UM Policy on Student Residency Classification
The University of Maryland, like most public institutions of higher education, classifies students as "in-state" and "out-of-state" for various purposes, including assessing tuition. "In-state" tuition represents a significant financial subsidy toward the cost of education paid by the State of Maryland and the University.
The Board of Regents limits eligibility for "in-state" to a narrowly defined group of students. If all the elements in the definition of "in-state" are not met, the student will be classified as "out-of-state," unless an established exception in the policy exists.
