There are other systems - Wilson Reading and Paula Tallal's program (she's at Rugters, I think) come to mind. For certain kids, it is VERY successful. Since it is very structured, very predictable and very systematic, it gives kids a way to control exactly how to approach a reading task and to be consistent in their work. It gives them rules and practices to follow so they have a 'manual' for how to attack their reading. So, for kids who need that, it works great! Some of my older kids or kids who did not need the level of prescription and regimentation of Orton Gillingham did not like it as much and had difficulty following the rules consistently. That being said, it has been a godsend for many of my students - particularly the younger ones who can get the skills early and carry them forward. I stay current by using it, by being a memer of the local Orton professional association and by attending their annual conference.
