Brief Summary:
The investigators propose an efficacy study (i.e., do salad bars work under controlled conditions in naturalistic settings) to test whether introducing salad bars in elementary, middle, and high schools that have never had salad bars affects students' FV consumption and waste during lunch. A cluster randomized controlled trial will test new salad bars against controls for 6 wks, with/without an additional 4-wk marketing phase .
