Description

The Biology Program offers a major and a minor to students in the Weekday Program; several courses are offered for non-majors. In conjunction with various other programs, the Biology Program also supports interdisciplinary majors in biochemistry and environmental science as well as a minor in bioethics. Biology majors and minors pursue a diversified program that fulfills a breadth of interests and ultimately prepares them to pursue careers in many areas of the biological sciences, including education, research, and medicine. For those in related majors, the goal of the program is to focus particularly on the interfaces between biology and their major disciplines. Non-majors who take biology courses receive an exposure to biologyto its fundamental concepts, latest discoveries, and modes of inquiryin ways that are relevant to their personal and professional lives and consistent with the objectives of the Foundation for Leadership Curriculum. Extraordinary developments in modern biology offer much to engage students at all levels.

Trinity offers biology students the advantages of close faculty-student relationships while providing access to the country's primary resource collections, major research facilities, and outstanding internship opportunities at nationally recognized facilities.

Bioethics

A student wishing to develop the value and policy dimensions of basic biological knowledge and practical applications may follow a minor in bioethics; see Philosophy Program for requirements.

Neuroscience

While neuroscience is not offered as an official minor, students wishing to prepare for graduate study in this rapidly growing discipline are advised to major in either biology or psychology and minor in the other. A student should consult with her or his advisor in order to make a judicious selection of courses in biology, chemistry, and psychology.

Program Policies

Advanced Placement: Credit will be granted for the score of 4 or 5 on the AP examination. A score of 4 or 5 will be accepted in lieu of BIO 151.
CLEP Policy: A satisfactory score on the CLEP examination in general biology will be accepted in lieu of BIO 151.
Grades in Major Courses: Students are required to earn a grade of "C" (2.0) or better in all courses counted to fulfill requirements for the major.
Pass/No Pass: Courses fulfilling the major requirement may not be taken pass/no pass.
Senior Assessment: The senior assessment in biology consists of a written exam drawn from a set of comprehensive study questions and a one-hour oral exam.
TELL Policy: TELL credits do not count towards the major in biology.
Transfer Credits: Transfer credit will be awarded after appropriate program review and approval.
