From a Floating resident: Tufts didn't fill because the triple board program only takes folks every few years. When they decide not to take anyone, then the pedi program can invite a few extra or decide not to fill the spots. This past year, they invited one IMG who had not participated in the match system and dropped the other spot. So, they never participate in the scramble but like to have a few flex spots for triple boarders...Unfortuately, it makes it look like the pedi program didn't fill, but its really the triple board- for some reason they have to keep the same # of spots every year even when they characteristically only take new residents every other year. This year, they are interviewing so those spots should fill. I think its a good thing for a program not to fill every 10 years or so, to keep it on its toes! Boston programs always fill because of location, so Floating has never participated in the scramble.
