Longitudinal high school completion data are provided for the class of 2008 by ethnicity, gender, socioeconomic status, program participation (bilingual or English as a second language, career and technical education, gifted and talented, special education, and Title I) and other student characteristics (at-risk, immigrant, limited English proficient, and migrant). Some data are masked to comply with federal regulations concerning student privacy, the Family Educational Rights and Privacy Act (FERPA).

The completion rate is the percentage of students from a class of beginning ninth graders who complete their high school education by their anticipated graduation date. Completion may be defined as graduating, continuing in high school in the fall after graduation was expected, or receiving a General Educational Development (GED) certificate. The completion I rate consists of students who have graduated or continued in high school. The completion II rate consists of students who have graduated, continued in high school, or received GED certificates. Students who enter the Texas public school system over the years are added to the class, and students who leave the system for reasons other than graduating, receiving a GED certificate, or dropping out, or who could not be tracked from year to year, are subtracted. A longitudinal dropout rate is the percentage of students from the same class who drop out before completing their high school education. Dropouts are counted according to the definitions in place the years they drop out. The definition changed in 2005-06. Completion rates for classes in which the national dropout definition is being phased in (i.e., classes of 2006, 2007, 2008, and 2009) are not comparable to completion rates for the class of 2005 and prior classes, nor to each other.

As an example, the longitudinal rate for graduates is calculated by dividing the number of students who graduated by the number of students in the class:
