Student Learning Outcomes
The Doctorate in Forestry prepares students as academic professionals, scientists and policy specialists for government and non-governmental agencies and organizations by providing extensive study in the area of Forestry and the development of original scientific research through the completion of the dissertation.
Students work closely with their advisor and to create a course of study wherein they achieve the following competencies:
- First-hand experience with the full range of activities that generate scientific knowledge; expert knowledge about a specific research topic; ability to acquire expert knowledge for new and emerging topics; ability to make novel contributions to scientific understanding through original scientific research; clear, concise oral and written communication; critical thinking; effective teaching.
- An expert understanding of fundamental knowledge about forest ecosystems and human management of forests by placing their scholarship into the broad context of subject knowledge in forestry and forest management
- Expert knowledge about a specific research topic in Forestry, including its major theories, controversies, methods of inquiry, theoretical and methodological challenges, connections with related disciplines, leading edges, and applications to advancing forest management.
- A thorough understanding of research ethics, particularly the ability to examine how ethical issues impact decisions concerning research design, and applying this knowledge to develop ethical approaches to research methodology and data collection.
- Skills and ability to make significant and novel advancements in scientific understanding of forest ecosystems and human management of forests through designing an original research study of personal or professional interest and importance including: planning, organizing, scheduling, and executing the project.
- Expertise with research methods used in Forestry, particularly the modes of inquiry and quantitative methods appropriate to the area of their dissertation. Identifies and defines appropriate variables and methods of data collection for the dissertation, and analyzes, interprets and explains research findings. Evaluates the effectiveness of the project and its implications to the field of forestry.
- Expert communication in oral presentations, writing, and using posters to scientists, forestry professionals, and the general public about the student’s dissertation research and topic. In addition, conducts a dissertation defense to a community of forestry faculty.

Research Competency Requirement
Northern Arizona University policy for Ph.D. programs includes a Research Competency requirement that must be satisfied before a student can be admitted to candidacy. In most departments, this is enforced as a requirement to demonstrate an ability to translate disciplinary literature from a foreign language into English. The School of Forestry has chosen to recognize FOR 690, STA 570 (or equivalent), plus one graduate-level course with significant content in statistics, as meeting this requirement.
