The government has issued advice to local authorities on dealing with protests outside schools over LGBT-inclusive teaching.
The 21-page document, seen by the BBC, lays out how councils should support teachers to minimise disruption.
It comes after continued protests outside schools in Birmingham against the teaching of LGBT relationships.
The Department for Education (DfE) said it was working to ensure authorities had information to support schools.
The No Outsiders equality programme, which encourages children to accept differences in religions, families and relationships, was suspended in March amid angry protests at the gates of Parkfield Community School in Birmingham.
Protesters stated the subject matter contradicted the Islamic faith and that primary-age children were too young to be aware of same-sex relationships.
