The Department of Agricultural and Extension Educa- tion offers major work for the degrees of Master of Science (thesis) and Master of Agriculture (nonthesis) (see Require- ments for Master's Degrees). Two curriculum options for graduate study toward either degree are offered. The extension option is for those persons currently employed or preparing to be employed in the cooperative extension service, including home economics, agriculture, 4-H, and other related areas. The teaching option is for persons who are teaching voca- tional agriculture in the public schools and those who wish to enter the profession and require basic certifica- tion. A prospective graduate student need not have majored in agricultural and extension education as an undergradu- ate. However, students with an insufficient background in either agricultural and extension education or technical agriculture will need to include some basic courses in these areas in their program. The Department of Home Economics offers graduate students with home economics related interests the op- portunity for field experience and research activity in the areas of family and consumer economics, housing, and foods and nutrition.
