A study examined whether a half-day or all-day kindergarten readiness program was the more beneficial in preparing students for kindergarten. A questionnaire was drawn up after research into this domain and submitted to 45 faculty members at a child development center. The findings were found to be somewhat evenly divided between the half-day and all-day readiness programs. However, the results provided small but significant evidence in favor of the half-day program as indicated by both the half-day and all-day teachers regarding the acquisition of learning skills, readiness skills, and social skills. The half-day program seemed to be better for the 4- and 5-year-old child, if a choice is available. Results also indicated that readiness and social skills are learned in the morning when a child is rested. (The questionnaire and a progress check list for the 4-year-olds are appended). (AA)
