📝 Assessments

Civil Service Verbal Test cognitive

Read a text passage and determine whether statements are true, false, or cannot say based on the information provided. GOV.UK states there is no time limit.

Measures: Reading comprehension, logical deduction, evidence-based judgement

  • Base answers only on the passage — not general knowledge
  • True = clearly supported by the text
  • False = contradicted by the text
  • Cannot Say = not enough information in the passage to decide
Civil Service Numerical Test cognitive

Interpret data from graphs, tables, and numerical information, then answer multiple-choice questions. GOV.UK states there is no time limit.

Measures: Data interpretation, calculation ability, evidence-based numerical reasoning

  • Read graph labels and axes carefully
  • Check units and time periods
  • Use estimation to verify calculations
  • Take your time — there is no time limit
Civil Service Judgement Test situational judgement

Workplace scenarios testing professional judgement in Civil Service contexts. Presents situations and asks candidates to rate or rank response options.

Measures: Workplace judgement, decision-making, professional behaviours, stakeholder management

  • Think about what a good civil servant would do
  • Consider multiple stakeholders (public, colleagues, ministers)
  • Focus on proportionate and professional responses
  • Consider the Civil Service values: integrity, honesty, objectivity, impartiality
Work Strengths Test personality

Assessment exploring work preferences, natural strengths, and what motivates you. Helps identify fit with role requirements.

Measures: Work preferences, natural strengths, motivation, role fit

  • Answer authentically about what genuinely motivates you
  • There are no right or wrong answers
  • Be consistent in your responses
  • Think about your actual work preferences, not idealized ones

🎤 Interviews

Behaviour Interview

Assessed against named behaviours from the Civil Service Behaviours framework (e.g., Making Effective Decisions, Delivering at Pace, Seeing the Big Picture). Grade-level expectations apply.

Format: Structured STAR-based questions on specific Civil Service behaviours

  • Check the job advert for exactly which behaviours are assessed
  • Match your evidence to the grade level (EO is different from G7)
  • Use the Civil Service behaviour indicators as a guide
  • Prepare one strong example per behaviour, with a backup
Strengths Interview

Explores what you naturally gravitate toward, what energizes you, and what you find challenging. Less about rehearsed examples, more about authentic self-awareness.

Format: Questions about natural preferences and what energizes you

  • Don't over-prepare scripted answers — authenticity is key
  • Think about what genuinely energizes you at work
  • Be honest about areas you find less energizing
  • Show how your strengths connect to the role

❓ Frequently Asked Questions

Are Civil Service verbal and numerical tests timed?
GOV.UK guidance states there is no time limit for the Civil Service Verbal and Numerical tests. Take your time and focus on accuracy.
What framework does the Civil Service use?
The Civil Service uses Success Profiles, made up of Ability, Technical, Behaviours, Strengths, and Experience. Each vacancy specifies which elements are assessed.
Are online tests the only selection method?
No. GOV.UK states tests are not the only form of selection and may be used alongside applications, technical evidence, interviews, and other methods.
Do I need different examples for different grades?
Yes. The same behaviour (e.g., 'Making Effective Decisions') has different expectations at EO compared to G7. Check the behaviour indicators for your target grade.
Can I ask for help during the tests?
No. GOV.UK states answers must be your own and candidates must not ask for help. The hiring manager may require a supervised retake.
