Best practice suggests that curricular decisions be made on the evidence base of the content and the contextual fit of the curriculum to the school setting, and with coaching to help teachers effectively use curricula. Messages from the federal government encourage school administrators and researchers to consider the costs of a program. The Middle School English Learner Project, an evaluation of the "Direct Instruction Spoken English" curriculum, provides the opportunity to document and analyze the cost-effectiveness (CE) of a high-quality implementation of one English language program. Results indicate that the majority of costs are associated with training and coaching, with potential economies of scale through training multiple teachers together. Importance of using CE analyses to inform decisions is discussed.
