Program Description

Raz-Plus, developed by Learning A-Z, is a web-based blended learning platform designed for students in grades K-5. It provides online activities, completed independently by students, as well as level-based resources and corresponding curriculum suggestions for teachers to use in supplemental whole-class and small-group instruction.

Program Outcomes

Raz-Plus was evaluated in one randomized study involving 39 K-5 teachers from three high poverty rural elementary schools in two districts in the southeastern United States. After one semester, students in classrooms assigned to Raz-Plus as a supplemental resource scored significantly higher than control students on the STAR Reading assessment (effect size = +0.14). This qualifies Raz-Plus for the ESSA “Strong” category.

Staffing Requirements

Program implemented by current ELA teachers

Professional Development/Training

Two PD sessions – one onsite training prior to program implementation and one delivered in-person or via webinar after approximately one month. Raz-Plus teachers also receive unlimited access to prerecorded online PD sessions and technical support.


Raz-Plus is a web-based program and it is available from any internet connected computer. In addition to the web version, Raz-Plus is available on iOS, Android and Kindle.
