Early identification of social-emotional challenges can make all the difference to a young child. The proof is undeniable: the earlier a behavioral concern is identified, the greater the chance a child has for reaching his or her full potential in life. This is the driving force behind Ages & Stages Questionnaires®: Social-Emotional, Second Edition (ASQ®:SE-2)—a parent-completed, highly reliable system focused solely on social-emotional development in young children. Accurately identifying behavior through ASQ:SE-2 paves the way for next steps—further assessment, specialized intervention or ongoing monitoring, for examples—to help children reach their fullest potential during their most formative early years.
