Do you mean with open admission to the major (needing only a 2.0 GPA and C grades in the prerequisites)?
Or would having to earn a high GPA or apply for competitive admission to get into a major, like at Purdue, Texas A&M, and many other schools be acceptable?
At many large state flagship schools, the popularity of the engineering majors exceeds the departments’ capacities, so they must choose between a “weed out” system (so frosh are uncertain whether they will be able to get into their majors, and may create a more competitive or cutthroat atmosphere) or admitting frosh directly to the major (which can make it more difficult to change majors).
