The objective of the study was to construct an instrument that allows measuring the perception of the communicative skills of young people with intellectual disabilities in a valid and reliable way. A descriptive study (Survey) of cross section was carried out. Sixty microentrepreneurs from the province of Talca (Chile) were studied. The work activities are for bakery, furniture and sales in grocery stores. A questionnaire was constructed to measure the perception of the communicative skills of young people with mild intellectual disability. It was validated by construct and reliability was verified by Cronbach. The validity results show values of Kaiser-Meyer-Olkin 0.78, X2 = 1031.500. Three indicators or categories were confirmed, whose saturations range from 0.52 to 0.83. The Percentage of the variance explains 65.90%. The alpha of Conbach showed a high capacity of reproducibility (r = 0.92). In conclusion, the elaborated instrument that measures communication skills is valid and reliable. The results suggest its use and application in microentrepreneurs to assess the perception of the communicative skills of young people with mild intellectual disability.
