I have a student who has been stuck around a 1.5 grade level in reading. Recently I started working with him in small group with Reading Horizons. That meant he was getting whole group Reading Horizons, the Reading Horizons Discovery computer program, and kind of like an intervention of Reading Horizons that was on a lower level than my whole group lesson. In one month, his level went from a 1.5 to a 2.8!!!!
