Diné College’s Associate of Science Degree in Mathematics is designed to provide students with the opportunity to acquire skills and knowledge that include the ability to apply mathematical principles competently, think critically and creatively, understand abstract concepts, and use technology to ensure the well-being of the Diné People.

The Science and Physical Education Division at Diné College teaches a BS in Biology degree and a BS in Secondary Education, Science (Biology) tract, degree. We also teach six Associate of Science degrees and four Certificates.

The Bachelor of Science in Biology degree is designed to promote enhanced knowledge and appreciation of life on earth while also providing courses and training that will enable students to succeed in academics, develop a career path, pursue graduate studies, obtain employment and promotion in the workforce, and serve the Navajo Nation. The degree is a total of 122-128 credits, with a minimum of 46 hours in Biology including required courses in vertebrate and invertebrate zoology, ecology, cell biology, evolutionary biology, plant and animal taxonomy, and climate studies. In addition, students will develop broader skills with 27 hours in math, chemistry, and physics, and 42-44 hours of general education courses. Our own summer intern programs in public health and biology are also available to enhance student learning and build contacts with employers on the Navajo Nation.

The Bachelor of Science in Secondary Education, Science track, taught jointly by us and the Center for Diné Teacher Education, is a dual major of education and biology that prepares students to be certified to teach high school biology or other high school sciences, especially on the Reservation, where these teachers are in high demand.

Our six Associate of Science degrees (Biology, General Science, Health Occupation, Environmental Science, Agroecology, and Public Health) allow students to transfer to a four year program or vocational training, while also providing adequate background for many areas of employment.

The AS and four BS in Biological Sciences promotes enhanced knowledge and appreciation of life and of living organisms on earth. Environmental Sciences prepares students for transferring to a Bachelor of Science degree program in Environmental Science, Environmental Management, Environmental Studies, or Science Education for grades 7 through 12. It can be modified for transferring to a B.S. program in other natural science disciplines. The program meets the requirements for Arizona’s General Education Science requirements. The Public Health program is designed for working health professionals as well as those wishing to pursue a health profession that emphasized community and population health. It promotes Navajo concepts of health and wellness. The A.S. in Public Health is either a terminal degree or transfer program to colleges and universities that offer four year programs in public health, health education, health promotion, or community health. The program offers two options: the Health Education (Socio-Cultural) Option and the Environmental Public Health Option.

Certificates in Irrigation Technology, Natural Resources, and Public Health further students abilities and training for many job opportunities, and provide a foundation for additional education and employment options.
