Characteristics of Typical Disfluency and Stuttering

Differentiating typical disfluencies and stuttering is a critical piece of assessment, particularly for preschool children. Without proper intervention, children who exhibit signs of early stuttering are more at risk for continued stuttering. The chart below describes some characteristics of "typical disfluency" and "stuttering" (Adapted from Coleman, 2013).
