## Overview

ReadTheory began as a free adaptive reading comprehension program and has grown into a full practice and assessment platform used by teachers, schools, and districts worldwide. Students read short passages and answer comprehension questions at their current level; the system adjusts difficulty after each answer, so a reader is always working just beyond their comfort zone rather than being stuck on content that is far too easy or far too hard. Teachers see live feedback data and can identify exactly where comprehension breaks down.

Reporting is one of its strongest draws. A single dashboard shows growth, mastery, and gaps at the student, class, school, and district level, expressed in Lexile measures, grade levels, and ELA standards. Beginning, middle, and end-of-year benchmark assessments are included at no extra cost, and schools report meaningful gains on state assessments after consistent use.

The content side combines a large human-written library of fiction and nonfiction with an AI worksheet builder that generates passages and questions on any topic in seconds. ReadTheory also keeps a strong offline component: passages, quizzes, graphic organizers, and worksheets can all be printed for small groups, substitute teaching, or any lesson where screens are not the answer. Onboarding is lightweight, with classes set up in about five minutes and no lengthy training required, and the platform is designed around student privacy and FERPA compliance.

## Pricing & Plans

ReadTheory is free to start for individual teachers, students, and parents, and the company describes its core practice as free. Paid plans exist for schools and districts that need school-wide and district-level reporting, administrative tools, and broader support; specific pricing tiers should be confirmed with ReadTheory directly or through their sales team.
