ALC's Natural Science & Mathematics Goals

The Natural Science and Mathematics Division offers excellent programs of study. In these programs, faculty work with students in the classroom and individually in order to broaden the students’ view of the world. The Natural Science and Mathematics curriculum allows students to study the scientific approach to learning about the natural world using the problem solving and critical thinking techniques associated with the major areas of science and mathematics, including biology, chemistry, mathematics, physics, and statistics. Since the observable world can be viewed from either the macroscopic, microscopic, or atomic viewpoints, students are encouraged to develop their concrete and abstract thinking and reasoning skills. Many graduates of Alice Lloyd College who receive a degree in science further their education by entering programs in medicine, pharmacy, engineering, dentistry, teaching/education, nursing, physical therapy, and so on. It is the desire of the science and mathematics faculty that students develop an appreciation for learning and so become life-long learners.

Students wishing to seek advanced degrees in medicine, dentistry, and pharmacy are encouraged to consider the opportunities available through the Caney Cottage Scholarship Program. This competitive scholarship is available to qualifying students who are accepted into graduate or professional schools.

Also, take a look at our Science and Math Brochure (pdf), which introduces you to some of our standout students and relates their experiences at ALC.

Pre-Professional Programs with Transfer Agreements in Pre-Pharmacy

To assist students transferring from Alice Lloyd College to professional programs in pharmacy, direct transfer agreements have been established with the University of Kentucky and West Virginia University. Students may complete two years of study in Pre-Pharmacy and transfer directly to the chosen university for completion of the appropriate degree in Pharmacy. For further details, please contact the Pre-Pharmacy advisor or the Vice President for Academics/Dean of the College. Students interested in this pre-professional program should establish their program with the designated advisor at the beginning of their studies at Alice Lloyd College
