Why does a score differ from CAT4, GL or other providers?

When comparing scores between Quest Admissions and other providers, you can expect to see a correlation in scores and ranking, but often a difference in the numbers themselves. There are two main reasons for this.

Content. Quest Admissions and other assessments offer fundamentally different tests, with different content. There will be overlapping content domains, but each test also has elements unique to it. For example, Quest Maths uses primary maths challenge style questions, and Quest offers subjects such as Puzzles and Problem Solving and Creative Comprehension that other providers do not.

Standardisation. Quest standardises against a sample of applicants who apply to independent schools. Many other providers standardise against a mixed population that includes both independent and state sector pupils. Comparing against a higher-attaining sample also produces a slightly lower standardised score due to the academic standard, which also attributes to any obervable difference in scoring.
