The government is concerned that the quality of sex education is patchy, and that poor services can lead to health problems and unwanted teenage pregnancies.
It has set up a steering group to find ways to address this in primary and secondary schools.
The group will be jointly chaired by schools minister Jim Knight, Newcastle College principal Jackie Fisher, and UK Youth Parliament member Joshua Taggart.
It includes representatives from across the sex education field, including teachers, nurses, charities, and young people.
Knight said: "We know that SRE is good in most schools but we know from talking to young people that in some schools SRE teaching is not up to scratch. This is not acceptable.
"I want to look at what the best schools are doing and make sure every school follows their lead."
As well as looking at best practice in providing education in schools the review will also look at the role establishments can play in referring young people to external services.
Beverley Hughes, the children's minister, said: "Consistent delivery of SRE across England will also help tackle teenage pregnancy in those areas that are still struggling."
