Alabama
The survey was conducted during the 2011-2012 and 2012-2013 school years. The sampling frame consisted of all public elementary schools with 20 or more students in 3rd grade. With implicit stratification by dental district and percent of students eligible for the free/reduced price school lunch (FRL) program, a systematic sampling scheme was used to select 63 schools with 3rd grade. If the selected school did not have kindergarten, the appropriate feeder school was also screened. Data is available for all 63 schools. Of the 10,547 children in kindergarten and 3rd grade, 9057 were screened for a response rate of 86%. The survey followed the methods outlined in ASTDD’s Basic Screening Survey. In the state, 60% of elementary schoolchildren are eligible for the FRL program; among participating schools 60% were eligible for FRL. The data were weighted for the sampling scheme and adjusted for nonresponse.
