Arizona
The survey was completed during the 2009-2010 school year. The sampling frame consisted of public elementary schools with 10 or more students in 3rd grade. Special schools (e.g. alternative and detention) and schools located in tribal communities or on reservation were excluded from the sampling frame. Within each county, schools were sorted by percent of students eligible for the free/reduced school lunch program (FRL) and a systematic probability proportional to size sampling scheme was used to select 100 schools of which 99 agreed to participate. Twenty-two trained and calibrated dental hygienists completed the screenings using diagnostic criteria comparable to ASTDD’s 1999 Basic Screening Survey. Of the 8566 eligible students, 3150 were screened; for a response rate of 37%. In the state, 48% of public elementary school students participate in the FRL program while 51% of the students in the participating schools were eligible for FRL. The estimates presented are adjusted for the sampling scheme and nonresponse.
