It wouldn't have affected any of these test scores. Prop 58 was approved Nov 2016 and took effect July 2017[1], whereas the 2017 tests cited in this article were taken 2/3 of the way into the school year[2], which puts it in Spring for a normal school year schedule and months before Prop 58 ever took effect. Any effects of Prop 58 on testing scores won't be seen until this school year when students take the tests in early 2018.
