We chose a small village school some 2.5 miles away, because DD was more than ready for school at 4.5, when the village school would take her, but the local one wouldn't take her until she was 5.25.
A large housing estate was built next door to the school about 5 years later & the school rapidly increased from 3 classes (age 4-11) to 8, within 2 years. Children were joining the school every week & the education of everyone was being disrupted.
We'd expected DD to go to grammar school, but we were told she didn't have the right attitude! She passed the 11+ but wasn't allowed a place & the Head fought us all the way. She got an Assisted Place at a private secondary school, & at the same time their junior school took DS2 into Y3.
This school has a high proportion of Hong Kong Chinese students & students from Russia & Africa. It also has a lot of Forces children. At no time did either of mine feel they were "better" than anyone else, especially as their 2 brothers were still at their old school.
The school gave them both confidence and wonderful manners. They were able to go in early & leave late, to accomodate our working day. My DD was very much "younger" throughout her time there than her peers in state schools.
Most of the parents were "ordinary" people in normal jobs who had gone without cars & holidays to pay for their children's education. What makes me really mad is these people who have new cars & expensive holidays then say that private schools should share their facilities.. even on an Assisted Place we struggled, and all our money went in fees. I don't see anyone paying for our holidays or letting us share their car.
DD did her GCSEs then moved to a state grammar for A levels. She finds the state system "appalling". DS went to state grammar after passing the 11+.
DS1 meanwhile is at the local High school & is very happy there. The school has home school contracts (as do both grammars) & is very strict on discipline & uniform. 10 years ago it was a sink school. Now it is over subscribed.
When DS1 left primary we also moved DS3. We drive him 22 miles to another state primary. It has classes of 34 but it is a good school & he has done well there. We moved him when we found that he had spent a WHOLE TERM in Y2 sat outside the Heads office for disruption, and we had NOT BEEN TOLD! He had also had 2 years with a Down's boy in his class who had no speech & a mental age of less than 2. ALL the teacher's time and energy was spent "containing" this child. The rest were left to their own devices. Integration is fine up to a point but when a child is so severely disabled that it affects everyone else then he is in the wrong place. We tried every school in town & all said we were not in their catchment. We had no option but to try another town.
