The advantages of physical examination upon beginning and during the courses that prepare one for a teacher are so obvious that but little opposition will be given by prospective teachers. The disadvantages to teacher and pupil alike of suffering from physical defects are so obvious that every school which prepares men and women for teachers should make registration and certification dependent upon passing a satisfactory physical test. No school should engage a teacher who has not good proof that she can do the required work without injury to her own or her pupils' health. Long before physicians can discover pulmonary tuberculosis they can find depleted vitality which invites this disease. Headaches due to eye trouble, undernourishment due to mouth breathing, preventable indigestion, are insidious enemies that cannot escape the physical test. Three objections to physical tests for teachers will be urged, but each loses its force when considered in the light of general experience. 1. _A sickly teacher is often the most efficient teacher in a school or a county._ It is true that some sickly teachers exert a powerful influence over their pupils, but in most instances their influence and their efficiency are due to powers that exist in spite of devitalizing elements. Rarely does sickness itself bring power. It must be admitted that many a man is teaching who would be practicing law had his health permitted it. Many a woman's soul is shorn of its self-consciousness by suffering. But even in these exceptional instances it is probable that children are paying too dearly for benefits directly or indirectly traceable to defects that physical tests would exclude. 2. _There are not enough healthy candidates to supply our schools._ This is begging the question. In fact, no one knows it is true. On the contrary, it is probable that the teacher's opportunity will make even a stronger appeal to competent men and women after physical soundness and vitality are made conditions of teaching,--after we all believe what leading educators now believe, that the highest fulfillment of human possibilities requires a normal, sound body, abounding in vitality. 3. _Examination by a physician, especially if a social acquaintance, is an unnecessary embarrassment._ The false modesty that makes physical examination unwelcome to many adults, men as well as women, is easily overcome when the advantages of such examination are understood. It is likewise easy to prove to a teacher that the loss of time required in having the examination is infinitesimal compared with the loss of time due to ignoring physical needs. The programme for school hygiene outlined in Chapter XXVII, Part IV, assumes that state and county superintendents will provide for the examination of teachers as well as of pupils.
