It is more than two decades since academies were first introduced to the English education system, and around half of all state-funded pupils now attend one. Yet, in its new report 20 Years of Muddling Through, think-tank EDSK argues not only that the language around academisation has become too politicised, but that the system itself is unsustainable.

Here, Tom Richmond, EDSK’s founder and director, speaks to NAHT assistant general secretary James Bowen about why he thinks it’s time we leave behind the political baggage and build a coherent, collaborative and transparent system based on the principle of ‘one set of rules for everyone’, allowing teachers and leaders to devote their energy to improving teaching and learning.
