INFORMATION ON STATE CERTIFICATION OF TEACHERS IN CATHOLIC SCHOOLS, THE LARGEST SECTOR OF THE NONPUBLIC SCHOOLS, WAS PROVIDED BY A SURVEY OF (1) STATE POLICIES FOR CERTIFYING CATHOLIC SCHOOL TEACHERS, (2) THE EXTENT OF STATE CERTIFICATION IN CATHOLIC SCHOOLS AND REASONS FOR THESE SCHOOLS' CERTIFICATION STATUS, AND (3) OPINIONS OF DIOCESAN SUPERINTENDENTS OF SCHOOLS ON THE SUBJECT. SEPARATE INSTRUMENTS WERE DIRECTED TO THE CHIEF CERTIFICATION OFFICER IN EACH OF THE 50 STATES, A STRATIFIED RANDOM SAMPLING OF TEACHERS IN CATHOLIC ELEMENTARY AND SECONDARY SCHOOLS, AND THE DIOCESAN SUPERINTENDENT OF EACH DIOCESE WITHIN 50 STATES. DATA OBTAINED FROM THESE GROUPS FORMED THE BASIS OF THE STUDY. THE INSTRUMENTS USED WITH THE GROUPS WERE A QUESTIONNAIRE, A CENSUS FORM, AND AN OPINIONNAIRE, RESPECTIVELY. FINDINGS PRESENTED THE AMOUNT OF INTEREST ON THE CENTRAL TOPIC AMONG THE RELEVANT GROUPS, THE AMOUNT OF COOPERATION BETWEEN DIOCESAN AND STATE EDUCATIONAL LEADERS IN THE PLANNING OF CERTIFICATION PROGRAMS, AND THE ACCEPTANCE OF STANDARD STATE CERTIFICATION AS A PREREQUISITE FOR EMPLOYMENT IN CATHOLIC SCHOOLS.
