UN online pre-screening tests: aptitude, psychometrics and what to expect
Last updated 2 August 2026
The tests are not an intelligence exam. They are a filter, and filters can be prepared for.
This is lesson 6.1 of UN Career Academy, module 6: Assessments and Written Tests. It is free to watch in full, with no account and no payment. The narration follows the video, less the closing pointer to the lessons that come after it.
Transcript
Online pre-screening tests are now a standard part of the application process at several major UN agencies. They come early in the selection process — often before any human reviewer has seen your full profile — and they carry real weight in shortlisting decisions. Yet they are almost entirely absent from standard UN career guidance.
This video tells you which agencies use them, what the tests look like, and how to prepare.
UNDP uses cognitive and personality assessments for many professional-level posts, delivered through third-party testing platforms. These are typically deployed after initial application screening and before the written assessment or interview stage.
UNICEF uses assessment tools at the roster and specific vacancy stages — including personality and situational judgement instruments for professional posts.
WHO uses psychometric tests for some headquarters and field roles, particularly at the P-3 to P-5 level.
The UN Secretariat uses online assessments selectively — not universally, but for specific job families and vacancy types. When used, they are administered through Inspira or third-party platforms linked from Inspira.
Not every vacancy at these agencies includes an online pre-screening test. But these assessments are sufficiently common — and sufficiently consequential — that every candidate should understand what they are and have done some preparation.
Type 1: Cognitive and Aptitude Tests.
These measure numerical reasoning, verbal reasoning, and abstract or logical reasoning. They are timed — typically fifteen to thirty minutes, with thirty to fifty questions. The specific vendors agencies use change — your course resources include current practice links.
The key features: these tests are designed to be difficult to complete in full in the time allowed. Speed and accuracy both matter. Incorrect answers typically count against you (the scoring model varies — verify before the test if possible). Numerical and verbal reasoning questions are the most common; abstract reasoning (pattern recognition in shapes or sequences) appears in cognitive general ability tests.
Type 2: Personality and Behavioural Assessments.
These are untimed — the instruction to complete them 'as quickly as possible' should be understood as 'in one sitting, without overthinking.' There are no objectively wrong answers, but response inconsistency matters.
The purpose: not to find candidates with the 'right' personality, but to identify candidates whose self-reported behavioural tendencies align with the competency profile the agency is recruiting for, and to flag response patterns that suggest inconsistency or impression management.
The preparation instruction for personality assessments: do not try to game them. Respond as you would genuinely behave in the described situations. Attempts to identify and mirror a 'desired' profile typically produce inconsistent responses, which the algorithm identifies. Be genuine; be consistent.
Type 3: Situational Judgement Tests (SJT).
These present a series of realistic workplace scenarios and ask you to choose the best and/or worst response from a set of options. They measure professional judgement — specifically, whether your instinctive professional responses align with the agency's values and competency framework.
The most important preparation step: before sitting an SJT, find the competency or values framework the organisation uses — the job opening lists it — and read it. The SJT is scored against it. If the agency values 'client orientation', an SJT scenario about competing priorities will have a 'best' answer that prioritises the stakeholder relationship over internal convenience. If you have not read the framework, you may answer based on intuitions that do not match the agency's values.
For cognitive tests:
Practice with free sample tests before any online assessment. The format, pacing, and difficulty level are consistent across administrations. Thirty minutes of daily practice for one to two weeks before an expected assessment measurably improves performance — not by changing your intelligence, but by improving your familiarity with the format and your pacing strategy.
Current practice links are maintained in Downloadable Resource 4, Agency Portal Quick Reference — the resource is kept up to date as vendors change.
Timed practice under realistic conditions — no interruptions, no note-referencing — is more valuable than untimed review of sample questions.
For personality assessments:
No specific preparation is required or beneficial. Respond as you would genuinely behave. Be consistent — if you describe yourself one way early in the assessment, maintain that self-description throughout. A fifteen-minute sitting with no overthinking produces the most accurate and consistent profile.
For situational judgement tests:
Read whichever competency or values framework the organisation uses before you sit — the job opening lists it. Read the agency's specific values statement if one exists. The 'correct' answer in an SJT is the one that best reflects those values.
One final point worth stating plainly:
Online pre-screening assessments are frequently introduced in the application email or portal notification as 'a brief online exercise' or 'an online task that should take twenty to thirty minutes.' This framing understates their significance.
In many recruitment processes, the cognitive and SJT scores contribute directly to the shortlist score. A candidate who performs poorly on the cognitive assessment may not advance to the written assessment stage regardless of the strength of their application. A strong motivation statement does not compensate for a below-threshold test score.
Treat every online assessment as if it is the first hurdle between your application and an interview. Because it often is.
Online pre-screening tests are used by UNDP, UNICEF, WHO, and selectively by the Secretariat. Three types: cognitive/aptitude (timed, practice-able), personality/behavioural (untimed, be genuine and consistent), and situational judgement (scored against whichever framework the organisation uses — find it in the JO and read it first). Treat them as seriously as the interview.
