Read on to learn more about what it takes to earn this degree and how graduating with an online master's in environmental science can help advance your career.

Why Get a Master's Degree in Environmental Science?

A field as diverse as environmental science attracts a variety of prospective students. Among the most obvious candidates for an online master's in environmental science program are bachelor's-level students seeking career advancement opportunities and students pursuing a specialization in the field that requires additional education. Others who might want to look into this degree include those trying to decide between earning a professional certification or a master's, as well as current professionals interested in furthering their career options and salary potential.

The list below details three key motivations that drive prospective students toward a graduate-level education in environmental science.

Pursuing Specialization

Students may pursue a master's in environmental science online in order to find work in a specialization within the field or to branch out into environmental science specializations in related industries. At the graduate level, degrees often feature concentration components geared toward students with a specialization in mind, such as sustainability science, ecological/environmental management, or conservation. Environmental science professionals requiring specialized education may include sustainability specialists, environmental program directors, and environmental health and safety specialists.

Career Advancement Opportunities

Many entry-level jobs in the environmental science field can be pursued by those with a bachelor's degree alone, including environmental science and protection technicians, soil and water conservationists, and water or wastewater engineers. However, an online master's in environmental science can increase one's competitiveness in the workplace, helping workers secure promotions to jobs with more responsibility and higher pay. Graduate-level education is sufficient for careers as an environmental scientist, environmental engineer, or hydrologist.

Online Learning Technology

Whether developed for synchronous or asynchronous delivery, today's online college experience requires extensive use of computer technology to access coursework, complete assignments, and communicate with peers and professors. Environmental science professionals often need excellent communication and technology skills, in addition to advanced academic knowledge. From this perspective, utilizing the latest communication technology and learning management systems to complete a master's degree online can serve as a useful professional development tool.

Prerequisites for Online Environmental Science Programs

In order to pursue a master's in environmental science online, students typically need to meet several prerequisite requirements. These vary by school/program, they but may include the following:

  • Work Experience: Most online master's degrees in environmental science do not require applicants to supply proof of work experience. Assuming other prerequisite requirements are met, students can typically apply to programs as soon as they earn their bachelor's. However, gaining work experience before beginning a graduate track can prove valuable, allowing students to apply practical knowledge to their studies.
  • Exams and Test Scores: Exam and test score requirements vary from school to school. Not every online master's in environmental science program requires standardized test scores. Schools that do require the GRE do not always advertise their minimum score requirements. However, competitive GRE scores generally include 158-162 on the verbal section and 159-162 on the quantitative section. Scores are valid for five years.
  • Coursework: Students interested in earning a master's in environmental science online typically must have a significant undergraduate history and high GPAs in science and mathematics. Specific requirements vary, but applicants should expect to need at least one semester of calculus, statistics, and chemistry. Many schools have designated completion plans available for strong applicants who lack necessary course prerequisites.
  • Recommendations: Requirements for professional references or letters of recommendation vary from school to school. Some graduate programs do not require any at all. Others may request or require 2-3 recommendations. Letters should be provided by either professors or employers who can speak to an applicant's academic ability, work ethic, and/or integrity.
  • Essays: A majority of online master's degrees in environmental science require submission of an essay during the admissions process. Generally, essays should demonstrate an applicant's best writing abilities, show a compelling interest in environmental science, reveal how the degree aligns with an applicant's career goals, and explain what qualities an applicant would bring to the program.
  • Interviews: Generally, applicants do not need to complete interviews when applying to a master's in environmental science online. However, exceptions may occur, especially for extremely popular programs or competitive cohorts. If required to complete an interview with faculty or admissions staff, applicants should be prepared to discuss their academic and employment histories, relevant accomplishments, and future goals.
  • International Students: International students applying to an online master's in environmental science may need to provide proof of English language proficiency, in addition to all of the other prerequisite requirements. The most popular test choices for English language proficiency are the TOEFL and the IELTS. Students with degrees from schools outside of the U.S. should also closely evaluate course equivalencies.

What to Expect From a Master's-level Online Environmental Science Program

Students earning a master's in environmental science online typically take 30-40 credits of advanced coursework and a capstone project. Most programs are designed for completion in 2-3 years of full-time study (longer for part-time students).
