i-Ready Diagnostic & Instruction

i-Ready Diagnostic & Instruction is an interactive online learning program that helps students build essential skills in reading and mathematics. i-Ready starts with an online diagnostic test that students take in class or remotely to identify the specific skills each student needs to develop and measure academic growth throughout the school year. i-Ready encourages students to take ownership of their learning. Students get real-time feedback, see motivating messages, and the engaging environment draws students in right away and gets students of all ages excited about learning. The California Department of Education (CDE) has identified i-Ready as an approved diagnostic assessment tool.
