*The Loudoun County school census, slated to end tomorrow, has been extended to June 6 to ensure that all eligible persons are counted. The schools' planning director, Gordon Fletcher, said more time was needed because of poor weather and the large number of households in which both parents work during the day.

All county children from ages 1 through 19 and all handicapped persons through age 21 must be counted to ensure that Loudoun receives its share of state education funds. Over the next three years the county will receive about $900 for every person counted, Fletcher said.

The 30 part-time workers trained to make the house-to-house count will wear identification badges and will carry introductory letters from School Superintendent Robert Butt.

*Broad Run High School senior Paul LeBeau is Loudoun's first winner of the Virginia Scholars Program award, which provides as much as $12,000 in financial aid over four years at a state-supported college or university. LeBeau, who has also won a National Merit Scholarship award and has been named a Rodman Scholar by the University of Virginia, plans to enter U-Va. in the fall. The $3,000 awards are renewable if winning students maintain a B or higher, or if they rank in the top quarter of their classes.

School spokeswoman Molly Converse said this year's Virginia Scholars were selected from nearly 1,000 nominees attending more than 300 public and private high schools across the state. The 45 winners rank in the 98th percentile of their graduating classes.
