The Diploma in Liberal Studies (DLS) is a selective post-master’s program designed for intellectually motivated adult learners pursuing advanced interdisciplinary study beyond the Master of Interdisciplinary Studies (MIS) or a similar graduate liberal studies degree. The program offers students the opportunity to deepen their expertise in two academic focus disciplines, refine their interdisciplinary research skills, and complete a substantial independent thesis or project.

While rooted in the liberal arts, the DLS is tailored for working professionals, retirees, and other non-traditional university students who wish to expand their academic foundation through graduate-level inquiry. Courses are taught by distinguished Rice faculty and select visiting scholars, maintaining the university's high academic standards.

The program welcomes non-MIS students on a case-by-case basis, based on prior academic preparation and future intellectual goals. Well-prepared applicants accepted into the program benefit from advanced coursework, faculty mentorship, and the opportunity to contribute meaningfully to academic and public discourse, whether through research, teaching, writing, community engagement, or professional practice.

The Diploma in Liberal Studies (DLS) builds upon the multidisciplinary foundation of the MIS or similar graduate liberal studies programs by offering students the opportunity to deepen their academic expertise in three key ways:

1. Deepen Disciplinary Knowledge
   Students pursue focused study in two academic disciplines—completing three advanced graduate courses in each focus area—to build depth alongside interdisciplinary breadth.
   
2. Advance Interdisciplinary Research Skills
   Through coursework and faculty mentorship, students develop their ability to synthesize ideas, methods, and frameworks across disciplines, emphasizing integrative, research-based learning.
   
3. Produce Original, Integrative Work
   Students apply their disciplinary and interdisciplinary learning to complete a substantial Diploma Project or Thesis in their final two terms. This independent work reflects both academic rigor and creative synthesis, allowing students to generate new insights and contribute meaningfully to scholarly or professional discourse.
