The news that 100% of the 11th graders opted out of the test was first reported on an education blog.
Earlier this year, teachers at Nathan Hale passed a resolution against in the Common Core Standards test, but SPS Superintendent Larry Nyland threatened teachers with the loss of their teaching licenses if they didn't administer the test, according to the Seattle Education blog.
There are two more days of testing next week, according to SPS spokesperson Stacy Howard. She said the district would address the opt out numbers once testing was finished.
SPS reported that over 100 juniors also declined to take the test at Garfield High School earlier in April, and a number of parents and teachers have spoken out against the exam.
