The article draws on cognitive science research to clarify the five pillars of effective reading instruction — phonemic awareness, phonics, fluency, vocabulary, and comprehension — and explains how each must be explicitly and systematically taught, with accountability for outcomes, rather than incidentally encountered. It directly addresses the concern among educators that "science of reading" has become marketing language, arguing that the discipline is defined by alignment to research evidence, not branding — a distinction that Really Great Reading (RGR) and CEO Karl Rectanus make central to every district partnership and public platform. The piece supports the broader national conversation about what implementation fidelity actually requires to produce measurable literacy outcomes.
