Summary Comments: Strengths: Ease of administration, High inter-rater reliability, provides separate norms for subgroups, uses a curve that approximates a growth curve for ease of use relatively short testing time addresses four areas of development has a behavioral scale Weaknesses: The DDST-II is a screening tool and is not a diagnostic tool.
