This indicator of the month summarizes data from the National Center for Education Statistics School and Staffing Survey, 1993-94 (Teacher Questionnaire) regarding teacher participation in professional development (including seminars offered by schools or school districts and courses affiliated with institutions of higher education). Some findings are: (1) over 50 percent of public school teachers participated in professional development; (2) full-time public school teachers were more likely to participate in activities of all types of professional development topics than were full-time private school teachers, and elementary school teachers more than secondary teachers; (3) 48 percent of public school teachers received released time from teaching, and 41 percent received scheduled time for professional development; (4) public school teachers were more likely to receive professional growth credits and released or scheduled time from teaching than were their private school counterparts; however, private school teachers were more likely to receive tuition and/or fees; and (5) public elementary and secondary school teachers in their first three years of teaching were more likely to have participated in a formal teacher induction program than were teachers with four or more years of experience. A table and two figures are included. (ND)
