I think what is more interesting is that with no obvious sign of expansion, although to be fair there has been some internal alterations, a school which consistently and successfully defended over a number of years not to have space for more than their PAN can suddenly (when free to do so) magic up a whole 30 spaces.
It all comes down to money......
I'd be less worried about an extra 30 students in the school than expected for September and be thinking long term when they have 150
more in the school (30 each year over 5 years for every year 7 intake) when my DS was finally in year 11 unless they have clear plans for significant expansion of the buildings to accommodate these numbers. That I would be looking in to if I were thinking of September 2014 entry
