Curriculum Development 
STDS
High School FLASH is a comprehensive sexual health education curriculum developed and maintained by a county public health department. It is a public health strategy for classroom settings, with the specific behavior change goals of preventing unintended pregnancy, preventing STDs, and preventing the perpetration of sexual violence. FLASH is developed for use in public schools and as such is designed to be relevant and accessible to young people of all sexual orientations, genders, and family configurations. The Human Rights Campaign (HRC) states that LGBTQ inclusive sexual health education lessons are those that “help youth understand gender identity and sexual orientation with age-appropriate and medically accurate information; incorporate positive examples of LGBTQ individuals, romantic relationships and families; emphasize the need for protection during sex for people of all identities; and dispel common myths and stereotypes about behavior and identity” (HRC, Inclusive content was created for use in all lessons, as well as creation of a lesson focusing specifically on the concepts of sexual orientation and gender identity. Messaging from all lessons was tested with a diverse group of young people, in which LGBTQ youth were purposefully overrepresented. Messages were adjusted according to feedback and re-tested until acceptability was reached. The lessons were subsequently piloted in public school classrooms to gauge understandability and ease of implementation. If revisions of any magnitude were required, they were again tested with groups of young people before being piloted once more. This process helped ensure that young people perceived the content to be affirming and relevant, while also ensuring it was understandable and promoted the behavioral outcomes of FLASH. Additionally, several strategies were tailored during the development of High School FLASH to create a curriculum that would reduce homophobia and transphobia (HRC,
