The Full-Day Kindergarten (FDK) Program was implemented in selected Columbus (Ohio) Public Schools to improve students' level of achievement by providing an additional half day of kindergarten. This extra half day gave pupils time to participate in more language enrichment activities and more group learning. Activities were designed to: (1) enhance pupils' growth and achievement; (2) provide instruction in performing and creative arts, humanities, and ethics; (3) provide physical fitness and health activities; and (4) involve students in community service projects. Pupil census information indicated that the FDK served 985 kindergarten pupils for an average of 27.5 hours of instruction a week. In 1990-91, the FDK was evaluated in terms of student gains in reading and oral comprehension skills. The evaluation was based on pupil census information and pre- and post-test scores on the Comprehensive Tests of Basic Skills. It was found that 77.6% of the FDK pupils attended 89 days, or 80%, of the entire instructional period. Over 65% of the students with 80% or higher attendance levels gained 3.0 or more normal curve equivalent points in total reading and oral comprehension. A total of 69.4% of the pupils were rated by their teachers as making "much progress." It was recommended that in-service meetings be scheduled during a time when most teachers are free to participate and that the program be continued. Sample records and evaluation forms are attached.
