demand for private secondary schools outstrips supply.
Demand for State secondary schools that are rated outstanding outstrip supply in London, as do selective and semi selective outstanding state schools in London, but not really private secondary schools. There are so many shapes and sizes of school, everyone finds one in the end, it may not be what you dreamed about, but they'll find a good fit for their DC in the end.
The fact you need around 250K to educate your daughter from age 11 to 18 at London private schools reduces the applicant pool massively compared to top London top state schools, less than half for St Pauls Girls compared to Tiffin. Secondly high exam entrance pass mark for the elite schools, means many try, few enter. On another thread a poster typed 1400 applicants for 100 places at a top London private secondary school, as if 1400 applicants are all passing at 85% the exam entrance. And lastly parents like me who have been shelling out fees since their children were 2 in expensive Preps won’t be applying for just one private secondary school, we'll be applying for 5, 6, 7 even 8 schools, but we only really want 'the one' that her friend from Prep has applied to, is a short walk from home and has a great music department compared to school 2, 3, 4, 5, and 6.
So do not fear the 11+, keep your DD where she is and spend the money on an excellent tutor to train her mind and prep for 11+, take mock exams and use those to judge where to apply, a good tutor will help with this in the absence of a Prep head.
It’s not rocket science, if the secondary school you're after is on this list, it will have lots of kids applying, but many of them won’t be smart enough or the parents will just be hedging. A girl aiming for St Pauls will only apply to Francis Holland as a back-up for example, just as a girl who’s Francis Holland level, might apply to St Pauls as an ‘aspirational’ choice ( read no hope).

Private secondary schools won’t assess your DD the same as the ones coming from the current prime ministers’ daughters prep school, so don't think of the Prep school kids having an upper hand. These schools are far more nuanced, just make sure she aces the entrance exam and gets some interview practice with a family friend, do your research, save your cash.
