What is ReadTheory?
ReadTheory is a free, adaptive reading comprehension platform designed for students in grades K–12, ESL learners, and adult education programs. It uses smart technology to meet each student at their current reading level and automatically adjusts passage difficulty based on performance—so no two students have the same experience unless they’re truly at the same skill level. Trusted by over 700,000 teachers and used in 40,000 schools worldwide, ReadTheory turns practice into progress with instant feedback, engaging content, and real-time data.
Whether you're a teacher looking to differentiate instruction or a parent wanting to support your child’s literacy growth, ReadTheory makes it easy to build stronger readers without extra grading or prep time. With thousands of standards-aligned passages and built-in motivation tools like badges and class competitions, students stay engaged while developing critical ELA skills like inference, summarizing, and vocabulary in context.
