How to Read the Data
When calculating the achievement gaps for each year, I used the Washington Assessment of Student Learning passing percentage number for White students and subtracted the passing percentage number for African American and Hispanic students, which gave me the difference (achievement gap percentage).
Example:
Franklin Pierce School District
7th Grade Math
White passing percentage
1997-98 11.6%
2004-05 47.6%
African American passing percentage
1997-98 2.5%
2004-05 20.0%
11.6% - 2.5% = 9.1% Achievement Gap 1998
47.6% - 20.0% = 27.6% Achievement Gap 2005
