The overall educational strategy used by the Nova High School of Broward County was to use all of the major educational innovations, such as team teaching, individualized instruction, and flexible student grouping, which had been developed and tested in separate schools during the 1960's. Since the Nova Plan is essentially a trial combination of these separate innovations it was evaluated as a whole. The evaluation can be characterized as a causal-comparative study in which changes over two-year periods in the achievement and school related attitudes of two sequential sets of Nova students were compared with changes in the achievement and attitudes of students from other county schools. A crucial finding of the first year of operations was that the Nova Plan could not be implemented under the conditions of an overcrowded school plant, or even under an enrollment based on the ratio approaching but one seat per student per instructional unit. The problems surveys indicated an acute lack of effective vertical lines of communication between teachers and administrators, and of horizontal lines within faculty and administration separately.
