C. CSCI-1320, MATH-1312 or MATH-2308, and an upper division MATH or CSCI course approved by the student’s advisor.

D. GEOS-2400 and one course from GEOS-2402GEOS-3402, GEOS-3310.

IV. University requirements

Completion of all other required elements of the Pathways curriculum and at least 120 credit hours. 

Teacher Certification in Biology

Students majoring in biology can receive certification to teach biology in grades 4-8 and grades 8-12. In order to receive certification, students major in biology, complete 11-14 undergraduate hours of education coursework, and complete the Master of Arts in Teaching graduate program at Trinity. After this course of study, students would have a B.S. in Biology, a master’s in teaching, and teacher certification in Texas. For more information and specific requirements, see the Education Department’s program description in the course catalogue.

Guidelines for Acceptance of Majors

Full acceptance in the major is granted if the following requirements are met at the time of application:

  1. Completion of BIOL-1311, BIOL-1111, BIOL-2312, and BIOL-2112 with grades of C- or better in each class.
  2. Completion of CHEM-1311, CHEM-1312, and CHEM-1112 with grades of C- or better in each class.
  3. An overall grade point average of at least 2.0.

Students who do not meet the above criteria may be granted provisional acceptance if it is judged that there is a reasonable expectation they can complete the degree program.

A student may not earn a major in Biology and another major in Biochemistry and Molecular Biology or in Neuroscience.

Honors in Biology 

Biology majors are eligible to enroll in the Honors Program if they satisfy the University requirements that are described elsewhere in this bulletin. During their junior year, honors candidates should identify a faculty mentor and meet with the Department Chair. Completion of the Honors Program includes six hours of research courses (BIOL-4398 and BIOL-4399). Honors candidates must submit to the Department Chair a written proposal to graduate with Honors in Biology prior to starting BIOL-4398. The decision to confer or not to confer honors will be made by the departmental faculty and will be based on the quality of the written thesis and the oral presentation of that thesis.
