The maximum number of pupils per teacher shall be determined by the board of directors of the local district or the area education agency board in accordance with the rules and regulations of the state board of education.3. The board of directors of the local district or the area education agency may establish and operate one or more special education centers to provide diagnostic, therapeutic, corrective, and other services, on a more comprehensive, expert, economical, and efficient basis than can be reasonably provided by a single school district. The services, if offered by the area education agency board, may be provided in the regular schools using personnel and equipment of the area education agency or, if it is impractical or inefficient to provide them on the premises of a regular school, the area education agency may provide services in its own facilities. To the maximum extent feasible, centers shall be established at and in conjunction with, or in close proximity to, one or more elementary and secondary schools. Local districts or the area education agencies may accept diagnostic and evaluation studies conducted by other individuals, hospitals, or centers, if determined to be competent. Children requiring special education services may be identified in any way that the department of education determines to be reliable. Centers established pursuant to this section may contain classrooms and other educational facilities and equipment to supplement instruction and other services to children with disabilities in the regular schools, and to provide separate instruction to children whose degree or type of educational disability makes it impractical or inappropriate for them to participate in classes with normal children.
