Utah's K-12 class sizes are the highest in the nation, a University of Utah report found earlier this year. Utah's ratio is 22.4 students to one teacher compared to the national average of 15.4 students to one teacher. Jeffrey Keller, father of a student at Farmington Elementary with a class size of 37, talks with D2 about this issue from a parent's perspective. Listeners are invited to call in about their experiences with large class sizes.
