Creating meaningful change in a state's education system from the capitol to the classroom is complex and challenging work. Over the past several decades, considerable research, policy, and funding have focused on the use of evidence-based programs (EBP) in schools. However, these practices only are effective when fully and effectively implemented by teachers in the classroom, so all students can benefit. One may ask, how can a State Education Agency (SEA) actively promote and support organizational and systems change and assess the effects of change on a large scale? The answer may lie in a logic model informed by implementation science and characterized by multi-level supports that interact. The Cascading Logic Model helps states define and operationalize the infrastructure needed for effective statewide implementation of EBPs. In a Cascading Logic Model, each independent variable (input) is a dependent variable (output) at the next level. This brief outlines a Cascading Logic Model approach to analyzing and planning for the infrastructure and supports needed.
