RANRA Indepth

The Rust Advanced Numerical Reasoning Appraisal (RANRA) assesses the ability to recognise, understand and apply mathematical and statistical reasoning. It is the result of a large study of both verbal and numerical reasoning skills undertaken in the UK in 2001.

Users of the Watson Glaser Critical Thinking Appraisal in the UK had frequently commented on their wish to assess numerical reasoning as well as critical thinking. This led to the development of RANRA as a companion numerical reasoning test for the W-GCTA.

RANRA builds on and extends the critical thinking skills appraisal available through use of the W-GCTA, with which it was originally co-normed in a standardisation involving a sample of over 1500 test takers in the UK working population. RANRA is available in paper and pencil and online versions, both requiring supervised administration.
