It's the first update to the sex education curriculum in 20 years

All primary and secondary schools are to introduce classes on consent.

The Minister for Education has announced a review of relationships and sexuality education at both levels.

In addition, he wants topics such as safe use of the internet, the effect of social media on relationships and LGBT issues to be included in sexual education classes.

It will be the first update to the sex education curriculum in 20 years and Richard Bruton is expected to announced the changes at the ASTI annual conference today.
