Which of the following is a parent-completed questionnaire?

The Age and Stage Questionnaire is a parent-completed questionnaire designed to help assess children’s development at various stages. It allows parents to provide insights into their child's skills and milestones across different areas, including language, gross and fine motor skills, and social-emotional development. This tool is valuable for speech therapists and other professionals to gauge a child's developmental progress and identify any potential concerns.

The Child Behavior Checklist, while useful, focuses on behavioral issues rather than a broad developmental approach and is not completed solely by parents. The Receptive-Expressive Emergent Language Scale evaluates language skills directly through interactions and assessments, rather than relying on parent input. Similarly, the Preschool Language Scale involves clinician-led assessment rather than parent completion.
