Since Katz is the graduate business school under the University of Pittsburgh, here are some relevant undergraduate admission requirements for Pitt (for those applying to business majors or in general):

Applicants must complete college preparatory coursework in high school: e.g. courses in English, math, science, social studies. 

Pitt has adopted a test-optional policy for undergraduate admission (SAT / ACT scores are optional) through Fall 2028. 

A holistic review is used: high school transcript, rigor of courses, extracurriculars, personal statements / essays, etc. 

Applicants need to submit their official transcripts and records of academics.
