 At the start of each semester, the targeted sections of 9th grade health class will be randomly assigned into one of three research groups: 1 a group that receives the full, 12-lesson RS curriculum, 2 a group that receives a summary 8-lesson version of the RS curriculum and four lessons on career planning and job readiness, or 3 a control group that receives lessons on career planning and job readiness without any lessons from the RS curriculum.
