I grew up in a really rough part of Edinburgh where the catchment high school was very grim - super high rates of drinking, teenage pregnancy, truancy, bullying, crime etc, coupled with really low rates of attainment. I wouldn't choose to send my DD to that school, or others which are similar.
In general Clermiston is OK, it's kind of a varied area with some bits being a bit on the rough side but afaik most of it is OK, and it feeds to Royal High which is good.
High school wise, ones I would definitely consider are:
- Balerno - Ratho and Kirknewton are two out of town areas which feed to Balerno and are often cheaper
- Broughton - seems to be becoming increasing well regarded - but when you are looking at property be aware that it has a really mixed catchment, stretching from the New Town through Stockbridge and Inverleith right down through Granton and Drylaw. There's a fair few Edinburgh schools like that!
-Boroughmuir
-Craigmount
-James Gillespies
-Portobello
-Royal High
-Trinity - seems to languish surprisingly far down the league tables for 5+ highers, but is better for fewer and has a good reputation locally. Loses a lot of children to private schools both at the primary school transition and I also know of a few who've gone for S5/6 which I think may have an impact.
There are doubtless other good schools which I'm not familiar with though!
If it would help you could say what you need housing wise, budget and where you need to be able to get to for work and I'm sure we can suggest some places that might not be immediately obvious to a non-local!
