Our assessment and instructional products are grounded in research and designed by experts to deliver rigorous instruction and comprehensive support to help students at all levels from all backgrounds. Every program we create starts with an extensive research base and is followed by a continual cycle of research, review, and improvement. i-Ready Personalized Instruction has been studied by numerous third-party and independent organizations, as well as Curriculum Associates’ own Research team, in partnership with educators throughout the country. This growing body of research demonstrates how i-Ready Personalized Instruction improves the reading and mathematics skills of students across the country in Grades K–8.

i-Ready works by supporting students and teachers all year long with assessments and instruction. The first Diagnostic of the school year assists teachers in charting a course for their instruction and drives i-Ready Personalized Instruction paths for each student. A midyear and end-of-year Diagnostic helps students and teachers measure growth and have constructive data chats about progress and goals. Teacher-led and personalized instruction continue throughout the year, addressing class and individual needs, while i-Ready Standards Mastery helps teachers determine students’ mastery of grade-level standards.

The i-Ready Diagnostic is a test designed to help teachers support each student and create a path of personalized instruction for every learner. The adaptive test adjusts its questions to suit each student’s needs. Each item a student sees is individualized based on their answer to the previous question. For example, a series of correct answers will result in slightly harder questions, while a series of incorrect answers will yield slightly easier questions. Students will find the test difficult, but that is OK. Think of it like a vision test: the blurry letters and incorrect answers help the eye doctor find the correct glasses for you. The i-Ready Diagnostic gets harder until a student answers an item incorrectly and then narrows in on exactly where a student needs support.
