This report was prepared by the Texas Education Agency in response to Section 39.183 of the Texas Education Code. In a phase-in approach written into law, the limit of 22 students to 1 teacher applied in the 1985-86 school year through the 1987-88 school year to kindergarten through grade 2 only. The law extended this limitation to kindergarten through grade 4 beginning with the 1988-89 school year. The commissioner of education may grant class-size waivers only in cases where districts are unable to employ qualified teachers, where districts are unable to provide educational facilities, or where the 22:1 class-size ratio is exceeded in kindergarten through grade 4 in districts that budgeted for that particular class-size. Waivers cannot be granted if they relate to essential knowledge or skills, minimum graduation requirements, removal of a disruptive student from the classroom, at-risk programs, or requirements imposed by federal law or rule. By law, waivers can be granted for only one semester at a time. Summary information on regional education service centers includes a brief history, staffing levels, financial positions, programs and services, and regional performance levels. Charts and graphs serve to illustrate textual data. A map showing Regional Education Service centers is also provided. (RT)
