100% of Secondary schools in my town will be Academies from 1st September. When DD started there 3 years ago, I chose the school partly BECAUSE it wasn't an Academy. Now for her final, most important two years of education, it will be. Choice? HA!
Also 5/7 of the local Secondaries have formed an 'Academy Consortium', run in the same way, with the same hiring terms for new staff, the same admissions criteria etc.
All of which means that there is NO element of choice in whether your child attends an Academy.
My DS's primary is also converting to Academy status on 1st September. I have no choice but to continue to send my two DS's there, as there is an extreme shortage of local primary places for DS2, already in a bulge class. He has been on waiting lists for 6 other local schools for 4 years now, and his highest position on a waiting list is 20th, one school he is 35th on the waiting list.
So no, for lots of people, there is no choice whatsoever about sending their DC's to an Academy.
