Faculty receiving summer salaries are paid at a rate of one-ninth of the academic-year salary per month. Such appointments do not normally exceed two months' duration. University policy permits the payment of summer salary for up to two and a half months, provided that any salary beyond two months is derived from outside sources (4000, 6000 accounts). Requests for summer salary beyond two months must include a statement that no vacation will be taken during this time. Summer salary payments are made at the end of July and at the end of August. Summer employment must be authorized each year, in advance, through procedures established by the Dean of the Faculty.
