LLI is now being extended to serve students reading at levels R through Z. Two new systems are in production. Purple, Levels R–W, and Teal, Levels U–Z, will provide lessons for students in grades five through eight. The development of the extended LLI systems rests on the foundation of research already completed (and ongoing) for the K–4 LLI systems. In addition, it incorporates teaching and learning approaches that are strongly supported by the research we describe in the research base.
