Do watch out for OFSTED ratings though! Check when the last inspection was made. I know several local schools rated outstanding where they have had an almost complete change of staff in the nearly nine years (yes honestly, nine years) since they were inspected. In one school I think the grading is still justified, it is a lovely school, but the others ????
Look instead at the school's published data. This is up to date information that will tell you for example how well FSM children, who often underperform , are doing. Will also give you insight into other areas of the school's performance compared to other schools. Also look at the school's school improvement plan, what are they doing to rectify any weaknesses, if the SIP isn't published then ask why.
Most importantly though, ask around, what reputation does the school have locally for how they cope with special educational needs, do they have a wide ranging curriculum, are music and the arts seen as important, are they involved with the local community, do they have an active and supportive PTA, and is this encouraged by the senior management team.
And also consider how you are going to get to the school, imagine the journey on a cold snowy January evening with a tired five year old, a quick walk along a safe road, or two changes of bus .
