Selecting the right bachelor's degree in environmental science depends on a number of factors, including program length, quality, location, and cost. Whether you choose a campus-based program or an online environmental science degree, do your homework. Most bachelor's degrees require four years of full-time study. Part-time attendance or distance learning may appeal to students with employment or family obligations who need flexible schedules. Graduation requirements, such as an internship or fieldwork, may increase the time needed to complete the degree. Many environmental science degrees also require laboratory work, research projects, or a capstone course.

Almost all schools that offer an environmental science bachelor's degree have received national or regional accreditation; additionally, some programs have been awarded a programmatic accreditation in specialized areas (see below). Students should look for programs that align with their interests and career goals, and review any available specializations such as sustainability, wildlife management, or environmental policy.

The cost of an environmental science degree varies widely by type of program and school location. In general, public schools cost less than private institutions. Be sure you apply for Free Application for Federal Student Aid (FAFSA) to learn more about financial aid opportunities, work-study, and other on-campus and off-campus jobs. Students should also consider cost-of-living expenses (e.g., food and housing) in addition to what they must spend on tuition, books, and supplies.

Students commuting to campus must budget for transportation costs -- including gas and vehicle maintenance -- or bus, train, or airfares. Some online bachelor's in environmental science programs may also charge supplemental technology fees, or require students to travel to on-campus residencies a few times a year to supplement their web-based coursework.

Programmatic Accreditation for Bachelor's in Environmental Science Programs

A regionally or nationally accredited school has undergone an extensive evaluation by an independent agency to ensure its overall educational quality. Most colleges and universities that offer environmental science degrees have received regional accreditation. Meanwhile, schools with lower tuition, less restrictive admissions, and who offer predominantly vocational or distance-learning course options may hold national accreditation.

Some environmental science degree programs within a regionally accredited institution hold specialized, programmatic accreditations. The National Environmental Health Science and Protection Accreditation Council (EHAC) describes itself as the only programmatic accreditation agency specific to environmental science programs. Forestry science programs at the bachelor's and master's level may apply for specialized accreditation from the Society of American Foresters. The Accreditation Board for Engineering and Technology (ABET) administers programmatic accreditation in several areas related to environmental science, including engineering, technology, applied science, and computer science.

Graduates of programs that feature these kinds of specialized accreditations can benefit from faster career advancement, increased salaries, and improved chances for graduate school admission.

Each school that offers a bachelor's degree in environmental science establishes its own admission requirements. Traditional programs place considerable weight on academic performance, looking at factors like a student's GPA, and SAT or ACT scores. Because online programs often attract working professionals or those trying to earn a degree while juggling family commitments, their admissions policies may consider life experiences acquired since high school graduation, and give less emphasis to standardized tests and grades.

While most schools set application deadlines for February, online programs may offer rolling admissions throughout the year. Students who plan to attend a traditional brick-and-mortar college can begin applying as early as the summer after their junior year. As a general strategy, students should decide on a couple of “target schools” where they really want to attend, and are likely to gain admission. They should also select a few “safety schools” where they feel their chances for admission are high, and one or two “reach schools” that they would like to attend but may not be competitive enough to get into the acceptance pool.


  • Minimum GPA: Most schools require a GPA of 3.0 out of a 4.0 scale, with some programs establishing a 3.5 minimum. Schools may sometimes consider applicants with lower grades or look for steady improvement from ninth grade through senior year.

Admission Materials

  • Application: Filling out college applications can be time-consuming, but the CommonApp makes this process more manageable. Students using CommonApp fill out one form to apply to any of their 750 member schools.
  • Transcripts: Almost every college wants a stamped, official transcript of high school grades submitted with an application, which shows your GPA and courses taken each term. Some high schools charge a small fee for mailing these transcripts.
  • Letters of Recommendation: Some colleges may require as many as three letters of recommendations. Ask your recommenders well before the application deadline, and choose teachers or advisors who know you well and will describe you in ways that make you stand out.
  • Test Scores: Some schools consider SAT or ACT scores as one of many factors in their admission decision, along with grades, co-curricular activities, and recommendations. Most schools do not require a minimum cutoff test score.
  • Application Fee: Students can expect to pay an average of $40 for each application. Some schools charge more, while others may not ask for any fees. Schools may waive application fees for students who document financial hardship.

Most environmental science degrees consist of courses in geology, chemistry, ecology, and other foundational subject areas; however, the curricula, specializations, and graduation requirements differ for each school and program. Graduation requirements may include capstone courses or research projects, and many programs feature fieldwork or internships for students to apply their academic training in real-world settings.
