How do people find internships other than through their school?

Hi, I’m a high school senior and I was hoping to intern (preferably paid) this summer. I already applied for a local library internship that i attended last summer but I want another/more option(s).

I already looked through all the internships opportunities my school posted but those are limited. I know people often get internships through some other source but are they are personal connections or what? How does one find an internship for the summer other than through school resources and personal connections? Or are those the only methods?

My kids used personal connections. There are tons of high school kids looking for jobs and internships and there are only so many positions that will allow inexperienced students to intern at established companies.

Some companies post internships on their websites.

What field are you interested in? Try contact companies in your area and ask if they hire HS students for internships. Also ask at you HS counselor’s office.
