Archdiocese of Chicago Adopts Curriculum Associates’ i-Ready® Diagnostic for Grades K–2

The Archdiocese of Chicago has adopted Curriculum Associates’ i-Ready Diagnostic for Grades K–2. The Archdiocese will implement the online program as a formative assessment for both reading and mathematics starting in the 2020–2021 school year.  

The implementation of i-Ready Diagnostic across Grades K–2 comes after a multiyear pilot of the program. During the 2018–2019 school year, the Archdiocese of Chicago used the program in 15 schools and then expanded to 81 schools during the 2019–2020 school year. 

The Diagnostic provides educators with actionable criterion-referenced and normative data. Teachers administer the Diagnostic at the beginning of the school year to chart a course for their instruction and to personalize i‑Ready instructional paths. A midyear and end-of-year Diagnostic helps students and teachers measure growth and have data chats. Teacher-led and online instruction continues throughout the year to help students address their learning gaps and access grade-level learning.
