Developed by Project ELITE2, this implementation manual provides guidance for future replicators of the model, which may include district leaders, educators, and other stakeholders interested in implementing a multitiered system of support model for English learners in the primary grades. The manual includes a description of the model and how it was developed, tested, and adapted; key personnel necessary to support the model; professional development required to implement the model; resources necessary for coordination; and strategies for implementing and sustaining the model over time. Formative and summative evaluation measures and data are also included. The manual also describes all project-designed tools and deliverables, including a complete roster of the available professional development training and the instructional guides required for implementation, support, and sustainment.
