Special Note(s)

In each grade, students are randomly assigned to complete questionnaires with a subset of topical questions in addition to a set of core questions on demographics and drug use. Some topical questions collect data on diet and physical activity, but these questions vary by survey year.


Sample Design

Cross-sectional survey.

Multi-stage random sampling is performed each year to obtain a nationally representative sample of students in each targeted grade. Learn more about the sampling design.

Sample Size

Approximately 50,000 8th, 10th, and 12th grade students in approximately 400 public and private middle schools and high schools are surveyed each year.

Special Note(s)

Within each school, up to 350 students may be included. In schools with fewer students, the usual procedure is to include all of them in the data collection. In larger schools, a subset of students is selected either by randomly sampling classrooms or by some other random method that is judged to be unbiased. Sampling weights are used to correct for unequal probabilities of selection that occurred at any stage of sampling.
