So the time it takes to provide intervention for a reader who’s impaired, a disabled reader, is quite intensive. We think about first and second graders years ago, there was research done, and the research is the same, takes about two hours a day, five days a week of intensive instruction and reading to help these reading impaired readers come up and catch up to their peers. So for a program that’s going to offer you magic for 15 minutes a day or a 30 minute day program. I would be very skeptical of those programs. Do you want to look for intensity intervention? Lots of practice. So the research shows for younger children that it’s about two hours a day, five days a week for a good school year, almost a school year. It takes a lot of intervention and a lot of practice in order to help these children catch up to their peers in reading.
