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 granted for a minimum of one term to one year, renewable each year up to a maximum of three years.
