The Priory is an academy school and made up of four local schools, The Priory Witham, The Priory City and The Priory LSST and an infant school. I suspect that you are looking at The Priory LSST. My understanding it is non-selective, however there are a certain amount of places for yr 7 children who sit an internal exam. They also run masterclasses for children who will be applying. It has fantastic facilities and a very good ethos.
