yes it is bad, my husband is assistant head in another primary school in Redbridge and it's the talk of the town. They will be under special measures. When I moved here 6 years ago, Snaresbrook was the school where all parents wanted to send their children. It was a good school with an excellent headteacher. The headteacher changed a few years ago and it's been downhill since then. He has left when the latest ofsted report came out and there will be experienced temporary headteachers to try and turn the school around. Things change very quickly and hopefully the school will improve within a year or two. They basically failed in all areas covered by ofsted, 4 is "A school that requires special measures is one where the school is failing to give its pupils an acceptable standard of education and the school?s leaders, managers or governors have not demonstrated that they have the capacity to secure the necessary improvement in the school. This school will receive regular monitoring by Ofsted inspectors."

The full inspection report is available here: www.ofsted.gov.uk/inspection-reports/find-inspection-report/provider/ELS/102832
But things do change quicky after a poor inspection so it might play in your favour, ie the school will not be full but will improve.
When you come to apply, you should put Nightingale first, then Snaresbrook, then maybe Churchfields in South woodford, an excellent primary school a bit further out. Chances are, you will be assigned Snaresbrook but you can then put your child's name down on the waiting list for other schools (even for Wanstead Church School if you don't mind CoE). If you are not happy with Snaresbrook then you can take a place in another school if/when they become available.
