 Areas of Concentration

For the ENSC degree, all students must have an area of concentration in a Natural Science department.  For departments other than this one, the requirement is 17-19 credit hours of course work.  Most ENSC majors elect one of the two concentrations within the Department for their concentration (biology or geology), but a number of concentrations are available:

  Biology Concentration

CHEM 3810 and 4200
EEES 2015 and 2200

 Other Concentrations

Other concentration tracks are also available, such as in Physics, Mathematics, or Astronomy; however, few students opt for these. If interested, contact your advisor.


All students majoring in ENSC participate in environment-related projects with a government agency, University laboratory, private corporation, non-profit organization, or other approved sponsor.  This experience must last for at least 100 hours, and must be approved in advance by the internship coordinator, Dr. Sigler.  A written report on the internship is required.   Up to 3 hours of course credit may be granted for the internship by enrolling in EEES 4940 (internship); however, credits earned in this way may not be substituted for required courses in the area of concentration.  This requirement may be fulfilled at any time prior to graduation.

 Exchange Program

Students with strong academic records may wish to participate in our exchange program with the University of Hertfordshire (England) or with the University of Salford by spending their junior year studying abroad. Courses taken there transfer back to Toledo, and students graduate on schedule. Hertfordshire is one of only twelve Environmental Science programs in the United Kingdom receiving a rating of "excellent" by their accrediting agency.
