Our local secondary school recently converted to academy status. The school has been consistently oversubscribed for many years. After consultation, the governors decided to change the school's admissions policy. The key change was to give higher priority to children living within a specific postcode area (a controversial decision as it will result in many cases where a child living further away gets priority over a child living nearer the school but in a different postcode area). However, after the special needs/children in care-related priorities the changed admissions policy still gives the highest priority of all to siblings (regardless of address). The first year for which the intake will be governed by the changed policy is the year starting Year 7 in September 2014. I have a friend whose son is due to start secondary school in September 2015. His older brother is already at the school, so provided high priority continues to be given to siblings he should get a place. However under the new rules which prioritise a particular postcode, he would be unlikely to get a place without sibling priority as he does not live in the priority postcode area. (NB The family has not moved house. Older brother got his place based on current address under the old admissions policy.)
My friend has heard a suggestion that the policy might change again for the September 2015 intake so that sibling policy is removed/only applies to siblings in the priority postcode area. I was surprised at this as I thought that an academy was not allowed to change its admissions policy for two consecutive years and that therefore, whatever might happen in the future, the admissions policy for the September 2015 intake would be bound to be the same as for the September 2014 intake.
Would the school be allowed to alter its admissions policy for the September 2015 intake?
