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.
Labour leader Jeremy Corbyn has criticised the Government's plans to introduce new selective schools.
Under plans unveiled by the prime minister, children will sit new selection tests aimed at assessing their "true potential", Theresa May said.
"I want good education for every child. Selectivity at 11 divides communities, divides children and ends up giving a good chance to a minority and less chance to the majority."
"I don't think that's a very sensible way forward for our country," he added.
Mrs May said schools will be urged to recruit at 14 and 16 as well as 11 to avoid the danger of children being written off as non-academic at the start of their secondary careers.
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.
