The study is an individual randomized controlled trial in which eligible, consenting ninth grade participants are randomly assigned by the evaluator to intervention (PGC) or control (business as usual) groups at a 1:1 ratio. Primary outcomes will be assessed using questionnaire data gathered at three time points: baseline, occurring during the fall of participants' 9th grade year (prior to the provision of any PGC programming), and follow-up during the fall of their 10th and 11th grade years. Primary outcomes of interest include sexual initiation, frequency of any type of sex, and number of sexual partners.
