Achieve3000® impacts on student reading and STAAR EOC English I, English II, and Biology exams for the 2014–2015 academic year.

The Houston Independent School District completed a 2015 study focused on ninth and tenth graders to assess the impact derived from the use of Achieve3000’s reading solutions on (1) the change between students’ pre- and post-test Lexile scores as measured by LevelSet™, (2) students’ scale score performance on the State of Texas Assessment of Academic Readiness End-Of-Course (STAAR EOC) for the English I, English II, and Biology exams, and (3) students’ probability of meeting both the Phase-in 1 and Phase-in 2 passing standard on the STAAR EOC English I and English II. Results suggest that the more students use Achieve3000’s web-based software, the greater their gains in post-test Lexile scores, the greater their achievement on the STAAR EOC exams, and the higher their probability of meeting the Phase-in 1 and Phase-in 2 passing standard on the STAAR EOC exams.
