Congrats, your program wrapped.
Your interns are no longer working at your company, but this is not the end of the relationship. You have already put a lot of time and money into getting this far.
To make that tangible, add it up for one intern:
Recruiting costs about $6,275, based on NACE’s average campus cost-per-hire.
Salary costs about $11,200, at the $23.35 average hourly rate for twelve full-time weeks.
Add equipment, cohort events, and the manager and mentor hours nobody budgets for, and a conservative estimate lands somewhere around $20,000 per intern. That is before relocation or housing, which about half of employers now provide.
While these numbers vary across programs, we estimate a class of 100 interns is roughly a $2 million investment.
With an investment of that size, the real question is what you get back on it?
NACE puts average intern conversion at 63.1%, a five-year high and genuinely good news. It also means about 37 of every 100 interns leave in August without an offer. At $20,000 each, that is roughly $740,000 of your investment.
Not all of it is lost. Some interns were not a fit, and some were never eligible. But in most programs this talent pool goes unmanaged, or gets buried in a spreadsheet nobody opens. Nobody owns the relationship, nobody knows when those people graduate, and by January they have signed somewhere else.
Protecting that investment means treating the alumni window as a second recruiting phase. NACE makes the same point: engagement cannot be a ten-week summer pursuit, and it has to be maintained after interns return to campus.
Why We Built an Alumni Edition of the KEEP Framework
Part one of the KEEP Framework takes a candidate from offer acceptance to Day One. It assumes a start date exists. After we published it, early career leaders kept asking the same follow-up: what about the ones I cannot hire yet?
Early career is the one cycle where you onboard someone, run a program, offboard them, and then onboard them all over again months or years later. In between, a person you already hired, trained, and evaluated sits outside your systems and inside somebody else’s recruiting funnel. Standard keep warm starts at offer acceptance. For alumni it has to start before they leave, and for many of them it runs with no offer on the table at all.
Kick Off: Get Organized Before They Leave
This is tough to capture once the program is over, so make sure you get ahead of it when you can!
- Send the end-of-program evaluation two weeks before the last day, with reminders. Completion rates fall off a cliff once the intern is gone.
- Get input from the manager, the mentor, a peer, and the intern, then calibrate across the cohort so you are not ranking people by the generosity of their manager.
- Capture what you cannot get later. Personal email, personal phone, graduation month, and eligible start date, while they are still on site.
- Walk them through leaving. For most of your interns this is the first job they have ever left. They do not know what they can say publicly, what goes on a resume, or when their access ends.
Engage: Build a Cadence Around Their Calendar
Once a month, minimum, mapped to the academic year rather than your fiscal one.
- Reconnect on campus. Your alumni are already sitting on the campuses your team is flying to this fall. Have one co-host the info session, work the booth, or gather everyone for coffee the morning of the fair.
- Run an alumni spotlight series, alternating between intern alumni and employees who started as interns. The second one converts, because it answers the question they are actually asking.
- Keep the buddy relationship on a standing monthly hold. Thirty minutes, and it is the single tactic most likely to keep someone connected.
- Time swag to their year: finals, winter holidays, graduation.
- Tell them how the business is doing. Career stability is what this generation asks about most, and it is what most employer content avoids.
Enable: Equip Everyone Else to Show Up
Make it easy for your stakeholders to step up to the plate and keep your alumni warm.
- Give hiring managers the words, not just the ask. A three-sentence quarterly note they can customize in two minutes. Managers go quiet because they do not know what to say.
- Name each stakeholder’s piece. Recruiters own status updates, mentors own the check-in, campus leads own the fall travel map, IT owns the access handoff.
- Agree on what everyone says about headcount, and give a specific date rather than a season. Interns compare notes for years.
- Give recruiters more than one offer to make: a second internship, a fellowship, a co-op rotation, a paid term-time project.
- Turn alumni into ambassadors, and keep them connected to each other through a cohort group and an annual reunion.
Perform: Prove What the Talent Pool Returns
Start with the health of the pool: data integrity, who your top performers are and whether they have a role, and return interest measured with one identical question every quarter.
Then report what the pool returns to the business.
- Headcount filled from alumni versus net-new sourcing.
- Time to fill and cost per hire, alumni against net-new campus. Usually days versus weeks, at a fraction of the spend.
- Quality of hire and retention, where alumni win outright. NACE found more than three-quarters of hires who interned with the employer are still there after a year and more than half after five, against fewer than half and about a third for hires with no internship experience.
- Referrals sourced by alumni, including alumni you did not hire.
Only 6% of early talent teams tell us they feel very confident measuring campus ROI. A finite, named alumni pool is the easiest place to start, and it is the same discipline SHRM calls candidate rediscovery. Your intern alumni are the strongest version of that pool, because you did not interview them for an hour. You watched them work for ten weeks.
Put It Into Practice
The KEEP Framework: Alumni Edition is built to be opened, customized, and handed out. It includes the evaluation structure, the exit data capture list, an ownership matrix, ready-to-use templates, campus reconnect plays, an event playbook, a swag timeline, the engagement scorecard, and a 12-month calendar mapped to the academic year.
And if you want to see how Symba handles the mechanics, from alumni access that survives the corporate email shutdown to dashboards that flag who is going quiet, we’d love to show you.
