We are currently using the Barton System. My educational consultant, who is also a tutor, told me the same as the PP…. 2 hours a week. I’m not sure if every child who goes to a tutor is going that often. That is definitely for the parents who are purchasing the program and using it at home. Actually, those two hours are for the summer. Because of the level of difficulty with my daughter, during the school year I need to do more. She recommended 45 min. to an hour daily when possible. If your child is mild, maybe tutoring once a week would be sufficient. If your child is homeschooled, you have an advantage. You can adapt the reading to the Barton System. My consultant said that the kids she tutors who go to school are forced to read, so when they go to be tutored, they actually need to be retrained. So, mixing other reading while doing this system is not beneficial. The reading needs to be controlled. My whole language program for this next school year is going to be Barton. I will not use any other English, spelling, or writing program. It’s costly, but sells again for a good price. I felt I didn’t have any alternative because my daughter was just not progressing in her reading and her spelling is not good. (Barton is praised for making good spellers) We started at the bottom and are working up. So, far, she is doing well:)
