If the measured developmental level is higher than the predicted developmental level, then the treatment is considered effective by prediction analysis. Prediction analysis is not always reliable and is not a rigorous evaluation of a treatment. In addition, though the children in the Colorado Health Science program made some progress in the areas of cognition, language, fine motor skills and social skills, these skills never came close to reaching age appropriate levels. Like the Colorado Health Science outcomes, these gains were based on a form of prediction analysis. However, it is not clear if these children required any supports in these classes.
Some school districts mandate full inclusion.
Walden also observed that language use tripled after treatment. However, if a child was using only a few words prior to treatment, this may not be a significant gain. No measures were taken to show if improvements were made in the areas of cognitive function, social skills and behavior. In conclusion, none of these four programs have published treatment results that come close to matching those achieved by Lovaas and his colleagues. However, since the basis for these claims can vary greatly, these treatments must be held to a higher standard.
