In fall 1984, about 3.9 million full-time equivalent (FTE) staff personnel were employed in public elementary and secondary schools in the 50 states and the District of Columbia. This is a decrease of 0.4 percent, or about 1,600 employees, from FTE staff employed in fall 1983. This bulletin gives the number of staff in FTE's and reports the data on staff assignments in two categories: instructional staff (teachers and instructional aides) and support services staff (local education agency (LEA) officials and administrators, guidance counselors, librarians, and all other support services staff). The bulletin includes definitions of the following staff assignments: instructional (teacher) aides, officials and administrators, guidance counselors/directors, librarians, school administrative support staff, and all other support services staff. Five tables cover the following topics: states with an increase and states with a decrease in number of teachers, fall 1983 to fall 1984; the number and percent of staff employed by public school systems, by type of staff and by state, for 50 states and the District of Columbia in fall 1984 and in fall 1983; and the number and percent of change in staff employed by public school systems, by type of staff and by state, for 50 states and the District of Columbia in fall 1984.
