This guide (which updates an earlier publication) provides information on Ohio's requirements for licensing for major occupational and professional groups. Based on a survey of state licensing agencies, the report is divided into two sections. Section I summarizes the information provided by the agencies on their requirements. The information is organized by agency and specifies the occupations and professions licensed by each. For every occupation listed, information is included on basic legal and educational requirements for licensure and relicensure, and other licensing data. Section II outlines the continuing education requirements for the agencies surveyed that have such requirements. An appendix contains a chart listing requirements by state for continuing professional education in 16 fields. Two indexes are in included in the report. Index I is an alphabetical listing of the occupations and professions included in this survey. Index II lists the state licensing boards and agencies that oversee those areas. (KC)
