Biological Sciences

The Department of Biological Sciences offers two distinct four-year curricula that lead to the baccalaureate degree. These are the Bachelor of Science in Biology and the Bachelor of Science in Biomedical Science. In addition, Pre-Health professional programs are offered which include Pre-Medicine, Pre-Dentistry, Pre-Physical Therapy, Pre-Pharmacy, and Pre-Veterinary Medicine. Secondary teaching certificates may be obtained with Science Certification or Life Science Certification. The curricula are designed to maximize career opportunities and to prepare students for various graduate and professional school programs.

A Master of Science degree is also offered. For further information, see the graduate section of this catalog.

Important Information Regarding Health Professions Programs

The Pre-Medical/Pre-Dental, Pre-Physical Therapy, and Pre-Veterinary Support Areas in Biomedical Science are designed to meet or exceed the entrance requirements for medical, dental, physical therapy, and veterinary programs in Texas. Other health profession programs including, but not limited to Physician Assistant, Pharmacy, Optometry, Chiropractic, Podiatry, Radiology Technician, and Dental Hygiene can vary considerably in terms of entrance requirements. Students interested in such programs are encouraged to earn a BS in Biomedical Science by following the General Biomedical Science Support Area. By allowing greater flexibility in elective courses, the General Biomedical Science Support Area can be easily adjusted to meet the entrance requirements of these health profession programs.

A program in Pre-Veterinary Medicine is also offered through the Department of Animal Science and Wildlife Management. Although the Pre-Veterinary programs offered through the Departments of Animal Science and Wildlife Management, and Biological Sciences each meet all the requirements for admission to the Texas A&M College of Veterinary Medicine, a student is typically best suited for one program or the other. It is important that a student discuss with an advisor which program is best suited to his or her interests, skills, and goals.

It is important to know that health profession programs may change entrance requirements without notice. Therefore, it is the responsibility of the student to check these requirements and work closely with an advisor to ensure that all requirements are met. If all of the entrance requirements for a professional program have been met, it is sometimes possible for a student to matriculate to the professional program prior to completing a degree at Tarleton. In this case, a student might meet the requirements of a Bachelor of Science degree at Tarleton by

  1. fulfilling the “Degree Requirements” as stated in the Academic Information section of the catalog and
  2. transferring the necessary hours from an approved professional school to Tarleton for a minimum total of 120 hours.
