Summer melt is when students who commit to a college in the spring, often with a paid deposit, don’t show up in the fall. You prevent it by treating the summer as its own stage: track every step each deposited student still owes, and reach each student about the step they’ve missed, from the office that owns it.
It’s a bigger leak than most enrollment plans account for. The Strategic Data Project’s Summer Melt Handbook estimates that summer melt ranges from 10% to 40% of college-intending students.
The summer is crowded with steps. We mapped 13 target actions between admission and the first day of class: accepting the offer, paying the deposit and the housing deposit, paying tuition, attending orientation, booking a first advising appointment and registering for classes among them. A student can stall at any one, often without telling anyone.
This guide covers what causes summer melt, how to spot the students most likely to melt, seven ways to prevent it and how to measure it. For the full funnel, see our guide to college enrollment marketing. To have us work your deposited students through the summer, see our enrollment yield solutions.
What causes summer melt
The handbook lists the summer tasks that trip students up: “attending orientation; completing financial aid and other paperwork; paying for tuition, room and board, and student fees (including health insurance); taking placement exams; and selecting classes.” Behind those tasks sit a few common reasons.
- The bill. The first bill arrives, the aid package leaves a gap, or the FAFSA gets flagged for verification and stalls.
- Paperwork with no one to ask. Final transcripts, immunization records, placement tests and housing forms each come from a different office, and the high school counselor is off for the summer.
- Second thoughts. A student who isn’t sure they’ll fit in, or that the cost is worth it, has three months to talk themselves out of it.
- Life. A summer job, a family need or a move pulls attention away from forms that seem far from urgent.
How to spot the students most likely to melt
The students to reach first are the ones with steps still open. Pull a list of deposited students in May and flag anyone who hasn’t:
- completed the FAFSA, or cleared verification;
- accepted their aid package or set up a payment plan;
- sent a final high school transcript;
- signed up for orientation;
- submitted the housing deposit, if they’re living on campus;
- registered for classes.
Refresh the list every week. A student with three open steps in July needs a different message than a student with one.
7 ways to prevent summer melt
1. Give every summer step a deadline and an owner
List each step a deposited student has to finish, the date it’s due and the office that owns it. A step with no owner is a step nobody follows up on.
2. Send one message per missing step
Generic “we can’t wait to see you” messages don’t move a student who is stuck on a form. Name the missing step, say how long it takes and link straight to it.
Picture a deposited student who hasn’t signed up for orientation by late June. A text from the Orientation office reads: “Fall orientation dates fill by July 15. Pick yours in two minutes: school.edu/orientation.” The deadline makes it urgent, and two minutes makes it doable. That’s self-efficacy, one of the motivational principles behind every GuidePost we build, paired with urgency.
3. Send it from the office that owns the step
A message from Financial Aid about the aid package, or from the Registrar about classes, tells the student who to contact. Every deposited student can be reached across five channels: social media, streaming TV, email, SMS and direct mail, each timed to the step they’re on.
4. Settle the money question early
Explain the first bill and the aid offer in plain language before the bill arrives. Offer payment plans, help with verification and a named person to call. More in FAFSA outreach.
5. Keep belonging alive over the summer
A deposited student who knows a classmate, an advisor or a club is less likely to drift. Introduce admitted students to each other, book the first advising appointment before fall and share what the first week looks like.
6. Bring families in
Parents and guardians often fill out the forms and pay the bills. Give them their own messages about deadlines, costs and who to call.
7. Keep going until census
Melt doesn’t end in August. Keep reaching students through the first weeks of class, until they’re registered, attending and past the census date.
What the research says about summer outreach
Targeted summer outreach works. At Georgia State University, an AI chatbot that texted admitted students in summer 2016 reduced summer melt by 21.4%, in a study of 3,745 students who got the messages and 3,744 who didn’t.
Generic outreach at a distance doesn’t. A study of more than 800,000 students found that national and statewide campaigns urging FAFSA completion had no effect. The researchers point to messages that were more generic and less personal than in earlier local studies, which also had partners with close ties to the students.
The difference is specificity. Messages that name the student’s own missing step, from their own college, get acted on.
What this looks like in practice
At a top-100 Northeast university, 1,999 admitted students received outreach from May 15 to August 31, 2026, and 83 were held out at random. Of the students who got the outreach, 224 paid their deposit, a rate of 11.21%. Of the holdout, 3 did, a rate of 3.61%. That’s a 210% lift, significant at 95% confidence. That study measured deposits; the same approach, one message per missing step measured against a holdout, carries through the summer to orientation and registration.

How to measure summer melt
- Measure melt by census date. Divide the deposited students who weren’t enrolled at census by all deposited students.
- Track each step. The share of deposited students who finished the FAFSA, orientation and registration shows where the summer is leaking, weeks before census.
- Find out where melted students went. The National Student Clearinghouse’s StudentTracker service shows whether students who didn’t arrive enrolled somewhere else.
- Compare against a holdout. Keep a random group of deposited students out of your summer outreach, the same students the whole time. The gap is what the outreach changed. New Motimatic campaigns hold out a random 5% of the list. More on how we measure.
Common questions about summer melt
When does summer melt happen? Between the commitment in the spring and the census date in the fall. Most of the steps that cause it fall between May and August.
Is summer melt the same as low yield? No. Yield is about getting admitted students to commit. Melt happens after they commit.
Does summer melt happen at community colleges? Yes, in a different shape: students who apply or register in the spring and never attend. The fix is the same: track the steps each student still owes and reach them about the next one.
Which students should we reach first? Students with the most open steps, especially an incomplete FAFSA or an unpaid bill, and students who haven’t signed up for orientation.
