The PSB started with 4 schools in 2012 with the aim of developing a framework that whilst enabling independence fostered an approach of collaboration with a focus on key skills.
The PSB has grown to 22 schools in 2018, all of which offer in different ways excellence with their provision.
By working together PSB schools are able to offer pupils the pooled expertise of the group whilst remaining distinctive.
