Frequently Asked Questions

Is an online Master’s degree in Environmental Science worth it?

For students who want to expand their learning and career opportunities, a master’s degree in environmental science is a good consideration. In terms of career prospects, the job outlook for environmental scientists and specialists looks good. It is projected to grow by 6% between 2022 to 2032, as fast as average.

The value of environmental education goes beyond career advancement as environmental issues are becoming a major concern not only in the country but also on the global scale. Those who take this major for their advanced degree often have greater aims for the good of the environment as they seek to develop the necessary knowledge and skills that can aid environmental risk assessment and provide solutions to the most pressing problems.

What’s the timeline for completing an Environmental Science online Master’s program?

A master’s degree often requires more focus on research, so it means a more rigorous curriculum with advanced courses.

Online students may need to complete a thesis by the end of the program, which can impact the overall program duration. Usually, the environmental science master’s programs can take two years to complete, provided students are enrolled full-time. Part-time students may need more time to finish the coursework and earn the degree.

Still, there are environmental science programs that offer accelerated learning formats. This allows online students to complete the degree quicker than average students. Ultimately, the length of time it takes for one to earn their master’s degree generally varies depending on the university they have enrolled in.

What are the common admission requirements for the online Master’s program in Environmental Science?

The admission criteria for environmental science master’s programs often depend on the university. Some are competitive and include requirements such as GRE test scores and a minimum GPA.

Others may only require interested graduate students to hold a bachelor’s degree along with the submission of other requirements such as letters of recommendation, personal statements, resumes, demonstrated work experience in the relevant field, and more.

To be sure, online students have to check with the specific university they are planning to enroll in so they can verify the correct admission requirements.

How much does a Master’s degree in Environmental Science cost?

There is a wide variance between universities and colleges when it comes to their own total cost structures, so a good starting point would be to take the typical per-credit-hour cost multiplied by the number of credit hours for the program.

In this case, online master’s in environmental science degree programs typically range between $600-$700 per credit hour, with some universities costing less and some nearing the $1000 per credit hour range. Typical environmental science master’s degree programs hover around 30 credit hours in total.

Overall, it is best to consult directly with individual universities to get the most accurate cost figures. Some of them may also offer tailored payment plans for individual students. Most importantly, they would also offer their own set of financial aid opportunities like scholarships, grants, and special discounts that go into offsetting total costs on top of the standard federal student aid.

Key Takeaways

Environmental Science degrees are necessarily interdisciplinary in terms of their course content and curriculum design since environmental challenges tend to require multiple skill sets and involve various fields and disciplines in coming up with effective plans that prevent and mitigate their effects.

The interdisciplinary nature of environmental science degree programs typically sees curriculum designs that teach skillsets related to research and data analysis but also content covering social science and socio-economic aspects, as well as content dealing with advocacy and policy.

The various interconnected effects of climate change and other environmental problems continue to be felt by the whole world in many ways, and the level of awareness of communities, institutions, and organizations also continues to increase. This translates to a projected overall increase in the demand for professionals in the field of environmental sciences to address these needs.
