Notes:

** = Attrition rate is less than zero (0).
. = The necessary data are unavailable to calculate the attrition rate.


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 12th grade enrollment in the end 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.

For a summary of dropout rates over time, see the Longitudinal Attrition Rates in Texas Public High Schools.
