How to become an archivist
Get a master's degree in library science (mlis).
An mlis is the most common educational requirement for becoming an archivist. The best mlis programs will have a curriculum enriched by courses in record keeping, archival administration, and born-digital documents that can familiarize you with archival processes and practice.
Mlis courses will offer training in both libraries and archives. Most mlis programs focus more on libraries than on archives, but tend to balance in the other direction.
