The University System of Georgia (USG) is the State of Georgia Government Agency that includes 28 public institutions of higher learning in the U.S. state of Georgia.
 The System is governed by the Georgia Board of Regents.
 It sets goals and dictates general policy to educational institutions as well as administering Public Library Service of the state which includes 58 public library systems.
 The USG also dispenses public funds (allocated by the state's legislature) to the institutions but not the lottery-funded HOPE Scholarship.

 The four larger systems are the University System of Ohio, City University of New York, California State University, and the State University of New York.
 USG institutions are divided into four categories depending on their mission statements.
 The categories include research universities, state universities, state colleges and regional universities.
A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure.
 Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names.
 On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students in theory enjoy the opportunity to learn from such experts.
 On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking.
