The university is considering a 6 percent tuition increase for the next academic year. 

This May, Colorado State University may vote to increase its tuition rates again. As the Coloradoan reports, it's part of a much longer practice: In-state tuition has risen every year since the 1970-71 school year.

Rick Miranda, executive vice president at CSU, said that inflation, less money from the state, and the improved education are what drives up the cost.

"(With inflation), it's the same old, same old … it goes up every year," Miranda said. According to the U.S. Bureau of Labor Statistics, $120.19 in today's dollars has the same buying power as $100 a decade ago. In terms of CSU undergrad tuition, such inflation would account for a roughly $1,300 increase in the in-state rate over the past 10 years.
