Matrix Calculation

Some secondary programs use a matrix to qualify students. Students who are qualified are entered in a lottery to determine who is offered a seat. This year, all schools that use a matrix will be using the same matrix.  

The matrix formulas are as follows:

• Method 1 (traditional HISD formula): Uses student 2022 STAAR scores combined with end-of-year grades, or core average, to calculate a combined matrix score.
• Method 2 (expanded formula): Uses 2022 end-of-year grades ONLY to calculate a core average matrix score. 

Only the highest score will be used for your child’s application.
