About 300 high school students who were promised a free college education by Ewing Kauffman, co-owner of the Kansas City Royals, have another incentive to do well in school.

Michael Herman, president of the Kauffman Foundation, announced that members of a freshman class who are enrolled in the college program, called Project Choice, will receive $50 a semester for attending classes regularly at Westport High School.

"If you're not in school, then you can't become an academic success," Herman told several hundred students and their parents.

Project Choice, started last spring and administered through the foundation, guarantees a college education for members of last year's eighth-grade class at Westport Middle School who meet certain requirements.
