There have been loads of threads in the past about the 50% cap on faith-based admissions, which has applied to all the new faith academies and free schools established since 2010. If you're not familiar with it then there's a good Wikipedia article here which gives a lot of background: en.wikipedia.org/wiki/The_50%25_Rule
Theresa May's manifesto said that she would ignore the responses to the Schools That Work for Everyone consultation and remove the cap, but it's all gone very quiet since she was elected with a hung parliament, and the main driving force behind it (Nick Timothy) is no longer her chief advisor.
An announcement is long overdue. A cross-party group of MPs has now started an Early Day Motion (which is a sort of petition for MPs) to say the 50% Rule should be kept. MPs need to be prodded to sign EDMs by their constituents, so if you feel strongly on this, now is a good time to write to them. If you don't have time to write your own letter then the Accord Coalition (campaign group) has made it easy by setting up a template letter: accordcoalition.org.uk/2017/11/10/mps-urge-government-not-to-jettison-anti-discrimination-cap-at-faith-schools/.
It's worth adding that unlike the Grammar School debate, the removal of this cap doesn't need a vote in the house of commons or any change in legislation. The Government can just go ahead and do it if they want to. They just need to change the Admissions Code and the template funding agreements for new faith schools.
It's going to be interesting to see how they proceed, because there is solid evidence that the cap is doing the job it was intended to do, and is popular with the vast majority parents.
I know many people out there think the Government should go further and ban faith-based admissions altogether, but if even this small and unprecedented step in the right direction can't survive then there's little hope for more radical reforms.
