If you are looking for a professional degree program, apply for the MAnalytics or MEng program. For more information about the differences between the MAnalytics and MEng programs, please see the FAQ here.
The MS and PhD programs are considered academic programs. The MS is a technical and full-time master's degree program. The PhD is a research-oriented academic program for those who have a clear research goal in mind. If you apply for the PhD without an MS degree, you will earn an MS degree while progressing to the doctorate degree.
Note: The MAnalytics, MEng, and MS programs are considered terminal degree programs, and students in these programs will not be allowed to continue on for the PhD. Prospective students who are interested in earning a PhD degree should apply to enter the PhD program even if they do not yet have a master’s degree.
