Developmental screening instruments (DSIs) refer to tools used in the process of identification of a disability or delay. Screening instruments are meant to provide a snapshot of early child development. They are used to determine if there is a need for further, more comprehensive evaluation. Results from DSIs are used to make referrals for diagnostic evaluation(s), track child development, and conduct universal screening efforts.
