Art history students are encouraged to do internships at New York area museums and other non-profit institutions. Interning at galleries and auction houses is legal if it offers compensation of at least minimum wage. Majors who lack 2 credits in Art History and who wish to secure unpaid internships in art galleries or other for-profit art related organizations may instead apply for an independent study (2 credits maximum) subject to adviser approval. It should be noted that approval is granted on a case-by-case basis; it is not guaranteed. Independent studies typically require the completion of a 20-page paper. Students must also provide the professor with a letter from their supervisor at work, confirming their participation and performance.
