A major consideration in this study has been given to the establishment of the criteria by which the soundness of a testing program could be evaluated as its role in the secondary school. This problem was limited to the planning and administering of a progressive and comprehensive long-range testing program designed to meet the needs and problems common to most school administrators within the economic limits of a small high school. It was not the purpose of this study to anticipate the problems peculiar to particular teachers, high schools, or localities. However, the testing program if properly directed will result in the formation of subsidiary testing programs undertaken by particular teachers or groups of teachers for the purpose of throwing light on the specific problems raised by a large general testing program.

The problem of this study was to determine the emphasis placed on various science teaching practices by a random sample of high school biology, chemistry, and physics teachers in selected Texas high schools. The subproblem was to compare the emphasis placed on the practices as reported by the high school teachers with the emphasis as recommended by national science education specialists, teachers of biology, chemistry, and physics in selected Texas colleges and universities, and teachers of professional education courses in selected Texas colleges and universities.
