Background: Many school health teacher preparation programs do not train teacher candidates in the use of online resources available through the Centers for Disease Control and Prevention (CDC). Some CDC resources, such as the School Health Index, could significantly improve the quality of school health programs. To address this, the CDC and the American Cancer Society collaborated to train school health faculty to integrate these resources into teacher preparation programs. Purpose: This study evaluated the effect of the Institutes for Higher Education Academy (IHEA), a professional conference intended to train school health faculty in the use of the CDC online resources and to facilitate resource integration into health teacher preparation. Methods: This mixed methods study had two data collection phases. The quantitative phase used an online survey to determine the number of changes made in participants' programs. All school health faculty members who attended an IHEA were recruited via e-mail to participate (N = 151). After three rounds of reminder e-mails, an acceptable participation rate was reached (68%). Descriptive statistics and inferential statistics (Pearson correlations) were used to analyze data. In the qualitative phase, all participants who completed the survey were recruited to complete a follow-up phone interview (n = 103).The interview was tailored to each participant based upon survey responses to elicit examples of program changes made as a result of IHEA attendance, as well as benefits and barriers to change. Fifty-four interviews were conducted and recorded, then transcribed and coded. An inter-rater coded 15% of the transcripts to ensure inter-rater reliability. Qualitative data were triangulated with participant survey data. Results: The majority of IHEA attendees surveyed made changes to their teacher preparation programs, and subsequently trained an estimated 2,800 pre-service school health educators to use the CDC online resources. Through participant outreach, more than 7,000 school health faculty and in-service K-12 health educators were also trained. Conclusions: IHEA is an effective and sustainable approach to improving the quality of K-12 school health education.
