Yes. I had several students who came in to second grade as non-readers. Some not knowing all of their vowel sounds. As we have progressed in the program these students are reading, using the skills they have learned to decode words. One student in particular came in from being home schooled at below a level A in Fountas and Pinnell. After being tested in the beginning of December after just 3 full months of Reading Horizons, he is now a level D independently.
