Nancy Sanders Peterson, president of Peterson Tool Co., in Nashville, had a problem all too common today: many of her workers were short on math skills. But Peterson, whose company had more than $10 million in 1995 sales, couldn't send more than 10% of her staff back to high school. Instead, she took advantage of a state-funded training program. At no cost to Peterson, high school teachers visited the precision-tool company twice a week to teach math classes between workers' shifts. A few employees even got their General Education Diplomas (GEDs). Peterson's experience doesn't have to be unique. At least 47 states offer companies some form of vocational- or adult-education-training funds, according to a 1995 report by Steve Duscha Advisories, in Sacramento, Calif.
