* Missionaries: Especially in colonial and frontier settings, missionaries often took on the role of educators, combining religious instruction with basic literacy and other skills.
* Military personnel: In military schools or schools established near military bases, officers or enlisted personnel might serve as teachers, particularly for basic subjects.
* Government employees: Depending on the specific bureau, government employees assigned to educational duties, possibly with some basic training, would teach.
* Local community members: In some instances, especially in sparsely populated areas, individuals with some level of literacy or education from the local community might be employed as teachers. These individuals often had limited formal training.
It's important to note that the quality and training of teachers in bureau schools varied greatly depending on location, time period, and the resources available to the sponsoring agency. In many cases, teachers lacked formal pedagogical training and their instruction was often rudimentary.
