I always hated that, too. We also went during the Summer.
When I was there we went year round, 5 days a week for 4 hours a day, with a two week between one or two of the quarters. It sucked but it also meant you could earn a B.A.S. "degree" in three years for about 25K.
I think they do this because the programs have more credit hours than usual, like 180 credit hours for a Bachelors "degree" at ITT versus a real one for about 120 credit hours. I forgot about this when I was calculating the current cost of ITT a few years ago; people were talking about spending 80K and coming up with around 55K.
Oh yeah, they f*** you with bogus credits quantities, too.
