This report provides an overview of educator supply and demand, educator under/oversupply, projected areas of greatest demand and need, and information regarding retirement of teachers in Illinois. Major findings include the following: there appears to be a sufficient number of qualified teachers, yet there are still a number of unfilled positions that vary dramatically among regions. The population of Illinois teachers is aging, and the projected number of teachers reaching retirement age is expected to double over the next 5 years. In terms of number of jobs, the top four projected areas of high demand in Chicago are self-contained classrooms, Title I remedial reading, learning disabled, and cross-categorical. The top five projected areas of high demand for downstate school districts are self-contained classrooms, learning disabled, behavior disordered, speech and language impaired, and physical education. When the reserve pool is taken into consideration, undersupply for specifically trained teachers exists in early childhood special education, gifted education, and languages other than English. An oversupply of educators exists in self-contained classrooms and social science. Appendices list educational personnel by main position, 1998-99 supply by teaching assignment, and 1998-99 supply and demand by teaching assignment. (DFR)
