DAYC Developmental Assessment of Young Children
Who Can Administer? “Examiners who give and interpret the DAYC should have formal training in assessment.” “Training should result in thorough understanding of testing statistics and general procedures governing test administration, scoring and interpretation.”
How Long does it take to administer? • Each subtest can be completed in 10-20 minutes. • Overall assessment one hour
What Areas Does DAYC test? • Physical Development (combines fine and gross motor) • Communication (combines expressive/receptive) • Adaptive • Social-Emotional • Cognitive
Cautions • Physical Development and Communication • Scattered Skills
Age Birth to 5 years 11 months
Adjusting for Prematurity When testing a premature child, use the child’s chronological age for determining standard scores. An adjusted age may provide helpful clinical information to write an Informed Clinical Opinion.
Administering Procedures 1 Observation Interview Direct Assessment 2 3
Observation The examiner may observe the child at play or interacting with the caregiver to determine if the child has specific skills. Example: • Tells caregiver of toilet needs in time to get to the toilet. • Crosses street safely.
Interview The examiner may go over test items with caregivers for skills unable to be observed or assessed at that time. Example: • May ask the caregiver if the child sleeps through the night.
Direct Assessment Several items require that the examiner test the child directly. Example: • Matches simple shapes, such as circle, square, triangle.
Where to Start the Test Each subtest is broken down into brackets indicating the starting point.
Scoring • Items are “Passed” or “Not Passed” • Passed items earn a 1 point • Not passed are scored 0
Basal 3 consecutive 1 items The True Basal is the one closet to the ceiling
Ceiling 3 out of 5 items are failed The true ceiling is the one that is closet to the basal
Raw Score Example A: 34 How: Last number of Basal is (32) + all “1” between the basal and the ceiling (2) = 34 (credit given to 25 because it fell bellow the basal) Example B: 19 How: Last number of basal (14) + all “1” between the basal and ceiling (5) = 19 Example C: 15 How: No basal was established (common with severe kids) All points were summed =15 Example D: 34 How: Examiner should have started at item 30 (due to age) and stopped when achieved ceiling. Test is always scored as if the basal and ceiling had been attained properly. Last number in basal (32) + all “1” between basal and ceiling (2) = 34
Converting Raw Score to Percentile Step 1: Take Raw score (example Cognitive for 11 month old: 14) to Appendix A
Converting Raw score to Percentile Cont. Step 2: Take Standard Score (94) to Appendix C (percentile conversion chart)
