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.

Idaho

The survey was conducted during the 2012-2013 school year. The sampling frame consisted of all non-virtual public elementary schools with 20 or more third grade children. The sampling frame was stratified by Idaho's seven health districts. A systematic probability proportional to size sampling scheme was used to select 70 schools. Of the 5507 children invited to participate, 4737 were screened for a response rate of 86%. The survey followed the methods outlined in ASTDD's Basic Screening Survey. The data were weighted for the sampling scheme and adjusted for nonresponse.

Oklahoma

The survey was completed during the 2012-2013 school year. The sampling frame consisted of all public and private elementary schools with 5 or more students in 3rd grade. The sampling frame was stratified by the 6 regions in the state with schools randomly selected within each region. Thirty-six schools were selected of which 33 agreed to participate. Two dentists completed the screenings using diagnostic criteria comparable to ASTDD's 1999 Basic Screening Survey. Of the1917 eligible students in 3rd grade, 788 were screened; for a response rate of 41%. In the state, 67% of public elementary school students participate in the FRL program; 69% of the students in the participating schools were eligible for FRL.

Rhode Island

The survey was completed during the 2012-2013 school year. All 39 Head Start sites in RI were invited to participate of which 29 agreed. Of the 2466 children enrolled in Head Start, 809 were screened for an overall response rate of 33%. Seventeen trained dentists completed the screenings using diagnostic criteria comparable to ASTDD's 1999 Basic Screening Survey. The estimates presented are adjusted for nonresponse.

South Carolina

The survey was conducted during the 2012-2013 school year. The sampling frame consisted of all public elementary schools with 15 or more students in 3rd grade. The sampling frame was stratified by region then ordered by percent of students participating in the free/reduced price school lunch (FRL) program. A systematic sampling scheme was used to select 68 schools with 3rd grade students. Of these 5 did not have kindergarten children so the 5 feeder schools with kindergarten children were added to the sample. In addition, 2 volunteer schools were also screened. Data was obtained from all of the sampling intervals. Of the 12,894 children invited to participate, 6433 were screened for a response rate of 50%. The survey followed the methods outlined in ASTDD's Basic Screening Survey. In the state, 58% of elementary schoolchildren are eligible for the FRL program; among participating schools 57% were eligible for FRL. The data were weighted for the sampling scheme and adjusted for nonresponse.

Texas
