How are 11+ and & 7+ prep schools compared?

[bayesian]

In terms of academic progression, how are 7+ only prep schools (or more aptly pre-preps) compared to traditional reputable 11+ prep schools? For example, how do you expect Hampstead Hill School or Wimbledon Common Prep compared to Newton Prep or Falkner House? Considering the earlier exit point, I would reason the 7+ preps stretch the academics faster?

I'm not 100% sure what you're asking so I've made some assumptions and I'm also not familiar with the schools you mention. However given all that - here goes

My understanding is that before 7 years is pre-prep and prep covers 7-13.
Prep schools are usually feeders for specific senior schools which start at 13. Kids who haven't been part of the pre-prep / prep school system (eg state primary) join a prep school at 11 as they can't join senior schools until 13. Very occasionally the senior school will have a separate section for 11-13yr olds, again picking up kids who are transferring from state primaries or from overseas.

The main role of the prep schools is to prep the kids for Common Entrance exams and any specific entrance exams for the senior schools they usually feed through to. So if the senior school is a more high powered academic school, the prep will match that energy.

There are different ways of approaching prep school choice - one of which is to work back from the senior school you're interested in and find out which preps feed through to them. Whilst it's not impossible to get a place at a senior school from a prep which doesn't usually feed through, the child can be at a disadvantage, especially if the senior school sets it's own entrance exam, rather than Common Entrance. I know Common Entrance can be taken at 11 (yr 6) or 13 (yr 8). Taken earlier may suit some children better as the syllabus isn't so broad as the one at 13. So if the child takes CE at 11, they will be offered a place at senior school to start at 13.

All of this applies to boys mostly as most senior school for boys start at 13, whereas for girls they will have intakes at both 11 and 13.

HH goes from 2-11 yrs then check out destination schools
NP goes from 3-13 yrs and again check out their leavers destinations (not available for 2025 yet).
WCP HAD gone from 4-7 but is expanding potentially to secondary level. Again look at destination schools.
FH goes from 4-11 and again the destination schools appears either incomplete or a very tiny cohort.
with WCP (squirrels) expanding they all appear to be in that way traditional to 11+ at the very least.
size; you want a decent cohort of students too small and friendships are an issue, two classes at least as the schools tend to loose students over the years vs gaining students imho you want a graduating class of 40 at least (two classes of 20 for example).
even at 11, the school and children i am familiar with were tutored for 11+ exam tech at the very least.
all the schools mentioned will likely provide a lovely atmosphere and cover both english skills (reading/writing) and math very well.
nothing stopping you from trying 7+ while at these schools (kings takes boys at 7, or what ever girls/co ed school you want to try for at 7).
people say the content is easier at 7 vs 11 and hardest at 13, but it really depends what secondary schools you are aiming for.
personally i suspect all privates any age to 11 or 13 are similar, the difference will be in the cohort (which you have little control of).

pressure and material covered is something you can somewhat extrapolate from the exam results/destination schools (for example how many students applied to city of london vs accepted a place and equally how many students choose a day/boarding school out of the cohort).
distance from home and commute should be easy.
parental stress wise i would avoid excess examinations, not join at 2 finish at 6, need to take 7+ exams/find another school, then 11+ exams for entry at 11 or 13 again finding another school.

I recall a number of previous posts from you looking into similar things. Those they end at 7+ rely on their exit destinations as their marketing tool but many if not all will be tutored. Less pressure in those that end at 11 to be at that level at 7 that others are (I would imagine) but maybe less tutoring too. Although at my daughter’s school which starts at year 3 many were still tutored after entry!

I’d agree with previous poster - less changes make it much less stressful. I’d say 7+ slightly easier depending upon when you’re heading, but also a lot to do with the psychology at 6 years old and very dependent upon how parents approach it. Eg. Let’s go along and have a go at some maths and English and play time v you’ve worked for 2 years for this so let’s not muck this up now (which is what many get even if it’s not outwardly said) x

One question I have as a parent: the terrain seems to be changing again. The 8+ entry route seems to be disappearing and several schools are moving to co-ed.

Where does this leave the traditional boys 13+ entry to senior school? Or will that disappear and everyone simply changes at 11+.
