Hi, the article you refer to above is about the expansion of Bernards Heath, Mandeville and Margaret Wix schools, which was not the solution in the opinion of city centre parents! If you are living in St Michaels it is unlikely you'd want to trek to any of these schools, and it wont directly help the issue with the city centre schools.
However, it is possible that the sibling issue will be less bad in the next few years, but the schools are still notoriously oversubscribed even without the sibling issue.
Like others have said though, so much could change in the (minimum of) 5 years, in primary and secondary. In 5 years Sandringham had gone from a problem school to one of the most popular secondary schools in St Albans.
But it might be helpful to have a guide anyway:
St Michael's school has an intake of only 22 and they mix year groups, so that throughout the school, except in year 6, the classes are mixed. (There are 5 classes at the school rather than 7 like in regular primaries) If you don't attend the local church then you would have to live very near by or be willing to stay on the waiting list after term has started.
The Abbey school - one class per year of 30 places. As above in terms of getting in.
Aboyne Lodge, one class of 30 per year, even without the sibling rule you need to live within 400m or so to stand a chance.
Prae Wood - one class of 30 per year. This year some children right on the estate didn't get in, but occasionally kids from St Michael's have got places.
Bernards Heath and Fleetville are all 3 form intake, so 90 places. Makes them a little easier to get in to. Bernards Heath is undersubscribed, but had considerably more applications this year than last year, so it is likely to become oversubscribed. Not sure how close you have to live to Fleetville school to get a place, but anywhere in the area of Fleetville should be ok.
Currently The Fleetville/Bernards Heath areas are better for Secondary, but people living a mile away from Beaumont and Sandringham didn't get in this year. (whereas that used to be a safe distance)
To be honest, it is probably better to choose an area you like the feel of and wait and see what the school situation is like when you come to it.
Fleetville is a community in itself and has great facilities and buses. Good range of house types and prices too.
St Michael's is really nice for the park (and the waffle house ) quaint houses and from certain spots really nice views.
Bernards Heath you'll prob get more for your money, nearer to Sandringham school, but it doesn't quite have the same character as the other places. (IMO)
Good luck, and welcome in advance to St Albans
