I think the whole system is a mess. Where we live, there is a shortage of secondary school places. This has been acknowledged for many years, and the Local Authority has made numerous promises about the building of a new school. After many years, they have agreed to build two new schools and the planning authorities are now dragging their feet to approve the sites. We are still at least four years off.
All local Secondaries are Academies and refuse to increase their intake.
In the meantime, a group of parents have got together with a group of teachers, planned, submitted and successfully been grant the go ahead for a Free School. By next year.
I think the current system is a disaster but, in our case, the Free School has at least been a fall back option.
