Figures calculated by IDRA from the Texas Education Agency Fall Membership Survey data. IDRA’s 1996-97 attrition study involved the analysis of enrollment figures for public high school students in the ninth grade during 1993-94 school year and enrollment figures for 12th grade students in 1996-97. This period represents the time span when ninth grade students would be enrolled in school prior to graduation. The enrollment data for special school districts (military schools, state schools, and charter schools) were excluded from the analyses since they are likely to have unstable enrollments and/or lack a tax base to support school programs.

Calculation: Attrition is calculated by (1) dividing the high school enrollment in the end year by the high school enrollment in the base year; (2) multiplying the results from Calculation 1 by the ninth grade enrollment in the base year; (3) subtracting the results from Calculation 2 from the 12th grade enrollment in the year; and (4) dividing the results of Calculation 3 by the result of Calculation 2. The attrition rate results (percentages) were rounded to the nearest whole number.

See also the IDRA’s Attrition Model for a discussion of the theoretical basis for this calculation. See also the Longitudinal Attrition Rates in Texas for a historic view of the dropout rates and comparison between the IDRA Attrition rates and TEA Dropout rates over time.
