Description:


Raven's Progressive Matrices and Vocabulary Scales enjoy a long and famous history in the assessment of general cognitive abilities in children.

The Progressive Matrices usefully provide an assessment of non-verbal ability, an important feature for a diverse population, and the Vocabulary Scales provide scores in the verbal domain.

This important instrument has now been restandardised for the UK population.

In this standardisation study 640 children aged between four and 11 years were administered the Coloured Progressive Matrices (CPM) and the Crichton Vocabulary Scale (CVS) and 960 children aged between seven and 18 years received the Standard Progressive Matrices - Plus version (SPM-Plus) and Mill Hill Vocabulary Scale (MHV).


The data was collected in groups for the SPM+ and MHV and comparison studies against individual administration were completed. Equating studies on other forms of the progressive matrices and vocabulary scales (e.g. SPM-Classic, CPM-parallel) were also carried out.

This standardisation represents the most significant development for the children's version of the Raven's progressive matrices and Vocabulary Scales since the 1979 & 1982 standardisations with children aged from five to 16 years.

Along with this standardisation, Pearson Assessment has completed an extensive redesign of the product, simplifying and updating materials. This makes the test more attractive and easier to use.

India Norms:

Norms were collected for the Indian population between the ages of 8 and 21 years. Two normative studies were conducted in India, for which norms are available: the Delhi Study with norms for ages 9 to 21 years and the Pune Study with norms for ages 8 to 18 years, respectively. The normative data obtained was published in 2002 as part of a project carried out by C.G. Despande and J.M. Ojha.

NB There is an overlap in the normative UK data for the CPM/CVS kit and SPM+/MHV kit for children aged between 7 to 11 years. It is advised that the examiner uses their professional judgement as to which would be the most appropriate test for their use when they are seeing children within this age range. CPM/CVS is an individually administered test and has easier items than SPM+/MHV. The SPM+/MHV and the SPM can be administered individually and in groups.

The following kits are available:

·      Raven's - Educational CPM/CVS complete kit with UK Norms

o  Individually administered test for children aged 4 to 11 years.

·      Raven's - Educational SPM+/MHV complete kit with UK norms
