From The Lexington Herald-Leader: Enrollment in Fayette County (Ky.) Public Schools continues to grow by several hundred students or more annually. This year, enrollment is up 2 percent, to 37,365 The rapid expansion has left school administrators weighing whether to spend money on buildings or on services and has left students with crowded conditions at several schools. Henry Clay High School in Lexington has more than 2,200 students and is using portable classrooms to help absorb the load. Some high schools are adding lunch periods or having teachers "float;" that is, to use another teacher's classroom when it is unoccupied. Some elementary schools also rely on portables.
