A state university system in the United States is a group of public universities supported by an individual U.S. state or a similar entity such as the District of Columbia. These systems constitute the majority of public-funded universities in the country. Each state supports at least one such system.
A state university system normally means a single legal entity and administration, but may consist of several institutions, each with its own identity as a university. Some states—such as California and Texas—support more than one such system.
State universities get subsidies from their states. The amount of the subsidy varies from university to university and state to state, but the effect is to lower tuition costs below that of private universities. As more and more Americans attend college, and private tuition rates increase well beyond the rate of inflation, admission to state universities is becoming more and more competitive.
Some states maintain a separate system for state colleges (often specified as community colleges, technical colleges, or junior colleges), that is distinct from their university system. Examples include the California Community Colleges System, the Florida College System, and the Technical College System of Georgia. In these states, colleges focus primarily on awarding two-year associate's degrees and professional certificates, while universities focus on four-year bachelor's degrees and more advanced degrees. The California Community Colleges System is the largest in the world. In 2009 the Florida College System changed its name from the Florida Community College System, reflecting the fact that some of its colleges now offer four-year degrees. Some of its colleges were designated "state colleges", distinguishing them from community colleges in that they offer more four year degrees than community colleges.
