Research Base

Leveled Literacy Intervention, Grades K–2 (Levels A–N)

The development of LLI was driven by what prior research has established about how children learn to read, and what works best with struggling readers. Please refer to the research base for more information regarding the background research that provided the foundation for the development of this intervention system. 

Leveled Literacy Intervention, Grades 3–5+ (Levels L–W)

In this summary, Irene Fountas and Gay Su Pinnell review the research base for the Red, Gold, and Purple systems, which is designed to lift the literacy achievement of students who are falling below grade level expectations in reading. The 15 principles on which the LLI Red, Gold, and Purple systems are based are discussed, along with a list of supporting research. The lesson framework for the extended systems of LLI rests on these principles.
