I am aware of so many people in your situation, it is terrible.
We live on Berber Rd, and luckily have a place at Belleville this year. However, the houses either side of us are rented, and each year are generally occupied by families wanting to get their children into Belleville. As soon as they secure a place, they move or return to their homes elsewhere, outside the catchment area.
It infuriates me. Belleville and Honeywell are meant to be schools for children who's families genuinely reside locally. The schools or Council, or both, need to find a way to stop people manipulating the entrance system.
We are in the same position as many of you. We have written to the council , our MP and the school.
The council basically washed their hands of the whole renting thing saying here was nothing they can do as it was not economical to check all applications thoroughly. The MP was sympathetic she is a governor at honeywell and said governors there have rented to get a place. At both schools it is the governors that make the admissions policy as far as I understand. So there is no desire to change the system.
I think we all need to write to everybody, the council, the school and the MP. The more fuss is made maybe someone will do something about it.
I also think if you know of people who are renting to get a place you should tell the council. We told them of people we know who have done this and are waiting it see if they lose their place. The council claims if you obtain a place fraudulently that it will be removed.
