This chapter provides evidence-based assessment techniques for students with autism spectrum disorder (ASD). An overview of formative and summative assessment, innovative formative assessment strategies for students with ASD, and innovative summative assessment strategies for students with ASD are included. Discussion includes case studies and clear examples of how technology can support the assessment process. Practitioners may combine the assessment supports presented in this chapter because each support addresses more than one characteristic or need.
