The federal government has unveiled changes it wants made to a controversial anti-bullying program in schools.

They include limiting the program to secondary schools only.

An independent review of the Safe Schools program found that a number of the resources had lessons and content not necessarily appropriate for all children, Education Minister Simon Birmingham said in Canberra on Friday.

"Every student has a right to feel safe at school. Tolerance should be taught in our schools and homophobia should be no more accepted than racism," he said.
