Every applicant going through ERAS has heard some version of the same warning: the first screen decides everything, and nothing else about your application matters until you clear it. AAMC's newest program signaling data doesn't erase that fear, but it does complicate the story in a way that matters — especially for IMGs.
What AAMC's Program Signaling Data Actually Shows
AAMC recently updated its ERAS guidance with survey data on how residency programs actually use program signals. Three numbers stand out:
- 96% of surveyed programs said they used signals to help decide whom to invite to interview.
- 90% said signals helped them identify applicants they would have otherwise overlooked.
- Sending a signal was associated with a higher probability of receiving an interview across every participating specialty, though AAMC is clear that it never guarantees one.
That middle statistic is the one worth sitting with. Overlooked isn't a soft word here. It describes something specific: an application that a program's initial screen would have passed over, until a signal made a reviewer look again.
How ERAS Program Signals Work
Before going further, it helps to be precise about what this tool actually is, because a lot of applicants use it without fully understanding it.
When you submit your ERAS application, each specialty allocates a limited number of signals you can send to individual programs. A signal is a direct, deliberate way of telling a program: I am genuinely, specifically interested in you. The exact number of signals varies by specialty, based on how many programs exist in that specialty and how many applications programs in it typically receive.
Some specialties use standard signaling, where a program simply sees "Yes" if you signaled them. Others use tiered signaling, where you can send a Gold signal (your most preferred programs) or a Silver signal (programs you're strongly interested in but rank slightly below your top choices).
Only the programs you signal and apply to will ever see that signal. If you don't signal a program, or you signal a different one instead, that program receives no information about your interest at all. Programs are officially instructed to treat signals as one data point among several, not a stand-in for the rest of the application. But AAMC's own guidance acknowledges that some programs use signals during initial screening, before a full application review happens. That's exactly where the 90% figure comes from.
Why ERAS Program Signals Matter More for IMGs
Every IMG has internalized some version of the belief that the first screen is the whole game — that a board score or a school name filters an application before a human ever reads the personal statement or the letters. AAMC's data doesn't fully contradict that fear, but it does offer a counterweight.
"Overlooked" describes exactly what happens when a screen filters on criteria that don't capture what an applicant actually brings: a board score well above a program's stated cutoff but from a school reviewers don't immediately recognize, strong international clinical experience that doesn't map cleanly onto a US-trained reviewer's mental model, or genuine alignment with a program's specific mission that never shows up in the numbers a screen is built to catch. A signal doesn't rebuild that screen. It gives an applicant something more targeted: a way to interrupt it, one program at a time, by putting a small number of clear, deliberate flags exactly where they want a human being to look twice.
How to Build an ERAS Signal Strategy That Actually Works
The 90% figure only helps applicants who spend their signals with intention. A few principles worth building into your strategy:
- Research every program before signaling it, not just the reach programs at the top of your list. A signal on a program that's a poor fit doesn't do what the data suggests signals can do.
- Weigh program competitiveness honestly against your own application strength. Signals work best when they're spent on programs where a closer look genuinely could change the outcome.
- Prioritize mission fit over name recognition. Programs report using signals partly to gauge genuine interest, and genuine interest is easier to demonstrate when the fit is real.
- Treat every signal like it's worth something, because according to AAMC's own data, it likely is.
What This Means for Your Match Strategy This Cycle
None of this changes how competitive the Match has become, and it doesn't erase the structural disadvantages IMGs continue to navigate in this process. But it does mean the tools available to interrupt those disadvantages are more effective than a lot of applicants assume. Nine out of ten programs are telling AAMC they're paying attention to signals closely enough to catch applicants they'd have otherwise missed. The question for every IMG heading into this cycle is whether their signal strategy is built to be noticed — or built on instinct.
How Residents Medical Builds Your Signal Strategy
Understanding the data behind program signaling is one thing. Building a signal strategy around your specific application — your board scores, your clinical background, and your target list of programs — is another.
This is where Residents Medical comes in. Our team works directly with IMGs to turn AAMC's guidance into an actual plan: which programs deserve a Gold or Silver signal, which reach programs are worth the risk, and which signals are better spent on programs where a closer look could genuinely change the outcome. We help applicants research program fit at the level AAMC's own data suggests matters, so signals land with intention instead of instinct.
The Match process rewards preparation, and preparation is easier with someone who has done this before sitting next to you. You do not have to figure out your signal strategy alone, and you do not have to guess at what a program is really looking for.
