The Northern Virginia Criminal Justice Academy wants to move its training program for law enforcement officials from Fairfax City to Arlington's Claremont Elementary School, scheduled to close this week.

Larry J. Brown, Arlington's county manager and chairman of the academy, said yesterday that the academy hopes to begin negotiations this week with the County School Board, which is retaining ownership of the school, for a seven- to 10-year lease.

The academy trains about 360 police officers and deputy sheriffs annually from all Northern Virginia localities and provides brush-up training for 825 police officers and 146 deputy sheriffs each year, Arlington Police Chief William K. Stover said.

The academy leases an old and deteriorating grade school at 10201 Main St. in Fairfax City for $1 a year and hopes it will be able to lease Claremont for the same amount while it looks for permanent quarters, Brown said. Preliminary estimates are that it would cost between $7.6 million and $9.7 million to build a new facility.

Brown said the academy would maintain Claremont in the same or improved condition, at no cost to the school board, and would not schedule any outdoor firearms or driver training.
