* For-profit college: This is the most straightforward and widely understood term.
* Proprietary college/school: This term emphasizes the private ownership structure.
* Investor-owned college: This highlights the involvement of investors in the ownership and operation.
* Privately held college: This describes the ownership structure, as opposed to a publicly traded company.
The best term to use depends on the context and the nuance you want to convey. Often, "for-profit college" is sufficient, but if you want to emphasize the ownership structure, "proprietary college" or "investor-owned college" might be more precise.
