Groff Community College is the college which Hayley attends. It is frequently referred to as being for dumb people by Steve but also by Hayley when she says she needs 85 dollars for a semesters tuition. It also harbors a Theta Sigma (ΘΣ) frat house and the School of Arts & Crafts.
It's noted in "The Bitchin' Race" that Hayley has dropped out of college. However, she was still taking classes in "Funnyish Games". In that same episode, Steve took Architecture 101 at Groff despite being still in high school. Hayley came close to graduating in "Pride Before the Fail" but is still a student.
She briefly takes investigative journalism in "Hot Scoomp" before dropping out of the class.
