Every area has its good and bad points Vadi and it depends what you are looking for. Barrhead is one of the more deprived areas of East Renfrewshire and it has a higher rate of crime and anti social behaviour than other areas of ERC. If you'd rather live in a safe, suburban area of East Ren that is not too high priced, you'd be best going for the Woodfarm/Orchard Park area (catchment for St Ninians and Woodfarm), Stamperland (catchment for St Ninians and Williamwood), or certain parts of Newton Mearns (catchment for Mearns Castle or St Ninians). That said, all these areas have less of a sense of community than Barrhead does!
We sold our flat in Pollokshields to buy a house near St Ninians 2 years ago and I am now wanting to move back (or possibly West End) before our daughters start school in Aug 13, despite the local schools there not being so high achieving academically. I teach at a Glasgow secondary and from my own experience, the kids from suppportive, educated families do well in school no matter where they go. We have a high proportion of kids from deprived backgrounds but still have other kids achieving 5 Grade A's every year. The main thing that makes schools like St Ninians 'better' is that they have a catchment of almost exclusively middle class kids. I'm not sure that I'd want my kids to be brought up in such a bubble. I'm also very sure that I don't like staying in the suburbs and would have to admit that this is the main drive behind our next move..
