No. Working on campus and during the summer is an option available to students to meet their estimated cost, but Yale does not require that any student work. Students who prefer not to earn income through term-time and/or summer employment may opt to meet some or all of their Student Effort with funds from outside merit scholarships or to take out a small student loan. Unlike many other universities, Yale allows funds from outside merit scholarships to reduce or eliminate the Student Effort. Pursuing term-time and summer work is one option for students and families to meet their estimated Net Cost.
