A diagnostic reading assessment, based on the Science of Reading, to inform instruction & intervention. Now including Lexile™ measures!
Most secondary reading assessments miss critical skills or take too long to administer. Capti ReadBasix changes that. Choose which skills to assess, saving valuable instructional time while getting actionable data to drive reading growth.
ReadBasix is the only assessment designed specifically for middle and high school students that identifies those reading below the decoding threshold - a critical barrier to comprehension. Our research-based tool evaluates 6 foundational reading skills, including silent decoding of multisyllabic words, in under 10 minutes per skill.
Developed by ETS literacy researchers and grounded in the science of reading, ReadBasix delivers comprehensive insights for screening, diagnosis, RTI/MTSS planning, progress monitoring, and Lexile® matching. Our expert Literacy Team partners with your teachers to interpret data and optimize existing curricula and interventions.
