What schools say about BNST
I would really recommend it. From being able to identify learning gaps early on... to being able to easily get clear information about how the children are doing, I think that this is a well thought out, really useful diagnostic tool for schools.
Catrin Tingle Extended Leadership Team Member, Nine Acres Primary SchoolBNST is very useful as a baseline test for interventions and checking the effectiveness of the interventions as there are two strands to the test. It is also useful to identify areas of strengths and weaknesses in children. The test is easy and quick to administer – it can be done in groups/whole classes which makes it time efficient. It is also easy to make and results can be seen in standardised scores or maths age.

Check out SNAP Maths
If BNST identifies learners who are significantly behind in their maths learning, SNAP Maths can help you to identify other barriers that could be impacting their maths learning including specific maths learning difficulties/dyscalculia and maths anxiety.
