In assessing an eight-month-old with developmental delays, which guideline is most appropriate?

• A. The evaluation should be administered in Annika's natural environment.
• B. The evaluation should be conducted in 10-minute segments, with breaks in between.
• C. Annika's parents/guardians should be asked to provide props to use during the assessment.
• D. Annika's parents/guardians should remain outside the testing room.

Answer: (A)

Assessments for infants are most informative when they happen in the child’s natural environment. Observing an eight-month-old during typical routines and familiar play allows you to see how they actually use motor, social, and communication skills in daily life, not just in a clinical setting. This ecological validity helps you understand real functioning and how the child interacts with caregivers, objects, and routines, which is crucial for planning supports and favors accurate interpretation of delays.

Having parents present is part of this approach because they can describe routines, prompt behaviors, and provide important context that reveals functional abilities. In contrast, testing away from the caregiver or in a way that limits natural interaction can make the child’s behavior less representative of everyday life. Short, segmented testing or requiring parents to bring props can further disrupt natural play and routine observations, reducing the usefulness of the assessment.
