This study aims at studying the validity and reliability of Arabic Jordanian version of (The Transition Assessment Profile/ TTAP) in order to diagnose children with ASD (Autism Spectrum Disorders) in Jordan. The study sample consisted of (100) intentionally chosen children all of whom had been diagnosed with ASD with an age range between (12-30) years old. Moreover, the study aimed at analyzing the validity and reliability of the translated version of (TTAP) to support its suitability to the Jordanian culture. Several statistical procedures were implemented to extract the validity and reliability indicators of the translated version including means, standard deviations, t-test, Pearson's Correlation Coefficient, Cronbach's alpha, and Guttman scale. Results of Content and Construct validity using correlational coefficients between the performance on the scale and the total degree were between. (0.40-0.85) and considered to be sufficient. Consequently, results of internal consistency using Cronbach's alpha analysis were (0.56-0.77) and considered to be acceptable for the purposes of this study. The reliability of T-TAP scale using Guttman scale was between (0.91-0.97) and additionally considered good and acceptable. Finally, results of split - half method were (0.905) and considered to be high and acceptable value for the purposes of the current study. In light of the study findings, it would be highly recommended to use the scale in Jordanian special education centers in order to develop effective transition plans for children with ASD.
