i-Ready is a set of diagnostic and instructional tools for both math and English. Students take an adaptive placement test. i-Ready creates individualized instructional pathways for each student. Teachers can let i-Ready personalize instruction on its own, or they can customize the experience for individual students, groups of students, or even an entire class. Additionally, i-Ready offers teachers a range of diagnostic reports. Data is provided on growth, performance, instructional progress, and much more.  Lessons start with an overview of the learning objectives, followed by a guided learning experience. Kids can review lessons at any point but won't be able to skip ahead.
