The results of a questionnaire sent to 443 teacher education institutions, listed in the 1965-66 report of the National Council for Accreditation of Teacher Education, are reported in this document. Responses to the questionnaire, which elicited information about campus curriculum laboratories or equivalents, revealed that the laboratories (found in 98 percent of 331 responding institutions) are controlled by the department or school of education, by the library, or jointly by both; that staff numbers, service hours, and holdings (books, periodicals, audiovisual and numerous other materials) vary among institutions; that over 70 percent do not consider their facility a branch library and do not use the Dewey classification system; and that 62 percent process their materials in the curriculum laboratory. The responses are also evaluated according to whether or not they indicate an understanding of the purposes and function of a curriculum laboratory, defined as a place where preservice and inservice teachers are exposed to an assortment of materials for the purpose of experimentation, evaluation, and enrichment of teaching and learning. A manual for preparing materials for the curriculum laboratory, a 47-item bibliography of related readings, a resource list, and purchasing guide are appended. (LP)
