The Non-Tenure Line ranks are:
Assistant Professor (Research)
Associate Professor (Research)
Associate Professor (Teaching)
Associate Professor (Performance) – use limited to appointments in the performing arts
Professor (Applied Research) – use limited to appointments at the Stanford Linear Accelerator Center (such appointments are always coterminous with continuation of contract support at SLAC)
Professor (Clinical) – use limited to the School of Medicine for appointments prior to 1989
In everyday usage, the parenthetical designation may be removed from the titles of Assistant Professors, Associate Professors and Professors holding Non-Tenure Line appointments, but it must remain in the titles in personnel files, CVs, appointment and promotion papers, administrative records and other similar documents.
