Consent to Participate
The 20 participating schools all volunteered to participate in the study and consented to all study procedures. All participating students obtained positive parent consent to take part in the study survey and provided their assent to take part in the survey. Parent consent forms were available in English and translated into four additional languages as requested by the participating school districts. Consent forms were collected by classroom teachers with support from the study team. Assent forms for the study were collected the day of the baseline survey by trained data collectors. Participants had the opportunity to withdraw assent at any time.
