The third of three volumes, this document provides (1) a reduced list of child development characteristics obtained from parents, teachers, and staff participating in Head Start Input Workshops set up to identify desirable program effects; (2) a Tabulation of Importance Ratings, showing how workshop participants valued specific statements of child development outcomes; (3) a description of the method of calculating overall ratings; (4) a list of the ratings of each characteristic by various categories of participants, such as black, teachers, rural, and southwest; and (5) means and standard deviations of ages assigned to the reduced list of developmental characteristics by workshop participants. In the concluding section, J. McVicker Hunt offers a rationale for selecting preferred measuring techniques for use in assessing program effects in the cognitive domain. (Author/RH)
