The 1998-1999 Total Academic Performance Index (see description) is simply an average across several standardized tests. All of the PACT scores (third through eighth grade with math and language arts subtests in each year), the Exit Exam scores (given in tenth grade with reading, writing and math subtests), and the average SAT scores (math plus verbal) are used in its computation.

The resulting index has a mean of 100 and the eighty-six district scores range from 58.0 to 144.2. A score of 120 would indicate that a district averaged 20 percent higher scores than the state means across all of the standardized tests, or in other words, the district's scores averaged 120 percent of the state means.
