Have a look at www.jags.org.uk for the admissions info: two entries, at 4 or 7 (as of 1 September). At 4, there is an interview session, at 7 an exam and interview. Highly selective. One daughter went to JAPPS (the pre-school), two went to DVIS; the former's class sizes were very small, but facilities not as impressive as DVIS (where the class sizes are larger). I really liked both institutions, so far. JAGS may be ruthlessly selective at 11, however, so we shall see.
