This report presents the administrative procedures adopted by the Board of Governors of the California Community Colleges in March 1983 to standardize the calculation of noninstructional costs supported from revenues generated by average daily attendance (ADA) in special classes for disabled students. First, background information is provided, indicating that Handicapped Student Programs and Services (HSPS) are presently supported by Direct Excess Cost (DEC) funds, which are allocated to districts to meet the additional expenses incurred as a result of providing specialized instruction and support. Information is also presented on the types of services financed by DEC funds, disabled student enrollments, and controversies surroundng HSPS. Next, three related problems in HSPS funding are addressed: (1) the employment of differing procedures for calculating cost rates by individual districts; (2) the lack of a precise definition of reasonable general fund support for special assistance programs; and (3) the nonapplicability of the same cost rate computations for both on- and off-campus programs. Finally, procedures for the equitable determination of noninstructional cost rates are presented, including definitions of on- and off-campus special classes and programs, and information on computing noninstructional cost rate and determining the amount of general fund monies that must be utilized before DEC funds can be claimed.
