This 2007 brief provides an orientation to the Content Literacy Continuum (CLC) model a replicable district-level model of instruction to meet the differentiated needs of struggling adolescents. CLC is a five-level model that is aligned with a 3-tiered RTI instructional model that takes a systems approach to providing adolescents with literacy instruction and intervention. The goal of the model is to decrease the achievement gap, improve adolescent retention, and provide teachers with specific methods of instruction. The brief provides an overview of different stakeholders' role in planning and implementing the model and gives specific literacy strategies and interventions that might be used. The brief was written by Leslie McPeak and Lisa Trygg for the Stupski Foundation.
