Delaware
The survey was conducted during the 2012-2013 school year. The sampling frame consisted of all public elementary schools with 10 or more students in 3rd grade. With stratification by county and implicit stratification by percent of students eligible for the free/reduced price school lunch (FRL) program, a systematic sampling scheme was used to select 23 schools with 3rd grade. Data is available for all 23 schools. Of the 2,189 children in 3rd grade, 828 participated for a response rate of 38%. The survey followed the methods outlined in ASTDD’s Basic Screening Survey. In the state, 52% of elementary schoolchildren are eligible for the FRL program; among participating children 41% were eligible for FRL. The data were weighted for the sampling scheme and adjusted for nonresponse.
