Requirements for recommendations:
Two recommendation forms must be from faculty members of the undergraduate major department or professionals in the field who can evaluate the scholarly achievement and potential of the applicant. These recommendations form an important part of the admission credentials.
Applicants must submit official scores from the Graduate Record Examination (GRE) if they graduated from an institution not accredited by a regional accrediting agency of the USA. The Department of Engineering may choose to waive the GRE requirement if at least one of the following special circumstances is met:
Applicant's last degree is from a U.S. institution accredited by a regional accrediting agency.
Applicant's overall GPA from last degree is at least 3.0 on a 4.0 scale.
Applicant has worked in the USA for at least two years in the engineering profession.

You must submit transcripts from all colleges/universities you have attended. If your last degree was obtained from an international college/university, your transcripts must be evaluated by a professional credential evaluation service.

Oakland University will only accept transcript evaluations completed by a current member of NACES. Most students choose World Educational Services, Educational Credential Evaluators or SpanTran. Graduate programs usually require a course-by-course (or detailed) evaluation report rather than the general evaluation report. Since official transcripts are required for your transcript evaluation.
