Prospectus looks good and yes there are some contacts who have send children there (and are presumably happy with the school). Looks like a good type of school (indie primary with no linked senior so no pressure to go there) .
Obviously proud of its scholarships and selective places, but what a shame putting "various comprehensives" on the bottom of the destination list.... (kids like to look at lists and say "that's me..").
Have you been to have a look? You will very quickly know if you like the atmosphere, go during a working school day - it will all be there, the way the staff greet each other , the greeting you get, the happiness for parents to see the school warts and all, the kids being trusted to do things eg fetching someone , kids responding well to adults and looking happy and bouncy, a buzz (not a noise, but not quiet either..), does the head hide under the table? -
( - joke for the kids at one school I saw, kids adored her and atmosphere was great- can't say same for her replacement)
My only concern wherever you go (and once you can't do much about) is that leaving at the end of year 4 and doing just years 5 and 6 is not ideal. It will take a child a bit of time to settle in in year 5(hopefully not that long), get in tune with the way they work etc then the entrance exams are at the beginning of year 6...... I have heard heads say that joining private primaries after year 4 can be difficult both for the child and the other kids in the class..
