A NATIONALLY funded program designed to wipe out homophobia in schools and assist same-sex and gender diverse students has been accused of having a "sexuality agenda".

The Safe Schools Coalition Australia program received $8 million from federal governments to help create more inclusive school communities.

It will be introduced in participating Tasmanian schools in the coming months, with three Northern schools already signed up.

The Australian Christian Lobby, backed by the Anglican and Catholic churches in Tasmania, is urging school communities to get informed before accepting the coalition's anti-bullying program.

It sent letters to public school principals and school associations.

Safe Schools Coalition Australia program director Sally Richardson said she was concerned the campaign and its outdated views would make some schools nervous about signing up for the nationally supported program.

"That would be a terrible shame because the people who are most harmed by it are the young persons in schools," Ms Richardson said.

"I really hope they see past this negative message and look at the welfare of their students.

"These views are sensational and above all, the people writing this material have lost touch with the fact that the health and wellbeing of a young person is the most important thing."

ACL state director Mark Brown said schools should be made aware of sexualised content in the safe schools program before any rejection or acceptance of the program.

Catholic Archbishop Julian Porteous said SSCA was using the issue of bullying as a means to impose a particular sexuality agenda on schools.

"Parents have the ultimate responsibility for sexuality education for their children and this sensitive issue needs to be carefully discussed by parents with schools and not simply imposed through an anti-bullying program," he said.

"The pastoral approach of the church in this area is not to deal with young people in terms of labels, whether this be lesbian or gay, rather, we see each individual as a human person created in the image and likeness of God."
