Northern Ireland's post-primary schools have been given guidance on how to deliver classes on sex education.
They must teach about access to abortion and prevention of early pregnancy, under new regulations introduced last year.
The Department of Education (DoE) held a public consultation which would influence under what circumstances a pupil might be removed.
A total of 13,461 responses were received with over 25,000 comments.
Before the new policy, each school in Northern Ireland has been required to teach relationships and sex education (RSE) but the curriculum has been a matter for each school to decide, based on their school ethos.
That approach has previously been criticised by some experts, who have said it leads to "different and inconsistent learning experiences" for pupils.
However, the move by NI Secretary Chris Heaton-Harris means post-primaries would have to teach pupils about issues such as how to prevent a pregnancy, the legal right to an abortion in Northern Ireland and how relevant services may be accessed.
