Full levels can be purchased from the in-app store. Five years of solid research have been completed through the University of North Carolina at Charlotte, proving ELSB to be a highly effective literacy program and more effective than a sight-word only program.

All students begin at Level 1. Instruction is one-on-one or in small groups. Teach scripted lessons daily in two 30-minute sessions. On the completion of each level, formal assessments are given.
