Sixteen subjects were surveyed to determine their perceptions of four communication techniques used for increasing language in preschool children with autism: Picture Exchange Communication System (PECS), Enhanced Milieu Teaching (EMT), Voice Output Communication Aid (VOCA), and Applied Behavior Analysis (ABA). The subjects included public and private special education teachers of children with autism. A self-developed questionnaire was used to collect data. Descriptive statistics and Chi-square (X2) were used to analyze the data at .05 significance level. PECS was the technique used most often. ABA was the technique perceived as most effective. Significant relationships were found between choice of communication technique and level of education and years of teaching experience. Limitations and implications for future research are discussed.
