The supervision is frequently undertaken by the teachers. In 1909, the Board of Education reports that the "assistance of teachers has been the rule rather than the exception."[277] This service is always rendered voluntarily, though occasionally, as at Bradford, the teachers receive some small remuneration.[278] The amount of service given varies widely in different towns. At Bradford the same teacher will attend the centre daily for months. In other towns his or her turn may come quite infrequently, and may only amount to two or three days' service at a time.[279] Sometimes School Managers, members of the Canteen Committee or voluntary workers take it in turn to assist in the supervision, but their attendance is generally spasmodic. At Portsmouth the centres are entirely in charge of ladies who give their services voluntarily.[280] As a rule, however, paid superintendents are appointed, too often women of the caretaker type. In some towns the School Attendance Officer attends to collect the tickets and helps to maintain order.

Footnote 278: The head teachers receive 5s. a week for supervising dinners, and 2s. 6d. for breakfasts; the assistant teachers 4s. and 2s. respectively. At Derby also the teachers are paid. (Report of the School Medical Officer for Derby, 1911, p. 61.) This payment is very exceptional. Footnote 279: At Leeds, for instance, the teacher will perhaps be called on for a day or two every two months. At Liverpool a teacher is supposed to attend once a fortnight, but often no teacher at all is present. At Bootle the turn may be one day a week or a fortnight, or perhaps a week at a time; here the teachers, we were informed, voluntarily give their services "under protest," a fact which, when one considers the conditions under which they are asked to serve the meals, is not surprising.
