The summer before junior year is the most important three months in the college application timeline — but most students waste it. NPR reported in May 2026 that 52% of college applicants now submit standardized test scores, the highest share since 2019, as selective schools bring back testing requirements. If you're entering 11th grade in fall 2026, the decisions you make this summer will determine whether you're prepared — or scrambling — when applications open next August.

The summer before junior year feels like free time. It's not. It's the last extended window before the college application process fully takes over your life — and how you use these three months determines whether you're ahead of the game in fall 2026 or constantly catching up through it.

This checklist is sequenced by what needs to happen first. Not everything is equally urgent.

First: Know What's Changed About Testing

In May 2026, NPR reported that 52% of applicants to four-year colleges submitted SAT or ACT scores during the 2025-26 cycle — the first time the submission rate has exceeded 50% since the 2019-20 school year, before the pandemic made testing optional.1 That share was up 10% from the year before.

Why does this matter for rising juniors? Because you'll be applying in fall 2027, and the schools that have reinstated testing requirements since 2024 include some you're likely considering. Harvard, Dartmouth, Brown, Cornell, and the University of Pennsylvania already require scores for fall 2026 applicants. Princeton will require them starting with the Class of 2031 — fall 2027 applicants.2

If you're aiming at selective schools, test-optional is no longer the safe default. The students who do best this application cycle are the ones who start preparing for the SAT or ACT before junior year begins — not in October when it's already crunch time.

The Checklist

June: Set the Foundation

Register for a fall SAT or ACT. The SAT offers test dates in August, October, and November. The ACT has dates in September, October, and December. Registering now secures your spot and creates a hard deadline that makes summer prep feel real instead of optional. Check ACT test dates for 2026-27 for registration deadlines.

Take a practice test cold. Before you start any prep, sit down with a full practice test under timed conditions. Don't study first. This baseline score tells you where you actually are — not where you hope to be. What counts as a good SAT score varies by school, so check your target schools' middle 50% ranges when you evaluate your baseline.

Make a preliminary college list. You don't need final answers now. You need enough structure to make this summer's research productive. Aim for 10-15 schools across reach, match, and likely categories. How to build a college list walks through the framework. Pay attention to testing policies at each school — they've been in flux since 2024, and many public universities have officially ended test-optional policies.

July: Do the Work

Begin structured test prep. Two to three hours per week of focused SAT or ACT prep — not passive reading, but active practice with immediate review — is more effective than a cram session in September. Six weeks of consistent prep before a fall test date will move your score more than any last-minute sprint. For ACT-specific prep, the ACT prep guide covers section-by-section strategy.

Research two to four schools in depth. Not "look at the website" research. Read what faculty are publishing. Find out what the first-year experience actually looks like. Email admissions offices with one genuinely thoughtful question. This is also when you should look at whether applying early decision is right for you — early decision vs. early action explained lays out the tradeoffs.

Visit at least one campus. If you can visit two or three, even better. Nothing replaces walking around a campus to get a sense of whether it feels right. But even a virtual tour with an admissions session is better than forming impressions purely from rankings lists.

August: Set Up Fall

Ask for letters of recommendation before school starts. This is the task most juniors delay until October — which is when teachers are already overwhelmed with recommendation requests. Teachers who get asked in late August can write a more thoughtful letter and get it submitted before crunch time. Junior-year teachers write the best letters, but asking a sophomore teacher you had a meaningful relationship with is also legitimate.

Read about the Common App. Applications open August 1, 2026. You won't be completing them until fall of 2027, but what to do before Common App opens August 1 explains how to set up your account, understand the structure, and avoid common early mistakes that cost students later.

Look up FAFSA timing. The 2027-28 FAFSA — the one that applies to students enrolling in fall 2027 — will open in fall 2026. You won't be filling it out yet, but understanding how the FAFSA works and what it requires now means you won't be surprised by it during application season.

The single highest-leverage thing a rising junior can do this summer is take one timed, full-length practice test and then spend the rest of summer closing the specific gaps it reveals. Not general prep — targeted prep. A student who knows they're losing 8 points per section on reading comprehension should spend the summer on that, not on math drills they've already mastered.

What Doesn't Need to Happen This Summer

You don't need to narrow your college list to a final 10. You don't need a polished application essay. You don't need to have your major decided.

What you need is a test score trajectory, a working list of schools, two or three genuine relationships with teachers who might write your recommendations, and a clear picture of how your fall semester fits into an application timeline you understand.

The students who feel calm during fall of junior year are almost always the ones who used this summer to do specific, manageable things — not the ones who stressed about everything without doing anything.

For rising seniors who are one year further along, the rising senior summer checklist covers where you need to be by August if college applications open in a few months. And if you're a junior thinking about applying early, the early decision and early action guide explains the calendar in full.
