This study investigated the attitudes of principals toward the legitimacy of pre-service teacher preparation programs conducted wholly or almost wholly online. Random cluster sampling was utilized to select participants in Indiana, Kentucky, and Ohio. A total of 326 principals completed questionnaires. Principals expressed apprehension about teacher dispositions and the "social" aspects of teaching that may be compromised in an online program, as well as the general ethicality surrounding online courses. If principals are to ultimately acknowledge the legitimacy of online teacher preparation, the degree-granting institutions must address these concerns and actively seek the input of administrators in program design.
