Part 1 of the 1962-63 Education Directory of the Office of Education covers state governments. The principal school officers of state and territorial education departments and library extension agencies' executive officers are listed in order to enable officials' identification and illustrate organizational structure and hierarchy. The chief state and territorial officers provided their departmental information and verified it at the beginning of the school year. The Office of Education asked the chief school officers to include all regularly employed personnel with statewide duties who report directly or through a superior to the chief state school officer. Field or regional personnel under supervision of a department officer other than the chief state school officer are excluded. All personnel with state-operated schools, libraries, museums, radio stations, etc. that are administered through the state education department are excluded. The U.S. Office of Education Library Services Branch supplied the information for the library extension agencies. Part 2 provides a directory of public school systems by state and includes a supplement on church-related schools. Two types of administrative units are included: intermediate administrative units and local school systems enrolling 300 or more pupils. Data came from the most recent state education directories, a Bureau of the Census listing as of October 1961, and a recent "School Management" magazine list. State education departments verified their information. Superintendents or their counterparts are listed by state for the five religious organizations maintaining state, regional, or national school systems. Part 3 provides higher education enrollment data and lists by state institutions of higher education offering at least a two-year program of college-level residential study. Criteria for listing and institutional classifications are given. Part 4 lists national and regional education associations; college professional fraternities, and national honor and recognition societies; state education associations; foundations; religious education associations; and international education associations. Part 5 provides directories of the U.S. Department of Health, Education, and Welfare Office of Education, executive departments, independent agencies, the Organization of American States as a multilateral international organization, and the American National Red Cross and the National Academy of Sciences as quasi-official agencies.
