If you want to pursue a STEM major in college, it's worth thinking of ways to build your skill sets and showcase your interest, initiative, and leadership. Admissions officers look for multiple, well-presented components in a student’s application for a field as popular as STEM - including research you’ve conducted, passion projects, internships, and strong essays.
If you’re looking for STEM internships as a high school student, here’s a list of 11 of the best ones that you can apply to! Most of these internships are fully funded by the company/organization and provide a stipend! We’ve covered a variety of STEM areas, such as life sciences, medicine, aerospace engineering, and sustainability. We've also curated a larger list of internships, but this one is specifically for the most competitive internships in STEM.
To shortlist the best programs for this list, we compared the acceptance rates and cohort sizes of each of these internships. Acceptance rates are a pretty good indicator of selectivity (and, hence, prestige).
There are two ways in which we’ve calculated these acceptance rates -
Information from the organization’s official website, newsletters, and company reports, as well as mentions by alumni and new interns on their personal blogs.
Estimated acceptance rate based on the number of interns in each cohort.
For example, if the cohort size is 10-12 students, and the average number of applications is about 600-800 from across the country, we can estimate the acceptance rate to be about 2- 4%. However, if you want to build specific skill sets or earn a particular stipend, don’t limit yourself only to the acceptance rates, and factor other aspects in.
Here are the 11 best STEM internships for high school students! Note that the following information is based on the most recent program, with dates subject to change but generally similar from year to year.
Acceptance Rate - 25%, with each company accepting about 2-3 students for each cohort. The upcoming summer cohort has about 100 students.
Ladder Internship is a selective program for high school students to work with start-ups.
