The rate of children being diagnosed with autism is growing rapidly. Currently, 1 in every 36 children born will go on to have an autism diagnosis (Centers for Disease Control and Prevention, 2023). Teachers and early educators working with young children do not have the training required to identify children at risk for this developmental disorder. Previous research studies have successfully used brief trainings to teach parents, graduate students, and preschool teachers to use various forms of intervention strategies, identify language delays, and administer a developmental screening tool (McDonald et al., 2015; Ooesterling et al., 2019). However, for many teachers and early educators there remains no training or education about the most common neurological disorder seen in childhood, autism. The purpose of the current study was to examine the effects of providing a brief virtual training developed by the researcher called Identifying the Early Indicators of Autism to teachers. Teachers and early educators working with children ages 0-6 were recruited to participate. Teachers attended the training and completed the Autism Beliefs, Knowledge, and Self Efficacy Questionnaire before the training, after the training, and 2 weeks posttraining. Data were analyzed to determine whether or not this training increased the teachers' knowledge about autism, and whether or not the knowledge was maintained over time. The findings of the study concluded that the Early Indicators of Autism training was effective in increasing the participants knowledge about autism, per the results of the Autism Beliefs Knowledge and Self Efficacy Questionnaire. The increased level of knowledge was maintained at a 2-week follow-up. These findings are significant as they pave the way for trainings like the one used in this study to be provided to more teachers, so they can be equipped and better prepared meet the needs of their young students.
