This study looks at students attending Kean University studying Education and their knowledge of selective mutism. Selective mutism is a rare disorder that is first detected when the child enters school, and is often mistaken for shyness. It is important that future educators are aware of the characteristics of selective mutism and what they can do to ensure that their students get the help they need. The objective was to examine students' knowledge before and after information on selective mutism was provided. Two classes at Kean University were randomly assigned to receive either a PowerPoint presentation or a handout. Each class completed a pre-assessment questionnaire, received their respective intervention, and then completed a post-assessment questionnaire. Results showed Group A had a higher increase between the pre-assessment and post-assessment mean; however, Group B had higher initial scores overall. The difference in the total means for Group A was not statistically significant, but the difference between Group B's scores was statistically significant.
