My children's school has an excessive number of newly qualified teachers. The result has been that teaching standards have been poor. Most of the senior teachers have either left or being pushed out by the LEA.
There is no doult that teachers need to start off somewhere, but having too many NQTs makes it harder for more experienced to teachers to mentor them. Many of these NQTs have the potential to become outstanding teachers, but they need a good supportive senior management team.
I feel that a school should have a mixed of both experienced and inexperienced teachers. The number of NQTs should be limited to prehaps 25% of the total number of teachers. Prehaps if the school is hosting PGCE students as well then it should have fewer NQTs.
