College Opportunity Fund (COF) is Colorado's support for higher education utilizing tax dollars. So with it, your tuition is less, but you must complete the COF application during your CU Denver application process in order to receive it. Since there is no distinction between online and on-campus courses (some institutions are online only) our in-state undergrads can qualify for this stipend regardless if their courses are on-campus or online.
More details about COF are available through the Office of the Registrar website.
