Academics
No test results are reported for this school (it may not have tested grades, or groups were too small to report).
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.

Low-income students62% · A larger share than at about 7 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?
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?
