Small school: 75 students, so each student is about 1.3% of the school, and fewer still take each test. A few students can move a result by several points, so numbers can swing a lot from year to year.
Not reported: reading and math results are not shown. OSPI hides results to protect student privacy, for example when fewer than 10 students were tested. A hidden number is not a zero.
Points are percentage points. What do these numbers mean? Source: OSPI Report Card, data.wa.gov; tests CC BY-ND 4.0, graduation CC BY-NC-ND 3.0 IGO, as published.

Low-income students35% · A larger share than at about 2 in 10 high schools
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?
Test results over time
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. At a small school a few students can move the result a lot. No tests in 2019–20; the 2020–21 tests were shortened and are not shown. A break in the line means the result was not reported (fewer than 10 students tested, or hidden to protect student privacy). 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?
