Reduces the overall costs of the state assessment system by: (1) Implementing assessments of English language arts and mathematics developed by a multistate consortium in which Washington took part beginning in the 2014-2015 school year;

(2) Combining assessments of reading and writing into an English language arts assessment;

(3) Maximizing use of the consortium assessments in adapting the high school English language arts and end-of-course mathematics assessments; and

(4) Reducing to three the number of assessments that will be required for students to graduate beginning with the class of 2015.

Directs the tenth grade English language arts assessment and the end-of-course mathematics and biology assessments to be used to assess foundational skills that are needed for graduation.

Provides that the new college and career readiness consortium assessments, which will be administered at the end of the eleventh grade, are intended to demonstrate the level of a student's readiness for first-year college-level coursework.
