The health of the students in a class is of vital importance to every teacher because of the relationship between health of the students and their performance in school. Especially is this true of the Physical Education instructor and coach, whose job it is to work with the students in physical activities. High school teachers assume that the students in the elementary school have been taught the correct health practices. Whether the student is practicing the habit taught is a question that few teachers can answer. The only basis the teacher has for his answer to this question is observation of appearance, the performance of the student, and occasionally, answers to questions. After five years of teaching health and physical education on the secondary level, the writer became very interested in finding out just what the health habits of the boys and girls of Stockton High School actually consisted of, how much of their instruction in the elementary schools had been retained, and how much instruction had been given and retained since entering the secondary level.
