Admission Requirements Exceptions

If you do not meet all the requirement criteria for admissions, you may still be admitted to a program. Admission in these cases is determined on a case-by-case basis. These candidates may be granted provisional status.

Provisional Student

Provisional students are admitted to this status because, in the view of the admissions committee, they do not fulfill academic requirements for admission as a degree candidate at the time of the application. Provisional students may be required to take specific prerequisite courses, and/or take a specific number of courses and complete them successfully in order to establish their eligibility to be admitted as a degree candidate.

During the time of this provisional status, students are held to grading criteria stricter than those required of degree candi­dates. Specifics of a provisional admission are outlined in a formal admissions letter mailed to the student. All listed criteria must be met for a student to continue to enroll in courses.

Math Test

Provisional students who are required to take 420.301 Quantitative Methods for Environmental Sciences, may choose to take a mathematics assessment test. If successfully passed, provisional students will place out of the prerequisite. This test is administered on the Baltimore campus and at the Washington, DC Center at the student’s convenience any working day. After a student is admitted, s/he may make an appointment to take the test and/or to obtain relevant study materials by calling the Admissions Office in Washington at 202-452-1940.

If you have a question about admission requirements, please contact admissions.
