The Sex Educational Forum is a well-respected organisation. They offer free resources for schools linked to a range of themes including recognising positive relationships, risky behaviours, advice and guidance on SRE and a particularly useful checklist for SRE in schools. They continue to work with the PSHE Association and Brook.
