The survey was conducted during the 2001–2002 school year. This study was designed to provide a representative sample of Oregon public school children in grades 1 to 3. The sample design for this survey used a probability-proportional-to-size (PPS) selection of schools from Oregon’s public school system. Schools were selected from a list generated from Oregon Department of Education data. Implicit stratification on health region and percent of children in the school eligible for the state free/reduced lunch program was used for the school selections. Children in 1st, 2nd and 3rd grades were screened. The diagnostic criteria were comparable to ASTDD’s 1999 Basic Screening Survey. In the state, 41% of students were eligible for the free/reduced lunch program (FRL); 44% of the students participating in the survey were eligible for FRL. The response rate was 47% for 1st grade, 37% for 2nd, and 39% for 3rd. The estimates were adjusted for nonresponse. The data were weighted to account for the survey design.
