OK, so rumour has it that if a school has a bulge class, two or three years down the line there are so many places automatically allocated to siblings that it makes it difficult for anyone else to gain a place. So what does this mean for parents who will be applying for reception starting 2013, as according to my research from Southwark: In 2009/10 we had 3 bulge classes - Crampton (30 places), Goodrich (30) and Lyndhurst (15) In 2010/11 we had 4 bulge classes - Brunswick Park (15), Heber (30), Rye Oak (30) and St Anthony's (15) and two permanent enlargements Lyndhurst (15 - permenant) and Michael Faraday (15- permenant) In 2011/12 there was a whopping 9 bulge classes - Bessemer Grange(30), Alma(30), Camelot(15), Dulwich Village Infants(30), Keyworth(30), St. Anthonys(15), St J and St C(30). These are Southwark schools, but include (highlighted) all the ED schools. I've also heard once a school has bulged, it cannot bulge again for another 3 years - which surely means admissions are going to very tight in 2013? Any thoughts/ further information?
