As speculation mounted about the future of top officials at the University of the District of Columbia, UDC Vice President Dwight S. Cropp said yesterday he has received job offers outside the university and is considering leaving his post.

Cropp, a former secretary to the District who was appointed UDC vice president for resource management and development by then-President Robert L. Green, said he will make a decision soon about two job possibilities -- one in the private sector and one in government.

Cropp is one of 12 UDC administrators who hold so-called "excepted service appointments" given to them by Green, who resigned under pressure after disclosures of questionable expenditures of university funds.

The future of other top administrators in excepted service, who serve at the pleasure of the university president, remains unclear. However, a UDC trustee said yesterday that "there is a plan afoot to have them out within 60 days" of Green's resignation, which was submitted Aug. 23.

The trustee, who asked not to be identified, said some of the administrators would be removed while others would be reassigned to other posts at the District's public land-grant university. "We have so much baggage coming along with these people that we have to clean house," the trustee said. "It would be a problem if the president goes and these people stay."

Board Chairman N. Joyce Payne said the 12 administrators serve at the discretion of Claude Ford, the interim president. "Consequently, one anticipates that . . . it would be left to the discretion of Mr. Ford," Payne said.

Ford said yesterday he had not made a decision about the Green appointees.

Among the 12 administrators are five who worked under Cropp in the office of the D.C. secretary and then moved with him to UDC. Also included is Maxie Jackson, the provost and vice president for academic affairs who was a close associate of Green's at Michigan State University, where Green was a dean before going to UDC in 1983.

Three other close associates of Green, who were not excepted employes, were demoted or dismissed in a budget-related action Monday.

W. Louis Stone, who had been promoted to a temporary position of acting assistant vice president for resource management, was one of about 40 UDC employes who lost their temporary positions in a cost-cutting measure that came in response to budgetary cutbacks and a shortfall in tuition revenues, Ford said. Stone will remain at UDC as deputy budget director, the job for which he was originally hired in July 1984.

Gilbert A. Maddox, the operational research analyst who served as Green's spokesman throughout most of the controversy, lost his job in the cost-cutting move, as did Chester A. Higgins, a public information specialist.

The status of the excepted service appointees appears to be a potential sticking point among UDC trustees and administrators charged with putting the Green controversy behind the troubled institution.

Although Payne said the appointees' fates rest with Ford, several trustees have made clear they want them out. Joseph Webb, the outspoken trustee who was the first to call for Green's resignation, said yesterday the appointees "ought to go."

Trustee Herbert Reid Sr., who also serves as legal counsel to Mayor Marion Barry, said there could be legal consequences if trustees pressure Ford to oust the appointees.

"I hope they are not creating such pressure on him that he is not able to exercise his own free will," Reid said. "If these matters are challenged in court, it will be important whether or not it was his will or whether it was generated by the board."
