Many Clinicians Have Observed That It Is Difficult for School

Many clinicians have observed that it is difficult for school age children to eliminate stuttering, or even make appreciable progress. The best explanation for this phenomenon is that:

A) current therapies have been adopted from those designed for adults; they are not adequate for the specific conditions of stuttering in school age children, especially their slow to develop fine motor skills
B) the nature of the school environment, such as uncooperative teachers and peers' negative reactions
C) children who did not exhibit natural recovery at an earlier period represent a more resistant type of stuttering
D) the important element of parental involvement in the therapy, so essential in the treatment of stuttering in preschool children, is either missing or rather weak in the routine therapy provided in the schools
