Sustaining school-based asthma programs is critical due to the large population affected and because of the considerable health knowledge and behavior change that must occur for symptoms to improve.15 Goodman et al16 outlined the need for sustainable programs, including their ability to deliver both complex behavior change and cultural shifts, and the fact that the ending of programs is costly for the organization and the staff employed by them. Sustaining programs over time reinforces education and training, provides opportunities to reach more individuals, helps to reinforce the behavior change necessary to make longlasting positive effects on health outcomes, and results in improvements in asthma care management.17
