Special Students are visiting students who are currently enrolled in a graduate degree program elsewhere and require academic transfer credit from Caltech, and/or who will be paid a stipend through the Caltech payroll system. Special students are eligible for Caltech benefits as defined by their enrollment status. Special Students who receive a stipend will be billed for tuition and fees and tuition remission will apply for any student paid on a grant. Special students who do not receive a Caltech stipend will be billed the minimum tuition and fees rate (rates vary each year, but are the equivalent to three units of tuition). Special student appointments are allowed for one year, renewable each year up to a maximum of three years.
