Teachers of students as young as 5 will soon have access to new sexuality education guidelines addressing issues such as identity and relationships.
The guidelines commissioned by Family Planning are designed to help teachers of students in Years 1 to 4, and will cover body parts and differences between boys and girls - but not sex.
Co-author and Canterbury University education lecturer Tracy Clelland said the guidelines focused on identity, self-worth, friendships, relationships, being confident in yourself and expressing emotions.
Speaking from the Family Planning conference in Wellington yesterday, Ms Clelland said research towards the guidelines had been based on international evidence.
By Year 4, when children were 8, they were allowed to watch MTV and the Miley Cyrus "twerking" incident, she said. "And what school allows them to do is to actually deconstruct this - let's think about this. I think that's really important. And a lot of children are unsupervised as we know,' Ms Clelland said.
