RAN – Digits

This test measures naming speed of numeric items, that is, of visually presented items that require number knowledge.  More specifically, this test measures the ability to quickly and fluently produce verbal labels for highly familiar single digits.

Age range

Because it is an alphanumeric test, this test is appropriate for Year 1 and 2 (and older) children.  It is not appropriate for most Reception Year pupils.

Scoring: speed, errors

Speed: Naming speed is obtained by averaging the number of seconds taken to name the full set of digits across two trials.

Errors: The error rate is obtained by averaging the number of incorrectly named and skipped digits across two trials. Note, error rates are only considered qualitatively as these are usually very low.


Current English norms are available for children in Years 1 and 2.

Norms tables will be added soon.
