What families in Buckinghamshire need to know
- Two papers of roughly 60 minutes each: one on verbal skills, one combining mathematical and non-verbal skills. The standardised score weights verbal 50%, maths 25% and non-verbal 25%.
- The qualifying score is 121.
- TBGS re-appointed GL on a five-year contract in June 2024, so the provider is settled for this round and several rounds ahead.
