How to Stay Busy During Summer

Of all the seasons in the high school calendar, summer is the one that matters most to college admissions officers, and yet it is the one students take least seriously. That disconnect is worth examining, because understanding why summer carries so much weight is the key to using it well.

Here is the core insight: during the school year, the law compels you to be somewhere doing something. You attend class because you have to. You study for exams because failure has institutional consequences. Your behavior during the academic year is, in a meaningful sense, externally regulated. Colleges can see your grades and your course rigor, and they appreciate what those numbers represent. But what they cannot fully see during the school year is you, the person, operating freely.

Summer changes that. When school ends, no one is telling you where to go or what to do. There are no teachers, no administrators, no mandatory commitments. You are left to your own devices in a way that closely mirrors what your life will actually look like once you are living on a college campus away from your family. This is not a coincidence. Admissions officers are, above all else, trying to answer one question: what kind of person is this applicant going to be on our campus? Summer is when you give them the clearest, most honest answer to that question, because it is the only time of year when your choices are entirely your own. If you spend it well, you show them exactly who you are. If you waste it, you show them that too.

The summer of junior year is especially consequential. At that point in the admissions timeline, it is the last full summer colleges will be able to evaluate before you apply. It is your best, and often final, opportunity to demonstrate initiative, intellectual seriousness, and the kind of agency that colleges are hungry to see. Squandering it is not a recoverable mistake.

So what does it mean to actually stay busy? Here are six meaningful ways to spend your summer, along with some guidance on what counts and what does not.

Take Community College Classes

Enrolling in community college classes over the summer is one of the most underrated moves a high school student can make. These courses are real college coursework, taken alongside real college students, graded on a real transcript. What matters here is that the classes are fully accredited and that they assign letter grades. Pass/fail arrangements do not carry the same weight, and neither do the expensive pre-college programs hosted by universities that only grant internal credit. If you cannot transfer the credit to another institution, it does not signal academic rigor to colleges.

The scheduling flexibility of quarterly systems makes community college particularly powerful in the summer. Some schools operate on quarters rather than semesters, which means you can pack two full terms of coursework into a single summer. A highly ambitious version of this would look something like Calculus I and Calculus-Based Physics I in the first quarter, followed by Calculus II, Calculus-Based Physics II, and Linear Algebra in the second. That is an extreme example, but it illustrates the sheer ceiling of what is possible when you take the quarterly system seriously. Even a more moderate version of this approach, say one or two rigorous STEM courses across the summer, sends a strong signal to admissions officers about how you spend your time when no one is forcing you into a classroom.

Work a Job

Colleges respond well to students who hold summer jobs, and for good reasons. Working for pay introduces real stakes. A boss who is not your parent, customers who are not your friends, and a paycheck you actually depend on create conditions that test your character in ways that academic settings simply cannot replicate. There is something colleges genuinely respect about a student who shows up and earns.

It is also worth noting that the labor market has made even entry-level service jobs genuinely competitive. Getting hired somewhere is a real accomplishment, and doing your job well over the course of a summer demonstrates reliability, work ethic, and social maturity.

Working for someone else is not the only option. Self-employment is just as legitimate and often more impressive. Tutoring students in subjects you excel in, coaching youth sports, teaching music lessons, or running a small service business all demonstrate entrepreneurial thinking and a willingness to build something from nothing. The most important thing is that the work is real and the stakes are real.

Volunteer, But Make It Count

Volunteering can be a meaningful way to spend part of your summer, but the qualifier here matters enormously. What colleges want to see is specialized, skilled contribution, not generic service. There is a significant difference between applying a technical skill you have spent years developing in service of a community organization, and showing up to perform tasks that require no background or expertise.

Using your programming knowledge to help a local nonprofit build a data pipeline or develop a predictive model for their outreach efforts is the kind of volunteering that lands. Serving food at a soup kitchen on a Saturday afternoon is not something that distinguishes you in an application pool, even though it is a kind and worthwhile thing to do. When you volunteer, ask yourself whether the organization would struggle to find someone else to fill your role. If the answer is no, look for a higher-leverage way to contribute.

Pursue Research

Conducting academic research over the summer is one of the most powerful things you can do for a college application, particularly if you are aiming for schools that take undergraduate research culture seriously. Programs like SSP are extraordinary opportunities, but they are also extraordinarily competitive. Not getting into a selective summer research program is not the end of the road.

Cold emailing professors to request a position in their lab is a legitimate and surprisingly effective strategy. Most students never try it because it feels presumptuous, but researchers are often genuinely open to motivated high school students who can demonstrate relevant skills and clear intellectual curiosity. The key is to reach out with specificity: identify the professor's current work, explain why it interests you, and articulate what you can actually contribute. Generic outreach does not work. Targeted, substantive outreach sometimes does.

If you are planning to pursue a research position through cold outreach, do not wait until June to start sending emails. Begin in the spring so that you have a position secured before summer begins. A productive summer of research does not happen by accident.

Engage With Your Community

High school students who genuinely want to be civically involved face a structural obstacle: city council meetings, town halls, and community board sessions almost always happen during school hours. The school year makes real community engagement nearly impossible. Summer removes that barrier.

When you have the time and freedom to actually show up to these meetings, you encounter real people grappling with real problems. You learn what your community's actual needs are, which gives you something concrete to act on. The most impactful version of this is becoming a bridge between a specific segment of your community and the people who have the power to respond to their concerns, whether that means elected officials, community organizers, or institutional decision-makers. Being the person who connects those two worlds is meaningful work, and it makes for a genuinely compelling story in a college application.

Build Something

Independent passion projects can be some of the most memorable things in an application, precisely because they are not the result of any external requirement. If you want to build a functioning retro computer from scratch, wire up your own radio to communicate with the International Space Station, or design a prototype for some machine or tool you have been thinking about for years, then do it.

The caveat is that for this to carry real weight in admissions, you need to document your work publicly as you go. That means logging your progress, your setbacks, and your breakthroughs somewhere others can find and learn from. A GitHub repository, a YouTube channel, a Substack, a personal blog, whatever format suits the work. The public documentation serves two purposes: it makes your process legible to admissions readers who cannot visit your garage, and it demonstrates the kind of intellectual generosity and openness that colleges find genuinely attractive.

A Word on Travel

If you are aiming for T20 schools, traveling over the summer, and especially over the summer of your junior year, is not the move. Admissions readers are professionals who read thousands of applications a year on salaries that do not reflect the scale of the task. An essay about your gap year in Southeast Asia or your family vacation in Europe is not going to land the way you think it will. It signals passivity. It signals access. And frankly, it tends to make underpaid readers feel more annoyed than impressed.

There is one exception. If you are participating in a sponsored program that involves genuine hard work conducted overseas, that is different. Service expeditions, international research placements, and similar programs where the primary activity is productive rather than recreational can be framed appropriately. But if the honest description of your summer is that you traveled, sightsaw, and relaxed, that is not material for a college essay, and it should not be the centerpiece of your summer.

Summer is short. Use it.
