There exists a dearth of literature on the content, research method and research design trends of dissertations in education. Within one large subfield of education (i.e. counsellor education), an online and full-text archive of dissertations has become available. This archive contains over 200 dissertations produced in Oregon State University's Counselling Academic Unit from 1947 to 2014. Research questions concerning decadal differences in content, research method and research design were examined empirically. No decadal differences were discovered in the three aforementioned areas. Reasons for these findings were discussed.
