Curriculum Associates' i‑Ready® Diagnostic Receives Highest Ratings from the Center on Response to Intervention

Online reading and mathematics assessment for Grades K–12 meets high psychometric and screening standards

Boston, MA, August 1, 2016

Curriculum Associates' i‑Ready® Diagnostic for Reading and Mathematics recently received the highest ratings on the Screening Tool chart from the Center on Response to Intervention (Center on RTI) of the American Institutes for Research. The ratings signify the validity and reliability of i‑Ready Diagnostic as a K–12 assessment that meets high psychometric and screening standards.

The Center on RTI is a national leader in supporting the successful implementation and scale-up of RTI and its components. Its Technical Review Committee reviewed i‑Ready Diagnostic based on its Classification Accuracy, Generalizability, Reliability, Validity, and Disaggregated Reliability, Validity, and Classification Data for Diverse Populations. The program received the highest possible designations— “Convincing Evidence” or “Broad” —across all of these technical standards.

i‑Ready Diagnostic also recently received near-perfect ratings on the Academic Progress Monitoring Tool chart by the National Center on Intensive Intervention (NCII) of the American Institutes for Research. NCII is a nationally recognized technical assistance center that supports the implementation of data-based individualization in Reading, Mathematics, and behavior for students with severe and persistent learning and/or behavioral needs. Collectively, the ratings from the Center on RTI and NCII signify the high quality of i‑Ready Diagnostic as a screening and progress monitoring tool that meets strong technical standards.

“We are very proud of the ratings we’ve received from the Center on RTI and NCII,” said Rob Waldron, CEO of Curriculum Associates. “They represent both the commitment to excellence and intensive research that our team put into making i‑Ready Diagnostic the most reliable assessment choice for schools and districts.”

The i‑Ready Diagnostic ratings are available on the Center on RTI website at
