Abstract
This study created a definition of instructional program coherence by analyzing the factors that promoted or inhibited the coherent implementation of an instructional program. The study sought a solution to the tension created by system demands for instructional coherence versus school site demands for instructional variability. Roger C. Everett's Diffusion of Innovation theory provided a framework that guided the methodology, analysis of findings, conclusions, and recommendations. The crucial role of reinvention in sustaining innovations in large, urban school districts was noted.
