An exploratory evaluation of the effect of a multicomponent nutrition education program on student knowledge and behavior change is described. The nutrition education program was implemented in an urban environment with African American children and their families. Results of the outcome evaluation indicated the program was implemented with generally acceptable integrity and was considered socially valid from the perspective of teachers and students. There were robust increases in knowledge related to healthy eating among students who received nutrition education in this program relative to baseline and to students in the control group. Changes in eating behaviors were not statistically significant. Roles for school psychologists interested in implementing and evaluating health promotion programs are discussed.
