What doest priority mean for a college application process?

My daughter received several offers of "priority" applications from several schools this year. She did respond to one. The applications were not requested by her but were sent to her because of test scores and grades or something like that. Her priority application was fee-free and was handled with speed and less red tape. It was shorter than some applications, with less essay requirements. She received notice of acceptance about a month after she completed the application.
