Summary.— A questionnaire was given to 102 male training college students followed by an interview at which fifteen main questions were put. Evidence was obtained suggesting that: The subjects (excluding crafts) which male students read at training college are those which they enjoyed most, or felt they did best in, during the latter years of the grammar school course. There is a significant association between the clearly displayed interests of the parents and the subjects which the son prefers to study later on. There is a significant association between studying science subjects at a training college and attitude to, or performance in, arithmetic in the junior school. The influence of the immediate environment, and of the scientific atmosphere in which our interviewees had been reared, does not seem to be of much consequence in affecting their choice of subjects. A number of suggestions are briefly outlined arising out of our evidence and from a study of wider issues.
