Developmental delay refers to delayed development in areas such as motor skills, language, cognition, social skills, or other areas compared to other children. Assessment of developmental delay involves gathering information on a child's strengths and weaknesses across all developmental domains from medical professionals, therapists, teachers, and the family. The needs of children with developmental delay include extra help and support to develop skills through a nurturing environment that simplifies tasks, values their efforts, and uses multiple learning methods appropriate for their level of understanding.
