Since 1983, Congress has increased funding to allocate an increasing number of staff-years specifically for AIDS programs. By 1988, about 40 percent of AIDS staff-years were allocated pursuant to specific congressional directives and the remaining 60 percent were reallocated from other programs. CDC officials report that allocating staff to AIDS programs has had less effect on meeting existing programs' missions than on the agency's ability to start and expand programs. However, CDC does not account for actual staff time spent by program or activity. As a result, the agency cannot easily determine and document staffing needs for its diverse activities. It is recommended that CDC staff develop better management information so that the agency and the Congress can make more fully informed staff allocation decisions. Appendix.
