Linfield College began hosting an invitational high school forensics tournament in 1933. It is the oldest high school tournament sponsored by a college or university on the West Coast and one of the oldest in the country.
According to Roy Mahaffey, Linfield alum, long-time director of forensics and creator of the high school tournament, McMinnville College, the predecessor of Linfield College, began organized forensics activity in 1880, with elocutionary delcamation and debate appearing as early as the 1860s.
Craig Singletary joined the Linfield faculty in 1960 as professor of speech and Mahaffey's forensics assistant and became the director of forensics upon Mahaffey's retirement. Because of his contributions to the Linfield Foreniscs Program, the high school tournament was named in his honor when he retired in 1993. The name also honors Craig's wife, Nancy Singletary, who assisted with tournaments even after Craig's retirement.
