1. Prior Education:
* Bachelor's Degree: A bachelor's degree in a relevant science field (e.g., environmental science, biology, chemistry, geology, ecology) is essential. A strong GPA is typically required.
* Master's Degree: Many, but not all, ScD programs require a master's degree. Some programs allow highly qualified candidates with exceptional undergraduate records to enter directly into the doctoral program. A master's thesis demonstrating research aptitude is often beneficial.
2. Admission Requirements:
* GRE Scores: Some programs may still require GRE scores (General and possibly Subject tests), though this is becoming less common.
* Letters of Recommendation: Strong letters of recommendation from professors or researchers familiar with your academic capabilities and research potential are crucial.
* Statement of Purpose: A well-written statement outlining your research interests, career goals, and fit with the program is vital. It should clearly demonstrate your understanding of environmental science and your commitment to research.
* Research Experience: Prior research experience, ideally demonstrated through publications or presentations, is highly valued. This could be from undergraduate or master's level work.
3. Program Requirements:
* Coursework: A core curriculum covering fundamental aspects of environmental science (e.g., ecology, toxicology, hydrology, atmospheric science, environmental policy) and specialized coursework related to your chosen research area.
* Comprehensive Exams: Most programs require comprehensive exams to demonstrate mastery of core concepts.
* Dissertation Research: The most significant component. This involves conducting original, substantial research in a specific area of environmental science, culminating in a substantial dissertation. This requires developing a research proposal, collecting and analyzing data, and writing a comprehensive dissertation that contributes new knowledge to the field. This often takes several years.
* Dissertation Defense: A formal oral defense of the dissertation in front of a committee of faculty members.
* Publications: Publication of research findings in peer-reviewed journals is highly encouraged and sometimes a requirement for graduation.
* Presentations: Presenting research findings at conferences and seminars is often expected.
4. Funding:
* Financial Aid: Many ScD programs offer funding opportunities such as teaching assistantships, research assistantships, and fellowships. Securing funding is often a necessary part of the application process.
It's crucial to consult the specific requirements of each university's environmental science ScD program. These programs can vary substantially in their emphasis (e.g., more policy-focused vs. more science-focused), curriculum, and admission criteria. Check the websites of universities offering ScD programs in environmental science for the most accurate and up-to-date information.
