Theresa May has set out plans for a new generation of selective grammar schools, as part of a drive to make Britain "the great meritocracy of the world".
The Prime Minister was accused of "putting the clock back" by chief schools inspector Sir Michael Wilshaw, who warned that a return to grammars would halt momentum towards better results in the state system.
Sam Freedman, executive director of programmes for charity Teach First, has said grammar schools will not support those who would "benefit most from a good education".
Reacting to Theresa May's announcementthat selective schools will be expanded, he said: "Even with quotas, by their nature grammar schools will only ever support a small proportion of children and not those who would benefit most from a good education.
"We already know the best ways to use education to support social mobility and we need to focus on making sure all pupils get an outstanding education, leaving school ready for life in a global economy."
The prime minister's big challenge now is to prove how selective schools (Theresa-style) will not cream off the brightest and best.
The prime minister has unveiled plans for "ambitious" education reforms which include new grammar schools, here's what we know so far.
The PM believes grammar schools allow the best to succeed - but the question is whether they raise standards for all.
