A coalition of religious leaders are calling for a "rebalancing" of faith schools, including making sure parents do not use religion to try to gain a place at a popular school.
The Accord Coalition says it is also concerned that some faith schools are "blinkering children's educational experiences".
We write as religious leaders from a broad spectrum of faith groups who are united in our concern over the way faith schools currently operate - both because of their impact on the children that attend them, and their effect on society at large,"
Among the measures in their six-point manifesto is making sure state-funded schools are only allowed to select 50% of pupils on the basis of their religion.
Among the other points is ensuring teachers are not employed on the basis of their faith and doing away with compulsory collective worship in schools.
