Some individuals enjoy taking seminary classes only on a periodic basis, perhaps because of continuing education interests or personal constraints. Some ESR residential and ESR Access courses are open to these individuals. Persons interested in this option apply for admission and register through ESR's Occasional Student program, either as an Occasional or ESR Access Occasional student. A fee of $35 a year is required to maintain Occasional Student status. Students may take any course at the 100 or 200 level. Students with the appropriate background may take 300 level courses, with the permission of the instructor. Occasional students may take up to two courses per semester.
