Is it necessary to inform colleges about my decision?

After receiving offers from several colleges, do I have to formally let each one know my decision, even the ones I decide not to attend? What's the etiquette for this situation?

You're definitely on the right track here with thinking about college decisions. Once you have decided on the college you want to go to, it is professional and considerate to inform the other colleges of your decision. Remember, there may be other students on a waitlist who would love to have your spot.

Usually, the college's admissions portal will provide an option to accept or decline your offer of admission. It is as simple as clicking a button to indicate your decision. In case you have received any scholarships or financial aid from a college you're not attending, be sure to decline those offers as well. This way, the college can offer that assistance to other students who may need it.

Notifying your decision gives the colleges a final headcount for planning their upcoming academic year, such as housing arrangements, classroom sizes, etc. Another point to bear in mind is that if you've applied for financial aid, not responding could potentially leave that aid unavailable for other students.

So, letting the colleges know isn't exactly mandatory, but it's highly recommended as it allows colleges to manage their admission process more efficiently while potentially helping other students. It's a small gesture but one that can make a significant difference.
