What is a Saville assessment?

A Saville assessment is an online assessment from Saville Assessment, the UK publisher founded by Professor Peter Saville and independently owned since 2023, when Willis Towers Watson sold the business. Its aptitude range includes standalone tests and Swift combinations. Current Swift Analysis combinations take 18 to 24 minutes, while Swift Comprehension takes 9.5 to 16 minutes. The Wave questionnaires cover workplace personality and styles.

Which Saville test you sit depends on the employer and the role: an entry-level position will not be given the same assessment as a graduate or managerial one.

How a Saville test works

Four things to know before you sit one. Timings and difficulty vary with the level of the role.

FormatStandalone tests or a Swift blend
Each aptitude can be sat on its own or combined into a Swift assessment covering several skills in one timed session. Supervised versions are shorter and sat at a test centre or in the workplace; unsupervised ones are taken online. Workplace English is always a standalone test, never part of a Swift assessment.
PaceTiming follows the Swift version
Swift Analysis takes 18 to 24 minutes, Comprehension 9.5 to 16, Technical 10, Global 12 and Executive 18. Standalone aptitude tests have separate limits.
DifficultyTwo depths, set to the role
Analysis level is for graduate and professional roles, Comprehension level for entry level. The tests ask you to extract the right data point or judge a statement from the passage alone, not to perform complex arithmetic.
ScoringA percentile against professionals
Your raw score becomes a percentile against an international norm group of professionals, and the employer sets the bar. There is no universal pass percentile across employers.
