The primary focus of this domain is on demonstrating a comprehensive understanding of ASD to address social and ethical issues in education professionally and ethically. Evidence should showcase how educators apply knowledge of ASD definitions, identification, placement options, and historical and current trends to foster individualized education and life planning. It should highlight the use of individual strengths to enhance communication and social skills through assistive technology and communication aids, emphasizing self-determination, self-advocacy, and active family and community engagement. The goal is to improve the overall quality of life for individuals with ASD.
