Environmental Science

Our environmental science licensure program will prepare you to teach the following courses in grades nine to 12 at all levels, including honors and AP:

  • Ecology
  • Environmental science
  • Related science courses

You'll also be able to teach these introductory level classes:

  • Biology
  • Chemistry
  • Earth and space science
  • Physics

The program consists of 36 credits taken over four semesters. If you're an undergraduate student, you'll most likely complete the program during your last two years at NIU, along with your upper-level content classes.

Start Your Application

In order to enter the program, you must be pursuing a bachelor's degree in environmental science with an emphasis in educator licensure at NIU. You're also eligible if you hold a bachelor's degree in a related discipline.

You must also have the following minimum GPA:

  • Undergraduate: cumulative GPA of at least 2.50.
  • Graduate: cumulative GPA of at least 3.00.
  • GPA in all science and math courses must be at least 2.70.

You must complete the following requirements to earn your professional educator licensure with an endorsement in environmental science.


During your clinical placements, you'll complete a minimum of 100 hours of observations in at least three different high school classrooms in the northern Illinois region.

Subject Matter Test

You must successfully pass the Illinois Licensure Testing System (ILTS) content test in environmental science (112) before student teaching.

EdTPA (Teacher Performance Assessment)

You must successfully pass the edTPA during student teaching in order to receive an Illinois teaching license.

Criminal Background Checks

The schools at which you complete your clinicals may require a criminal background check. You will learn how to complete this in your clinical classes.

Health Checks

You must pass a TB test prior to your third semester in the program. TB tests are available for free to NIU students at Health Services and are good for one year.

Required Coursework

In order to earn your license, you must complete all required courses with a grade of C- or better. If you earn a D or F, you must repeat the course.

Contact us for guidance on course requirements if you are a transfer student or if you already earned a bachelor's degree in a related discipline.

You can read detailed descriptions of the following required courses in the NIU catalog. Equivalent courses from other accredited institutions may be substituted at the discretion of the certification advisor.

You may have some flexibility in your courses, as long as selections meet the requirements for environmental science educator certification.
