“A Remarkable Predictor of Your Students’ Success”


“I have been very impressed with the i-Ready program. It is a wonderful review tool. It is also autonomous and can detect with great precision where my students are academically. One of the most important aspects of this program is its ability to precisely diagnose my children's specific skills needs and continue to assign these skills to that particular student.”
