There are many public-scale college students. Because most schools have an agreement with the state government on the Moreel Act, they adopt a policy of low admission standards and low tuition fees for students, which leads to poor enrollment. (Of course, there are exceptions, such as Berkeley University and Michigan University. ) Private enterprises are generally small in scale and have strict admission conditions for students.

Public universities are not allowed to have religious requirements, and some private universities can have religion.

Public universities receive government funding, so tuition fees are lower, while private universities mainly rely on alumni donations and tuition fees, so tuition fees are higher.

Generally speaking, public universities do better in sports (NCAA) than private universities. Of course, there are exceptions in private universities (Stanford University, Duke University, Notre Dame University).

Private universities have more scholarship opportunities than public universities.

Temple University, Pittsburgh University, Pennsylvania State University and other "state-related universities" are both public and private, so they have both public and private characteristics.
