“…Given the complex nature of ASD and the presence of severe learning and behavioral problems in individuals with ASD, preschool teachers working with individuals with ASD need to have professional competencies specific to ASD in order to carry out a successful inclusion process (Grossi-Kliss, 2006;Scheuermann, Webber, Boutot, & Goodwin, 2003;Simpson, 2004). In other words, it is crucial that preschool teachers need professional competencies in basic relevant subjects such as the characteristics of individuals with ASD, the processes of education and training for these individuals, inclusion, coping with behavioral problems, interdisciplinary teamwork, and cooperation with the family, in addition to having a positive attitude towards the integration process of children with ASD (Eldar et al, 2010;Grossi-Kliss, 2006;Lindsay et al, 2014;Mak & Zhang, 2013;McConkey & Bhlirgri, 2003;Odom & Connie, 2015;Razali, Toran, Kamaralzaman, Salleh, & Yasin, 2013).…”
