A major in archaeology requires courses in all of the subdisciplines. If you are interested in ancient and classical civilizations, the particular undergraduate major is not important.
However, it is advantageous to begin learning several ancient and modern languages. As a rule, historical archaeologists major in anthropology or history. You’ll need to have an undergraduate degree (B.A./B.S.) to work as a field archaeologist in the U.S. and to perform basic laboratory studies.
An M.A./M.S. would be enough to direct field crews and is sufficient for many government positions in archaeology. It is also sufficient to work in the private sector, to teach in a community college, and to work for some museums. An M.A./M.S. with a thesis and a year of field and laboratory experience is the minimum for certification by the Society of Professional Archeologists.
Nowadays, there are thirty-six colleges and universities that offer archaeology degree programs in the US. They offer both forensic archaeology and historical archaeology.
There are two levels of graduate training in archaeology. The first is an M.A. or M.S. degree. It usually takes about 1-2 years of course work beyond the B.A./B.S. degree and a written thesis which presents the results of original research by the student. There are also some programs that offer a non-thesis M.A. degree. If you are planning to work immediately on a Ph.D. degree, the preparation of a thesis is an important part of the educational process.
