A graduated Student Facilities Fee based on hours of enrollment—a maximum of $25 per semester for in-state students and $150 for out-of-state students—was approved by the UT Board of Trustees at its July 2000 meeting, effective fall semester 2000. One-third of the fee was designated for classroom upgrades, one-third to expand technology in instruction, and one-third to fund campus infrastructure projects. In 2004, following a referendum in which students voted to increase the Facilities Fee to provide dedicated funds for environmental initiatives, the fee was expanded to incorporate the dedicated increase.
