Education secretary Michael Gove agrees with Professor Alison Wolf that “perverse incentives created by performance measures ... have resulted in large amounts of sub-standard education” (“Purge of Ofqual and the ‘useless qualifications’ in ministers’ sights”, 4 March). And he believes that “performance tables incentivise schools to offer these inadequate qualifications”.

Why, then, does he not abolish league tables instead of seeking to replicate the previous administration’s mistakes by replacing one set of “perverse incentives” with another?
