How the IDS-2 can support course programmes

Backed up by the latest UK research

The IDS-2 is the most comprehensive diagnostic assessment available, reinforced by the latest research from Oxford Brookes University, standardised with UK norms from 2020.

What makes the IDS-2 unique?

  • Supports a wider age range (from 5;0 to 20;11)
  • Assesses both intelligence and development
  • Covers every area of the CHC model of intelligence – not just selected areas
  • Offers more intelligence testing options – from quick IQ screening to general intelligence testing and an in-depth IQ profile
  • Provides efficient administration with a unique frustration-minimizing inversion rule (rather than a classical inversion rule)
  • Employs norms developed through state-of-the-art continuous norming, so you don’t have to rely on small sub-samples for each age group
  • Includes online scoring with each purchase of the record forms

Broader scope of intelligence testing

The table to the right shows commonly used intelligence assessments and how they map onto the eight factors of the Cattell Horn Carroll (CHC) theory of intelligence – the most widely-accepted view of intelligence today.

As the table demonstrates, the IDS-2 is currently the only test that measures all components of the CHC model. This was one of the reasons why the IDS-2 was developed; to be able to provide extensive coverage of the information you may want to measure with a child or adolescent.
