Understanding i-Ready


iReady empowers you by connecting rich assessment data to personalized digital learning and powerful classroom instruction. With iReady, you can sharpen your insight into student needs with actionable data and access rigorous yet engaging instruction to help each student succeed.

i-Ready Diagnostic: Get high-impact data in less time

The i-Ready Diagnostic is an adaptive assessment that identifies students’ strengths and weaknesses, measures growth, and supports data-driven differentiated instruction. It provides comprehensive insight into student learning across K–12 skills to help you meet the needs of all students.


i-Ready Online Instruction: Provide students with personalized digital support

i-Ready Online Instruction provides a personalized learning pathway for students based on their Diagnostic results. Online Instruction targets skills gaps to help students who are behind access grade-level content, and it provides challenges and enrichment for students who are on grade level.


i-Ready Standards Mastery: Measure mastery of grade-level content

i-Ready Standards Mastery lets you measure mastery of individual standards to help you understand progress through grade-level instruction, identify needs for reteaching, and determine common misconceptions and errors.


Ready® books and Ready Teacher Toolbox: Differentiate instruction to meet the needs of all learners 

Ready books and Teacher Toolbox provide rigorous instruction and practice opportunities to build confidence and promote mastery of standards. When combined with the i-Ready Diagnostic and Online Instruction, educators can further differentiate instruction in their classroom and promote even greater growth and engagement among students.
