It is wise to continue with the selected program until the learner is at least one year ahead of his grade level in his area of difficulty. The minimum time that is required to achieve this is about one year, but it can take up to two years if the learner has severe learning problems.

 If one discontinues the program before the foundational skills of reading, spelling, writing and math have been thoroughly automatized, there is the danger of a relapse. On the other hand, once the foundational skills have been automatized and the learner is clearly no longer behind in his reading, spelling, writing, and math, the problem will not return if the program is discontinued.
