State test scores show a disparity between minority groups in the South Sound. Below is a tool that illustrates the percentage of each minority that passed last year’s WASL, according to state Office of Superintendent of Public Instruction. You can sort by school district, grade and subject.

Why don't the averages equal 100 percent?

"The one bar on the chart doesn't equal the average."

"Everybody is below the school average!"

There are two students in a class. The first student scored 50%, and for race chooses "A". The second student scored 70%, but did not specify a race.

The school average is 60%. (Two students: 50% and 70%.) For race "A", the average is 50%. (One student: 50%.) This is why the school average may not equal the average for a single group of students.

"The averages don't match up."

There are three students in a class. The first student scored 50%, and for race chooses "A". The second student scores 70%, and for race chooses "A". The third student scores 90%, and for race chooses "B".

The school average is 70%. (Three students: 50%, 70%, and 90%.) For race "A", the average is 60%. (Two students: 50% and 70%.) For race "B", the average is 90%. (One student: 90%.)

Incorrectly, if you average each race ("A" with 60%, "B" with 90%) you get 75%, which is not the school average of 70%.
