An instrument intended to identify and monitor normal development or possible developmental delay is known as what?

The correct response is screening, as it specifically refers to a process designed to quickly determine if a child is developing appropriately or if there are any signs of developmental delays.

Screening instruments typically consist of standardized tests or checklists that are applied to a large group of children to identify those who may benefit from further evaluation or intervention. They are generally brief and easy to administer, allowing for the identification of children who may be at risk or who may require additional support in their development.

In contrast, assessment generally refers to a more comprehensive approach that involves gathering detailed information about a child's functioning and capabilities, which goes beyond just identifying potential delays.

Evaluation is a formalized process that often entails in-depth assessments that look at various aspects of a child's development or skills for the purpose of making clinical decisions.

Observation, while it is a critical part of understanding a child's behavior and development, pertains more to watching and noting behaviors rather than using a structured tool to identify potential concerns.

Thus, screening stands out as the correct answer because its primary purpose aligns directly with identifying and monitoring developmental progress, making it pivotal in early childhood interventions.
