School administrators in Alexandria and Fairfax counties this week finished investigating allegations of sports recruiting violations in the two school systems and will make their report within two weeks, school officials said yesterday.

Thomas M. LoFaro, a member of the three-man team appointed to conduct the investigation, said its findings will be presented to the superintendents of the school systems. LoFaro declined to comment further.

The investigation reportedly was prompted by complaints of students from T. C. Williams High School in Alexandria against the coaching staff at Mount Vernon High School in Fairfax County. The complaints alleged that coaches at Mount Vernon attempted to recruit athletes away from Williams and other high schools, a practice prohibited by the Virginia High School League.

School officials said the two-month investigation has expanded beyond those two schools.

Fairfax School Board member Gerald A. Fill, who represents the Mount Vernon area, said the investigation "smacks of bureaucratic politics" and is based on allegations that were "unwarranted and not well founded." He said investigators reportedly have examined cases that date back 10 years.

The president of the Mount Vernon Parent-Teacher-Student Association accused county officials of harassing the school.

"When a school has a successful sports program, that school is often harassed," said Linda P. Pendergraph. "They (Mount Vernon coaches) have never been found guilty of any improper conduct."

The investigative team, composed of a representative from Alexandria and Fairfax counties and a neutral representative from Prince William County, was appointed by the superintendents of the Alexandria and Fairfax school systems.
