In the experimental arm, the Re:MIX curriculum was implemented. The Re:MIX curriculum is a comprehensive teen pregnancy prevention consisting of ten hour-long sessions, delivered approximately once per week. The Re:MIX curriculum is taught by a professional health educator, partnered with a young parent educator who is a young parent (aged 18-25).

In the comparison arm, teachers were given the option of implementing the Healthy Youth, Healthy You curriculum (focusing on nutrition, mental health, and fitness) or proceed with "business as usual" (no curriculum).

Re:MIX is a comprehensive in-school health curriculum and teen pregnancy prevention program for adolescents covering a broad range of topics related to sexual health and youth development, including healthy relationships, communication, gender, consent, reproductive anatomy, contraception, sexual decision making, clinics, parenthood, and life planning. Re:MIX also aims to connect students and young parent educators with community resources and service linkages. The Re:MIX curriculum teaches mixed-gender groups of students in grades 8 to 10 to delay sex and use protection if they have sex. A co-facilitation team of young parent educators delivered the information with professional health educators using non-traditional approaches, such as game-based tools, technology, and storytelling. Youth received roughly nine hours and 10 minutes of group sessions during the school day over one semester (55 minutes per week for 10 weeks).
