For those Faculty receiving summer salaries, 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 and ordinarily include payments from sponsored research funding. University policy does permit the payment of summer salaries for up to 2.5 months, provided that any salary beyond two months is derived from outside sources. 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.
