This year my school adopted Phonics Boost and Phonics Blitz to use as our intervention program in grades 3-5. I have absolutely fallen in love with your program! We have experienced so much success. The kids are reading with 98-100% accuracy and their reading rates have also improved.
I have used Scott Foresman ERI, Voyager Passport, Read Well, and the Elements of Reading kits. None have had the level of explicit, direct, and systematic phonics instruction that your program provides.
