Degree options will give students broader opportunities to tailor their academic experiences and prepare for evolving careers in science, research and technology

Beginning fall semester 2026, the College of Arts and Sciences at the University of Colorado Boulder will launch a suite of Bachelor of Science (BS) degrees across many majors in the Division of Natural Sciences, expanding opportunities for students to tailor their academic experiences and prepare for evolving careers in science, research and technology. 

The new degree options in astrophysical and planetary sciences; atmospheric and oceanic sciences; biochemistry; chemistry; geological sciences (renamed Earth Science in Fall 2026); geography; integrative physiology; mathematics; molecular, cellular and developmental biology; neuroscience; physics; and statistics and data science reflect a growing demand from students, faculty, alumni and employers for programs that signal greater specialization in the sciences. 

“We’ve listened to feedback from our students who want more clarity in how their degree reflects the work they’ve done,” says Irene Blair, dean of the Division of Natural Sciences. “The sciences are evolving rapidly, and our degree offerings must evolve with them. These new BS pathways empower students to pursue the laboratory, mathematical and computational studies they value while maintaining the flexibility that defines a liberal arts education.” 

Most students in the natural sciences will see little or no change to their coursework; the introduction of BS degrees provides clarity about their specialization on their diplomas. At the same time, existing Bachelor of Arts (BA) options will remain available in many natural sciences departments – applied math, astrophysical and planetary sciences, ecology and evolutionary biology, environmental studies, geography, mathematics, psychology, physics, and public health – ensuring students retain the flexibility to explore interdisciplinary interests or combine majors, with their natural sciences major continuing to signal the skills and specialized knowledge they have gained. 

“Offering both BA and BS degrees reflects our belief that success in science takes many forms,” says Blair. “We want students to have the freedom to pursue what inspires them, whether it’s deep research, broad exploration or innovative work across disciplines.” 

The College of Arts and Sciences will share detailed guidance for current students and academic advisors in the months leading up to the August 2026 launch. For more information, see the BS degree FAQ page, which outlines the degrees that will automatically convert to the BS, those that require additional coursework, new degree offerings and how current students can explore their options.
