We use it at our school. The reading department and speech pathologists choose the students based on testing results A teaching assistant has a couple of earobics groups of 4 or 5
students each on their own computer. She has to monitor them at first but after a few sessions most of the students are able to continue on their own using headphones. We don't have any data yet on progress but the first grade teachers are commenting that the students' reading skills are improving.
