A college is a post-secondary educational institution that usually offers associate's and bachelor's degrees, or both. A university usually offers undergraduate (bachelor's) degrees and graduate (master's and doctoral) degrees.
A degree from any college or university is a valuable asset for future employment, as long as the school granting the degree has been regionally accredited.
Some colleges offer more affordable degree programs than universities, making them a cost-effective choice. A benefit of many universities is that they offer graduate programs for students pursuing advanced degrees.
Not all colleges are limited to undergraduate degrees, and not all universities provide degrees of higher quality or more prestige than colleges. Universities do not necessarily provide a better education than colleges, which is a commonly held misconception.
The quality of an institution and the degree programs it offers matter more than whether the school is a college or a university. Research any school thoroughly to verify that it is regionally accredited, offers the degree you seek and has the qualities most important to you.
