There are children in this age group who not only repeat and prolong sounds markedly, but also struggle and become tense and frustrated in their efforts to talk. They need help. Without it, their stuttering problem will probably adversely affect their classroom performance. As suggested with the preschool child, consult with a speech pathologist as well as with the parents and discuss your observations with them. If you, the parents, and the speech pathologist agree that this child's disfluencies are different from other children in your classroom, you may decide as a team to evaluate the child for stuttering.
A major concern for most teachers is the child's reactions to his stuttering in the classroom. How should the child be expected to participate in class? The answer to this question depends on the individual child. At one extreme is the child who may be quite unconcerned and happy to participate like any other child; at the other extreme the child who will cry and refuse to talk. Most are somewhere in between. If the child is being seen by a speech pathologist, find out her opinion about reasonable expectations. Also, ask the child how he would like to participate. Sometimes participation requirements become part of the child's IEP.
