The test library
What each family of tests measures and how it is built.
-
What tests are available
The six families in the library, how to browse them, and what every test's own guide will tell you.
-
Reasoning and aptitude tests
What this family measures, which test fits which kind of work, and how to read a score from one.
-
Workplace skills tests
The situational judgement family, what it actually asks candidates to do, and why it is the most misread set of tests in the library.
-
Programming tests
What these tests are, what they deliberately are not, and how to use them in a technical hiring process.
-
Software skills tests
Tests on the tools people use daily, when a tool test beats a reasoning test, and how to keep them fair.
-
Language tests
What the language family covers, the difference between a language test and an English grammar test, and the legal care they need.
-
Personality, drives and interests
The three unscored questionnaires, what each one asks, and where they belong in a hiring process.
-
How our tests are written
Where the questions come from, what the difficulty labels and averages are based on, and what we do not claim.
