RICHMOND, AUG. 4 -- Virginia has failed to meet promised goals in desegregating its colleges and the U.S. Office of Civil Rights quietly acquiesced to the state's inaction, plaintiffs' lawyers have charged in an 18-year-old case.

The allegations filed with the federal agency in Washington came in response to an amended desegregation plan accepted in March by the agency.

"In almost every aspect of desegregation of student enrollment, Virginia is doing worse at the end than it was at the beginning of the {original} plan," according to documents.

In response, Gov. Gerald L. Baliles said that although some of the criticisms are valid, Virginia has made significant strides to carry out college desegregation agreements made with the agency.

Although their attack was largely directed at Virginia and four other states involved in the case, the lawyers did not spare the federal agency.

They accused the agency of "deceptive characterizations of state efforts. Despite the agency's disclaimers of not having reached conclusions" on state progress, "the reports are full of effusively laudatory . . . statements characterizing what states have done, even in the face of promised measures not undertaken or only half realized."

A major goal of the Virginia plan was closing the gap in the rates at which whites and blacks go to college. But that gap has "widened steadily and significantly since 1978," the lawyers argued.

State statistics show black students received 37 percent of available financial aid in 1978 versus 26.5 percent by 1985. And black students got "significantly less than . . . whites in each of the last two years of the plan" that expired in June 1986.

The dispute, known as the Adams case, is believed to be headed for another review by U.S. District Judge John H. Pratt of the District of Columbia. Pratt has threatened states in the case with unspecified penalties if they cannot prove "substantial progress" was made under their desegregation plans.
