4+1 Bachelor of Science Degree with Wellesley College
The Olin 4+1 Program offers Wellesley College students an opportunity to obtain a second bachelor’s degree in engineering by completing a fifth year of study at Olin. Students enrolled in the 4+1 program begin their engineering study while enrolled at Wellesley; by the time they complete their Wellesley degree, 4+1 students must have completed all math and science prerequisites as well as five foundation courses, listed below. In their fifth year, 4+1 students enroll at Olin and spend both semesters in residence, completing major requirements as well as the engineering capstone.
The Engineering Certificate is not intended to serve as a pathway to the 4+1 Program. While there are some overlapping requirements between these two programs, the 4+1 Program requires an extensive set of course and credit requirements not only in engineering, but also in math and science. Students intending to apply for admission to the 4+1 Program will need to plan their schedules carefully and often take courses at different times compared to Engineering Certificate students.
Admission to the 4+1 program takes place in the student's junior year at Wellesley. Students admitted to the 4+1 program receive the Olin Tuition Scholarship for their year as Olin students, and may apply for additional need-based financial aid. Wellesley students who are admitted to the 4+1 Program must spend two full-time semesters in residence at Olin (living on campus).
4+1 Degree Requirements
All students wishing to complete the 4+1 program must fully satisfy Wellesley’s degree requirements prior to matriculating at Olin, and must also satisfy specific science, math and engineering requirements. The minimum distribution requirements for the 4+1 Degree are shown in the table below.

Design Depth and Engineering Capstone Requirements
In addition to prerequisite course work and Olin foundation courses, all 4+1 students must complete a design depth and engineering capstone requirement.
Design Depth Course - One of:
The approved design depth courses listed below adhere to four criteria: 1) focus on a major theme in design thinking covered at an advanced level, 2) involve substantial theoretical consideration of design principles, processes or methods, 3) present the theme and theoretical consideration at an interdisciplinary level covering material that is relevant and accessible to multiple disciplines, and 4) provide substantial project experience that aims to create an artifact such as a component, process or system to meet needs, demonstrate possibilities or offer critique.

Major Requirements
Choose one of the three Olin majors, Electrical and Computer Engineering, Engineering or Mechanical Engineering and follow the degree requirements as outlined.
It is expected that an Olin major will be comprised of Olin engineering, or related courses. However, if approved, a maximum of two courses (or eight credits) may be transferred from another institution (Wellesley or other).
Notes regarding equivalences and terms
- Credit Equivalences between Wellesley and Olin: 1 or 1.25 Wellesley Units = 4 Olin Credits
