Apex Learning is the largest provider of secondary digital curriculum in Houston Independent School District (HISD). Introduced in January 2010 through Graduation Laboratories (Grad Labs) located at each high school, the program has grown from providing seniors with opportunities to recover credits required for graduation to providing secondary students with options for completing both recovery and original credit courses in grades 6-12. This report documents usage and academic achievement associated with courses completed through Apex Learning in 2011- 2012 and 2012-2013. It also addresses the completion of Apex Learning Texas Assessment of Knowledge and Skills (TAKS) and other providers' State of Texas Assessment of Academic Readiness (STAAR) review courses, courses offered only at schools that elect to fund the services to support students who need to retake state-mandated tests. Finally, with the addition of Apex Learning Advanced Placement (AP) course options in HISD, this report provides information about program usage and student performance on the associated AP exams compared with the performance of all other students who took AP tests in the district. Highlights in this report include: (1) In 2012-2013, 6,730 HISD students completed 12,872 online courses through Apex Learning, down from the 6,792 students who completed 14,073 online courses through Apex Learning in 2011-2012.
