Free High-Quality Resources and Tools for Reading Comprehension

As a nonprofit organization, ReadWorks creates and delivers this entire website for free! 

Our resources focus on the following areas of reading comprehension: 
  • Building Background Knowledge 
  • Growing Vocabularies 
  • Strengthening Strategic Reading

Powered by the Science of Reading

We firmly advocate for the transformative potential of collaborative partnerships with educators in rigorously studying our instructional methodologies and support tools through comprehensive, multidimensional research. Empirical evidence underscores that ReadWorks significantly enhances students' reading proficiency, aligning with Tier-3 promising evidence criteria outlined by the US Department of Education's Every Student Succeeds Act. Particularly noteworthy is the demonstrable efficacy of ReadWorks' differentiation tools in addressing the unique needs of learners in under-resourced educational settings.
