This paper synthesises research evidence regarding enablers and barriers for children with autism spectrum conditions (ASC) in the inclusive early-years Swedish preschool context. Focusing on current norms, this chapter presents a review conducted using purposeful sampling. The Swedish preschool curriculum sets expectations for children with ASC, which can be challenging. It is therefore important to discuss how norms can hinder the development of children with ASC. Some of the core goals of the curriculum are difficult for children with impaired social skills, low impulse control, impaired perceptual ability, and hyperactivity to achieve. Understanding the challenges experienced by children with ASC, and a sound ASC knowledge symptoms among professionals, can improve the opportunities for children with ASC to develop their full potential in inclusive preschool settings. Optimal development of preschool children requires a dynamic view of each child’s challenges and strengths, and expanding existing norms to create more inclusive learning environments in the future.
