Archivists decide what parts of information produced by government, schools, etc. should be made part of the historical record. At least a master's degree is required for employment in archival management. Related studies may be in the areas of records management or library studies. In order to teach history in the public schools, in most cases you will be required to be certified to teach social studies.
