The purpose of this research is to study the Sample of Vocal Behaviour Record Form (SVBRF), included in the third edition of Autism Screening Instrument for Educational Planning-3 (ASIEP-3), and the psychometric properties of the trucked forms for the informal assessment tools of Autism Screening Instrument for Educational Planning-3 (ASIEP-3). The rationale for the research is the lack of standardised informal assessment tools to use for the educational assessment of children with Autism Spectrum Disorder (ASD) in Turkey. The study group consists of students, who receive education at three private institutions for special education and rehabilitation. A total of 169 students were included in the study group of the Turkish Version of the SVBRF, 54 females and 115 males. And in the study group of the Turkish Version of the IARF, a total of 115 students were included, 37 females and 78 males. The data, which were obtained from the study requiring data collection based on performance feedback, were analysed in order to assess the validity and reliability of the tools. The findings from the analysis revealed that both tools were valid and reliable to be used for obtaining the samples of vocal behaviour of children with ASD, and evaluating their level of social interaction.
