Four-year longitudinal graduation, completion, and dropout data are provided for the class of 2009 by ethnicity, gender, economic 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).

A four-year longitudinal graduation rate is the percentage of students from a class of beginning ninth graders who graduate by their anticipated graduation date, or within four years of beginning ninth grade. A four-year longitudinal completion rate is the percentage of students from the same class 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 four-year 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. Longitudinal rates for classes in which the national dropout definition was phased in or fully incorporated (i.e., classes of 2006, 2007, 2008, and 2009) are not comparable from one class to another, nor are they comparable to rates for prior classes.

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