Inform

Every grant the Foundation makes has to serve at least one of these. They were set when the Trust Fund was established in 1980, and they are the framework the Trustees assess applications against.
Inform LGBTIQA+ people about community-based groups and organisations.

Advocate for social and legal equality for LGBTIQA+ people.

You do not need to hit all six. Point at the ones your project genuinely serves and explain how — that is more useful to the Trustees than a list.
The application guide goes through this, and the rest of the form, field by field.
