We have just done this with my daughters 4+ place. The place we gave up was at a very academic, selective school. I'm hoping to hear from others who did this and were pleased with the outcome. Our reasons were mainly financial, though not entirely- we could have afforded the fees but we would have had less security in terms of savings and a lot less money month to month. We were also offered a place at a sought after state primary which is rated outstanding and has been, consistently, for years.
However, I am in turmoil about the decision. My husband was never behind the private school choice- was worried about the cost of it and didn't really agree with it on principle either. He agreed to it because we never expected to get the state school we were offered, and because he knew how much I wanted the private school. I worked for months with my daughter to get her in. We've agreed that we will sit her again at 7+ when out financial situation will be different. I know 7 plus is hard.
Please be kind. This has been an incredibly tough week and I'm hoping some of you can reassure me that we've done the right thing.
