Notes on Psychometric Norms:
Separate norms are provided for the Parent Form by gender and age (12-17 months, 18-23 months, 24-29 months, and 30-36 months). Norms are presented this way because the authors report that age and gender differences found on scale and subscale scores suggest the "importance of comparing the scores of young children within relatively narrow age bands (i.e., 6 months) and to children of their own sex" (Carter & Briggs-Gowan, 2005 p. 50).
If Yes, Specify Cutoffs:
PROBLEM SCORES: Cut scores =>90th percentile, Of Concern T-score between 63 and 69; Clinical T>=70. COMPETENCE SCORES: Cut scores =<10%; Of Concern: T between 31 and 37; Deficit/Delay T=>30.
