I agree Wax
I went to a "good" school (Bearsden Academy) and got "good" results (6 Highers in S5, all As - Maths, Physics, Chemistry, English, French, Latin) but I would still argue that it wasn't as good a school as the school ds went to (one of those "rubbish"
Glasgow schools)
.
Bearsden Academy only cared about the clever kids (like me
), whereas Shawlands Academy worked to get the best out of all its kids, whether they are academic (like ds) or not - and to ensure that they are rounded individuals, with other interests beyond just academic (in ds' case, his sport) and with an understanding of its varied and multi-cultural demographic.
As a result it gets excellent results (with kids regularly going on to do medicine, law, vet science, PPE, PIR, some going to Oxbridge), well above its expected demographic. But it also works hard to positive destinations for all its young people.
Their young people also (and very importantly) don't have a high drop-out rate when they go to Uni.
I'd assumed when I had ds that I'd move back to East Dunbartonshire (where I was brought up and my parents still lived) or East Ren. I then did my homework and realised that I was not only in the catchment of an excellent primary, but that we didn't even need to move for secondary
Just as well as we love our home and before we found it, we'd spent two years looking fruitlessly in East Dunbartonshire and Stirlingshire, before finding it on the first night of looking on the Southside 
From what I understand, Hyndland has a very similar ethos (and results) to Shawlands
