Is there a Civil Service exam? Tests, eligibility and how selection works

How Civil Service selection works

By law, people must be appointed to the Civil Service on merit, on the basis of fair and open competition. The Civil Service Commission's Recruitment Principles explain what that means: the best available person is appointed against the criteria published for the role, assessments are objective and consistent, and opportunities are advertised publicly. There are a small number of defined exceptions, such as some short-term appointments.

A typical process looks like this:

1. Find the job on Civil Service Jobs and read the full advert.
2. Apply. Depending on the role this may include a CV, a personal statement and examples of your experience.
3. Sift and shortlisting, where you may be asked to take an online test.
4. Assessment: an interview, presentation, online test or assessment centre. Interviews usually last 30–60 minutes (official sources vary, so check your invitation) and may be in person, by video or pre-recorded.
5. Outcome and feedback.

Success Profiles: what you're assessed on

Most Civil Service recruitment uses the Success Profiles framework, which has five elements:

• Behaviours: the actions and activities that lead to effective performance
• Strengths: the things you do regularly, do well and that motivate you
• Ability: your aptitude or potential to perform to the required standard
• Experience: knowledge or mastery gained through involvement in an activity or subject
• Technical: specific professional skills, knowledge or qualifications

Each advert says which elements, and which of these nine Behaviours, will be assessed: Seeing the big picture, Changing and improving, Making effective decisions, Leadership, Communicating and influencing, Working together, Developing self and others, Managing a quality service, Delivering at pace.

Civil Service online tests

Some jobs use online tests, and the advert tells you if so. GOV.UK says no specialist knowledge or experience is needed. It lists eight commonly used tests, each with an official practice version:

• Civil Service Verbal Test
• Civil Service Numerical Test
• Civil Service Judgement Test
• Civil Service Management Judgement Test
• Civil Service Work Strengths Test
• Styles Assessment for Behaviours
• Customer Service Skills Test
• Casework Skills Test

The Civil Service Judgement Test is an online situational judgement test based on the Civil Service Behaviours. It isn't timed, though most people take two to four minutes per scenario, and you may be asked to retake it under supervision if you're invited to interview. Scores are compared with other candidates as percentiles. Practise only with the official tests linked from GOV.UK.

The Fast Stream graduate programme has its own online tests and assessment centre.

Who is eligible to apply?

Nationality

Under the Civil Service Nationality Rules, UK nationals can in principle work in any Civil Service post. Irish nationals, Commonwealth citizens and British protected persons can work in all posts that aren't "reserved". EU, EEA and Swiss nationals generally need settled or pre-settled status under the EU Settlement Scheme (or another qualifying status). GOV.UK says about 75% of posts are open to Commonwealth and EEA nationals. "Reserved" posts, such as all posts in the security and intelligence services, are open to UK nationals only. Each advert states its nationality requirements.

Age

Civil Service apprenticeships are open to anyone aged 16 or over who meets the nationality rules.

Security checks

All civil servants go through the Baseline Personnel Security Standard (BPSS), which GOV.UK says is not a formal security clearance. Some roles also need national security vetting. The levels include Counter Terrorist Check (CTC), Security Check (SC) and Developed Vetting (DV), the last two for roles with regular access to SECRET and TOP SECRET material respectively. The advert says what's required, including any UK residency requirement.

Can you use AI to apply?

The official candidate guidance says AI tools can help you refine and clarify your ideas, research public information, check spelling and grammar, and structure your examples, for example in the STAR format. But they must not be used to inflate or invent your skills and experience, to create generic answers, to complete tests such as situational judgement or numerical tests, or to generate answers during a live or pre-recorded interview. Applications may be rejected where AI is used inappropriately, and you confirm that what you submit is true and accurate.

That's why our approach is to help you find and organise your own real examples, never to write them for you.
