The Basic Number Screening Test is a quick, reliable assessment focusing on children's understanding of number and number operations. It assesses National Curriculum teaching from Years 1 to 5, making the test suitable for use throughout Key Stage 2. The test is delivered orally so assesses pupils' numeracy skills, rather than their reading ability, making it ideal for use with poor readers. It can also be used with older, less able pupils at Key Stage 3. Quick to give and easy to mark, with parallel forms A and B to enable re-testing to assess progress, the test takes about 30 minutes or less to administer to class groups or individual pupils. This new edition has been re-standardised on over 8000 pupils nationally. It now provides standardised scores and - National Curriculum levels as well as Number Ages. The test content is unchanged, giving continuity for current users.

Norms are provided as standardised scores for ages 6:0 to 12:3, and as Number Ages 5 to 12:8. Across this range, an informal 'special needs indicator' helps pinpoint those children who are likely to require some degree of learning support. The test is recommended by Catch Up Numeracy.
