Museum internships are one of the core courses in museology and museum studies; they are required in the curriculum for relative graduate and postgraduate programs. It is also an important part for the talent development of museum professionals. In fact, museum internships are relevant to universities, students and museums. Most of the research on museum internships focus on the curriculum arrangement, the experience of interns. However, seldom has it been discussed from the perspective of museum practice. In this paper, the author would like to investigate the Summer Internship Program at the National Museum of History both from the planning and the practice aspects. On the basis of the museum practice perspective, this essay will propose to rethink the theory and practice of museum internships, and to suggest some ways to improve the internships program.
