The purpose of the study was to analyse differences in speech, language and communication skills between students with mild intellectual disabilities using a narrative text written in easy-to-read text (experimental group), and students with mild intellectual disabilities using a book containing the same content but written in ordinary text (control group). The results indicate that students with mild intellectual disabilities who listen to the easy-to-read text exhibit superior communication skills in individual conversations with the teacher. Significant differences occur in all three measured variables. The research is important contribution in understanding of benefits of easy-to-read texts.
