The MAE department engineering offers accredited programs leading to B.S. degrees in

• Bachelor of Science in Aerospace Engineering
• Bachelor of Science in Mechanical Engineering

These programs give our students a strong background in the fundamentals of mathematics, science, and engineering.

The educational mission of the department is to graduate students who have fundamental technical knowledge of their profession and the requisite technical breadth and communications skills to become leaders in creating the new techniques and technologies which will advance the general field of mechanical and aerospace engineering sciences.

• You can now get your up-to-date Degree Progress Report (DPR) on-line from Undergraduate Studies. Note that the DPRs are only updated several times per semester and may not show recent changes. Note that if there is an error in your DPR, or if you have course waivers or substitutions in major/minor requirements these must be submitted to Undergraduate Studies using the DPR Correction Sheet which is also available on-line.
• Unsure of your graduate requirements? Lost your Undergraduate Handbook from when you were a freshman? The Handbooks for Undergraduate Students (which are different for every incoming class and describe the complete major and minor degree requirements for every CWRU program) can now be downloaded here.
