Hi Richard, The connection between acceptance and success revolves around retention. If students don't feel a part of the class structure or that the instructor doesn't care about their success then it is much easier to drop out. It reinforces their decision to quit because it isn't their fault it is the fault of the college or the instructor. Our culture is into blame shifting so the students are well versed in such a technique. By helping the students to become involved in the course and feeling a part of the learning community the dropout factor is reduced. The scientific or statistical method used is based upon accrediting standards that set the bar for what constitutes a successful program completer. Some students are motivated to the level that being accepted into the class or by peers does not matter. They have their personal goals and will efficiently work toward achieving them not matter the setting. Generally the numbers are not to high for this group. Gary
