Important Note: This list is not exhaustive, and other institutions like Imperial College London, Nanyang Technological University, and several other universities in the US, Europe, and Asia consistently rank highly depending on the ranking system. The "best" college will also depend on the specific engineering discipline you are interested in. Always research specific programs and faculty within your area of interest.
