Understanding the reports

Standard age score (SAS)

The standard age score is based on the underlying raw score and enables you to compare your own pupils with a larger, nationally representative sample of pupils of the same age that have taken the test prior to publication.

The national average standardised score is 100, irrespective of the difficulty of the test, and so it is easy to see whether a pupil is above or below the national average.

Stanine (ST)

Stanines (short for ‘standard nines’) are a simplification of the standard age score that divides the SAS into nine broader bands. They show how a student performed on a test in comparison with the national sample, with 9 being the highest score and 1 being the lowest.

The broad nature of stanines minimises the over-interpretation of small, insignificant differences among test scores. Stanines are therefore particularly useful in reporting test information to pupils and to parents, as they are relatively easy to understand and interpret.


Recommendations provided in the individual reports are based on the author’s wide experience of working with dyscalculia. However, local procedures and resources may need to be taken into account in determining an implementation plan. The effectiveness of specialist help depends upon the programme of study fitting the individual circumstances. General prescriptions are likely to be of little use.

There are many products and services that may be effective in providing support to individuals. Intervention may be planned using GL Assessment’s Dyscalculia Guidance handbook.
