Rolling admissions means that universities assess your application on a first-come, first-served basis when they get it. There is usually no final deadline to apply. You just send in your application when it's ready, they have a look, and they get back to you fairly soon--usually around four weeks. Most--but not all--of the schools that have rolling admissions are large, state schools. They are large and robust enough to just look at each application as it comes in and decide if you're admissible or not without trying to "craft a community" or compare you to their other options. Some of the universities with rolling admissions are places you've probably heard of, like Penn State, Michigan State, and Arizona State. If you're looking at a college that has rolling admissions, especially if you're looking for a college because it has rolling admissions, there are a few things to understand.
