All Level II entrants must earn a minimum of 60 credit hours of approved study that include the course work described below. Since students entering the program at Level II already hold a degree in architecture or environmental design, some of the requirements described below may have been met in advance. For such students, the curriculum may be modified by substitution of electives for courses previously taken at another university. The appropriate area coordinator and the Director of Graduate Studies must approve any petitions for substitutions in the degree plan. Students with deficiencies may be required to undertake additional course work.
