About Us

Really Great Reading believes that every student has the right to appropriate, high-quality, foundational-skills reading instruction. We are focused on preventing and remediating decoding weaknesses in students in all grades (and even adults). We provide educators with the tools and knowledge to teach all students (not just those who learn easily) to read. We make assessment and grouping practical, efficient, and accurate. Our approach to reading instruction is research-based, interactive, explicit, structured, and multisensory. In our lessons, students not only learn to read, but enjoy the intelligent and age appropriate learning process.
