ence and by personal visitation they learn what schools and colleges are doing and attempting to do. Similarly the Bureau seeks first-hand knowledge of registrants’ qualifications through interviews and by study of the records and confidential ap- praisals of registrants. What success do Bureau registrants achieve in their positions? What are their failures, their points of strength? Teachers College and its Bureau of Edu- cational Service are effective only in so far as the men and women who take courses at the College are successful as teachers and school executives. The Bureau, therefore, after registrants have been in new positions for a reasonable period, asks employers for evaluations of their work. Criticism of and suggestions for im- provement of Bureau service are invited from employers, registrants, and faculty members. Only on the basis of frank criticism can the Bureau improve its service. It desires to be fair, honest, and helpful in its contacts with every em- ployer and every registrant. 7
