What this means

“About 7 in 10” means 7 of every 10 Washington high schools have a lower number. The band is the middle half of schools and the line is the median (the school in the middle), which is not the state average. These describe who a school serves, not how good it is. What do these numbers mean?

What this means

Each year a different group of students takes the tests, so look for a direction that lasts several years, not one jump. No tests in 2019–20; the 2020–21 tests were shortened and are not shown. What do these numbers mean?

Reading these numbers: test results are the share of tested students who met the state standard; growth is the median student growth percentile (50 = typical); low-income means eligible for free or reduced-price meals. Results describe students as a group, so visit and talk to families too. What do these numbers mean?
