"The solution is to make all the schools as desirable as the most popular ones ..." easier said than done, I think! The removal of the sibling priority would make the whole process fairer (and yes, in an area with many single sex schools it's an oddity in itself) and would discourage the adroit moving into and out of rental properties that we all know goes on. Also, Kingsdale should not operate a lottery system in a vacuum. Either all schools in a borough do it or none do. But I and many other parents were saying all this back in 2011 - so good luck with your petition Oscar 38!
