ReadTheory
ReadTheory is a web-based platform for personalized reading comprehension practice. A benchmark assessment identifies a student's reading level, then the platform adjusts practice as the student works. Its library includes thousands of fiction and nonfiction texts aligned to standards, alongside printable materials and tools for creating custom content. Reports cover Lexile and grade levels, ELA standards, and student progress history. The platform serves K–12, ESL, and special education learners, and the School & District plan is aimed at schools and districts. Browser-based access is designed for Chromebooks, tablets, and Windows or macOS computers; phones are not optimized for student use. Integrations listed include LMS, LTI, and rostering, with single sign-on through Clever, Google Classroom, and ClassLink. ReadTheory says student personal information is not sent to third-party AI systems or used to train AI or machine-learning models. The free Basic plan covers one staff member and 30 students with limited quizzes and progress history. School Champion costs $40 a month for one staff member and 40 students, with unlimited quizzes and progress history.
