Really Great Reading Company, LLC

Really Great Reading is a privately held company specializing in providing evidence-based literacy solutions and foundational literacy curriculum to educators. Headquartered in Cabin John, Maryland, its mission is to equip educators with proven tools that drive measurable student outcomes, aiming to change America's literacy trajectory.

The company offers a comprehensive suite of proprietary products, including instruction, assessment, practice, and professional development, designed for students from PreK through high school. Key programs like Countdown, Blast, HD Word, and Boost address various aspects of literacy, from foundational skills to remediating decoding weaknesses. Really Great Reading also provides free diagnostic assessments and grouping matrices, and has expanded its offerings through partnerships with OxEd & Assessment for oral language solutions and the acquisition of InferCabulary for vocabulary programs.

Led by CEO Karl Rectanus, Really Great Reading maintains a strong market position as a leader in the Science of Reading movement. In April 2026, the company launched its Orbit curriculum to bridge the gap between decoding and comprehension for older students. Recent achievements include exceptional ratings from EdReports for its K-2 foundational skills programs and recognition from The Reading League for excellence in literacy instruction. The company has experienced substantial growth, expanding its reach across numerous states and impacting over 3.5 million students and 250,000 educators. Really Great Reading is backed by private equity firms, including The Vistria Group, which announced a strategic partnership in February 2023.
