Programme signals are the one part of your application where scarcity is the point. You get a handful; every programme knows you had a handful; and where you spent them tells each programme how serious you are. That makes signals a strategy question, not a wish list.
What a signal does and does not do
A signal raises the chance your application is reviewed by a human. That is the whole mechanism: it answers the reviewer's quiet question, "would this applicant actually come here?", and an answered question earns a closer look. What a signal does not do is override the file. It buys a look, not a pass; the file still has to survive the look.
The IMG-specific rule
Before you spend anything, split your list into programmes that take IMGs and programmes that do not. A programme that has not ranked an IMG in years is not one signal away from starting with you; the signal is spent answering a question the programme never asks. The public record is checkable: current resident rosters, programme pages, and the IMG-friendliness patterns visible in Match data. Signalling a programme with zero IMG history is the single most common way applicants waste their scarcest resource.
A signal cannot change a programme's policy. It can only move you up the pile at a programme whose pile you were already in.
A sane allocation
- Spend most signals on realistic targets: IMG-history programmes where your scores and experience sit inside the range they actually interview.
- Spend one or two on strong-fit reaches, reaches by competitiveness, never by IMG policy: the programme must still have an IMG track record.
- Spend none on safety programmes that interview applicants like you at high rates anyway; the signal adds nothing there.
- Geography counts as evidence. A signal plus a concrete tie to the region reads as intent; programmes filter for applicants likely to accept.
Takeaways
- Filter your list for IMG history before any signal leaves your hands.
- Signal where you are plausible, not where you are dreaming.
- Treat each signal as the answer to "would you come?", and make sure the rest of the file supports the yes.
