The U.S. Civil Rights Commission said yesterday Fairfax County has succeeded in its efforts to integrate the public schools, but said Baltimore remains entangled in litigation, with 60 percent of its minority students still in all-black schools.

Part of the difference, the commission's latest status report noted, is that 91 percent of Fairfax County students are white. "Another factor is the absence [in Fairfax] of community groups actively opposing desegregation," the study said. It praised the county's personnel training program, its department of human relations, established in 1971, and its efforts to hire minorities and women in administrative jobs.

"There appears to have been no significant increase in white student movement to avoid desegragation," the report said.

In Baltimore, the schools were 76 percent nonwhite in 1977, while teachers and administrators were 63 percent minority, higher percentages than in 1971. Fully 86 percent of all suspensions involved nonwhites, compared to 91 percent in 1975. Such numbers often indicate discrimination, the report said.

"The legal status of school desegregation in Baltimore has not been resolved," the study said.The Department of Health, Education and Welfare found the schools in violation of the 1964 Civil Rights Act in 1975, and court battles have continued since then over HEW's announced intention to cut off funding to the school system.

Maryland has asked for a permanent injunction against any move to cut the funding, while HEW is expected to appeal any such order.
