RAVE-O is an extensively researched, evidence-based program that is designed to build the foundational skills that contribute to fluency and deep reading comprehension. Each lesson in RAVE-O teaches students strategies that develop skills in multiple aspects of reading including phonics, vocabulary, syntax, and morphology. It represents an example of the best application of principles underlying the science of reading and of emphases on literature. Originally developed under NICHD in 2012, RAVE-O has been updated based on new research into a streamlined curriculum with digital components for teachers and print for children
