Prince George's County officials, citing budget constraints and a sagging local economy, said yesterday that a new set of recommendations to bolster black male achievement may be too costly to implement.

The recommendations, contained in a report issued this week by a group of business, school and religious leaders, said black males are represented disproportionately in special education classes, among school dropouts and among those who are suspended from school.

But school officials and county politicians said there is no available money to implement the committee's recommendations, which would cost upward of $125 million.

School officials said the county's current $561 million education budget barely covers operating costs and new programs cannot be created without weakening existing ones. And county officials said they cannot increase school spending without chipping away at funding for law enforcement, road improvements or other county services.

To make matters worse, state funding for Prince George's County, among the five most affluent jurisdictions in Maryland, is not likely to increase at a time when state legislators are weighing measures to increase school spending in less-prosperous school districts.

"The fact is that excellence comes at a cost," said School Superintendent John A. Murphy. "And the citizens of Prince George's County are going to have to decide what they want. If excellence in education is what they want, then they are going to have to pay for it."

Murphy has publicly encouraged residents and privately solicited business leaders to pressure county officials to repeal or amend TRIM (Tax Reform Initiative by Marylanders), an amendment to the county charter that put a limit on property taxes and severely limited county spending.

But county politicians have preferred not to discuss taxes, particularly in an election year. County Executive Parris N. Glendening said he would not support a drive to repeal or amend TRIM.

"We are going to have to sit down and see if we can achieve a consensus between state and local leaders to come up with some answers," Glendening said. "Right now I do not have the answers. I don't think anyone does."

The county spends 44 percent of its $998.6 million budget on education, according to the report. The study noted that the percentage of education spending had decreased by 10 percent since 1979, while the school system's black student enrollment had increased by 17 percent during the same period.

Members of the advisory committee did not suggest specific options for generating school funds, and explained that their role was to arm the public with information that might amplify the debate about school funding.

"What you have here is a situation where everybody agrees that we have a problem -- a very, very serious problem -- but no one wants to come up with money to solve it," said Wayne K. Curry, chairman of the Superintendent's Advisory Committee on Black Male Achievement and chairman of the county Chamber of Commerce.

Some residents seem to be motivated by the report, however.

"I have never been politically inclined, but when I see statistics showing that the average black {male} student has a D+ grade point average and that only 44 black males in the entire school system are taking calculus . . . that made me realize that I have a moral imperative to get involved in this debate before we lose another generation of black boys," said Carolyn Davis, a Landover Heights resident who attended a news conference yesterday where the report's findings were released.

One of the committee's primary and most expensive recommendations called for providing all schools with the resources afforded the so-called Milliken II schools, which receive special funding and additional staffing under the school system's desegregation plan. The Milliken II program is limited to predominantly black schools inside the Capital Beltway that are so far from white neighborhoods as to be difficult to integrate.

Expanding the Milliken II program, which includes decreased class sizes, additional support staff and enhanced computer and library resources, would cost at least $100 million, school officials said.

The call for "Millikenizing" more schools coincides with mounting community tension over the disparities in funding between general neighborhood schools and the special magnet and Milliken II programs.

The advisory committee's report included statistics showing that the school system spends $5,267 per pupil at Milliken schools, $5,093 at magnet schools and $4,578 at general neighborhood schools.

Of the county's 105,595 students, 17.5 percent are enrolled in magnet schools, 9 percent are in Milliken schools and 73.5 percent attend general neighborhood schools.

The advisory committee's report warned that such disparities would lead to "a community polarized by race, social class, geographic location and by the type of school program one's child attends . . . . County residents must work to guarantee that all schools receive sufficient support."
