What are my chances of admission?

There are always more qualified applicants than space available in our programs. Therefore, our process is competitive, and we must deny admission to some students with good academic records. We typically have space for approximately 25-35% of all students who apply however this number changes depending on increases in funding. It's also important to note that we do not admit differently between Computer Science and Computer Engineering, we consider all applications together and admit without taking specific major into account. The admit rate in 2020 was 28% (113 admitted/402 applied), in 2021 it was 30% (165 admitted/554 applied), in 2022 it was 30% (134 admitted /444 applied) and in 2023 it was 33% (165 admitted /495 applied)

All applications are reviewed by the Allen School Undergraduate Admission Committee, comprised of faculty and advisers. We use an evaluative, rather than a quantitative, process in our admission review. This means our decisions are based on more than simply which applicants have the highest grades. We do not tally up points; rather, we form an overall evaluation based on academic background and other factors, such as outside interests and activities, evidence of leadership and a sense of direction, and life experience. We do not expect all students to excel across the board, but achievement in relevant academic areas or evidence of overcoming hardships can strengthen an application.
