I think a little perspective here is needed, I attended RPS, PGS and SEJS and know people from all of the schools in cheltenham, including many of the people who were involved in the suicides and bullying incidents.
Firstly, the spate of suicides were confined to the senior schools, and were not limited to SES, but occurred in schools across Cheltenham, that, tragically is how these things happen. SES did have a separate bullying problem that the previous headmaster failed to deal with appropriately, but many lessons have been learned since then
St Ed's has had problems in the past, certainly up until a few years ago, but a new headmistress, a serious attitude shift in terms of pastoral care and academic focus have given it a new lease of life.
Additionally SES and SEJS have gorgeous grounds, and fantastic facilities, (admittedly so do DC and CC, but these are located in the town centre, or next to main roads). SES is a great school, and I'd advise anyone to go and take a look before pre-judging.
