28 September 2026) |
|---|---|
| Government Operational Research Service | A 2:1 or higher, or degree apprenticeship, in a highly numerate degree subject; or a 2:2 with a highly numerate postgraduate degree (subjects like maths, statistics and physics; for mixed degrees, at least 50% should be in a highly numerate subject) |
| Government Statistical Service | A first or second-class honours degree, 2:1 minimum, in a numerate subject containing taught statistical content; or a higher degree, for example MSc or PhD, in a subject containing formal statistical training |
Other analytical schemes have subject rules of their own, in economics, social research or science and engineering. All of them are in our schemes and eligibility guide, with a checker. Read the scheme page itself before you choose preferences.
The Civil Service Numerical Test is a different test
Much of what is written about a “Fast Stream numerical test” is really about the Civil Service Numerical Test, one of the standard tests used in ordinary Civil Service job adverts. GOV.UK lists 8 commonly used tests and says the job advert will say whether you may be asked to complete one or more of them. (The Civil Service Careers assessments page lists 7; the difference is the Styles Assessment, which only the GOV.UK list includes. The Numerical Test is on both.) If you are also applying for other Civil Service jobs this autumn, you may well sit it there.
| Point | Civil Service Numerical Test (GOV.UK guidance) |
|---|---|
| What it measures | The ability to perform calculations, and evaluate and interpret numerical information to solve problems |
| Format | Graphs, tables or other numerical information, followed by a question with several possible answers; you identify the correct one |
| Timing | Not timed; most people take between 15 and 45 minutes, and the score is not affected by how long you take |
| Length | The test adapts to your performance, so it can vary in length |
| Navigation | Answer every question; you cannot skip or go back |
| Aids | You may wish to have some rough paper, a pen and a calculator to hand |
| Official practice | A Civil Service Numerical practice test, which is not scored |
| Is it part of the Fast Stream online tests? | Not according to the Fast Stream online-tests page for 2027 entry, which lists Work-based scenarios and the Case study assessment only |
The official numerical practice test on GOV.UK is still worth an hour for a Fast Stream candidate. It is the closest official material to the table-reading the assessment centre asks for, even though it belongs to a different test and is not scored.
How to prepare for the numbers you will actually meet
Our advice
- Online tests: spend your time on the rating scale and on scenarios, not on numerical reasoning drills. The two listed tests are about judgement.
- Assessment centre: practise reading a table or chart and saying one true sentence about it in under a minute. The Oral Briefing gives you 45 minutes to prepare and 10 to brief.
- Percentages: be sure of the difference between a percentage of a group and a percentage point change. Briefing material is full of both.
- Keep a calculator and paper to hand on the day, as the guide advises.
- Other Civil Service applications: if an advert lists the Numerical Test, take the GOV.UK practice test first.
Suggestions from us. Only the calculator line and the timings are official.

Frequently asked questions
Is there a numerical test in the Fast Stream for 2027 entry?
The official online-tests page lists two online tests, Work-based scenarios and the Case Study assessment, and neither is a numerical test. A video transcript on the application-process page also names an assessment called Using data, which no page describes.
What is the Fast Stream Using data test?
It is named only in the process-video transcript, which says the first stage consists of Using data, Work-based scenarios and Case study assessment. The online-tests page lists only the last two, and no official page describes a Using data test.
Does the Fast Stream have a verbal reasoning test?
Not on the official online-tests page for 2027 entry. It lists Work-based scenarios and the Case Study assessment, which are both judgement tests about work situations.
Do I need maths for the Fast Stream?
You need to be comfortable reading tables, graphs and percentages. The assessment centre’s Oral Briefing Exercise is described as analysing data and briefing a director, and its published example gives information in graph and table format.
Can I use a calculator in the Fast Stream?
For the assessment centre, the official guide advises having some paper, pens and a calculator within reach. No page says anything about calculators for the online tests.
Is the Civil Service Numerical Test part of the Fast Stream?
Not according to the Fast Stream online-tests page for 2027 entry. The Civil Service Numerical Test is one of the standard tests used in ordinary Civil Service job adverts, and the job advert says whether it applies.
Which Fast Stream schemes need a numerate degree?
The Government Operational Research Service asks for a highly numerate degree subject, and the Government Statistical Service asks for a numerate subject containing taught statistical content. Other analytical schemes have their own subject rules; check each scheme page.
How long is the Civil Service Numerical Test?
GOV.UK says it is not timed and that most people take between 15 and 45 minutes. The test adapts to your performance, so its length varies.
Good luck from all of us
Whatever stage you are at, getting this far takes real effort, and that is worth being proud of. Prepare at a pace that works for you, check the official Civil Service Careers pages for anything that decides your application, and look after yourself along the way. We are wishing you every success.
Great works are performed not by strength, but perseverance.
