One type of doctoral program that traditionally requires the completion of a dissertation is a Doctor of Philosophy (PhD) program. PhD programs are research-focused doctoral degrees that are designed to produce scholars in a particular academic discipline or professional field. The overarching goal of PhD study is to contribute new knowledge and understanding to the field through original research. For this reason, completing a dissertation is a core requirement of most PhD programs.

The dissertation is the culminating project of a PhD program where students conduct extensive independent research and scholarly work under the supervision of faculty advisors and dissertation committee members. Through the dissertation, PhD candidates demonstrate their ability to identify a research problem or question within their field of study, conduct a comprehensive review of relevant literature, utilize appropriate research methods and analysis, and make an original contribution to the body of knowledge in the discipline. Dissertations generally take 1-3 years of full-time work to complete after coursework is finished.

The dissertation process consists of several formal steps. Students first develop a dissertation proposal outlining their research question or hypothesis, literature review, methodology, and anticipated findings. This proposal must be approved by the student’s dissertation committee before research can begin. Once approved, students move forward with conducting the proposed research and analysis. Throughout this stage, regular meetings are held with advisors to discuss progress and receive guidance.

Upon completion of the research and analysis, students write a lengthy dissertation manuscript presenting all elements of the completed research project. The written dissertation typically ranges from 150-300 pages in length and includes an introduction, literature review, methodology section, results/findings, discussion/conclusion, and references. After the written dissertation is submitted, students must then defend their work orally during a dissertation defense meeting with their committee. The committee will ask questions and evaluate the quality and rigor of the student’s independent research and written work.

Upon passing the defense, making any required revisions or corrections, and gaining final approval from the dissertation committee and graduate school, the PhD candidate will have completed all requirements for the doctoral degree. The dissertation demonstrates to degree granting institutions that PhD graduates have reached the level of expertise required to independently and creatively conduct worthwhile, publishable research within their specialized field of study. It is considered a hallmark of PhD education and signifies that a student has achieved a distinct level of expertise beyond a master’s degree.

There are many specific PhD programs across various disciplines that require completion of a dissertation as the capstone project. Some common examples of doctoral programs requiring a dissertation include PhD degrees in various sciences like Chemistry, Biology, and Physics. In the social sciences fields, programs such as Psychology, Sociology, Political Science, and Economics all typically require an original dissertation as the culminating experience. Dissertations are also standard components of PhD degrees in many humanities fields including Philosophy, History, English, and Communications. Professionally-oriented PhD programs in areas like Education, Nursing, Social Work and Business also generally necessitate completion of an independent research dissertation on a specialized topic within the given professional domain.

While dissertation requirements and formats vary some between individual doctoral programs and research topics, the multi-step process of developing a proposal, independently conducting original research using accepted methods, writing a lengthy manuscript, and defending the work publicly remains consistent across most academic PhD programs in the United States. The dissertation allows emerging scholars to make an authentic research-based contribution to their specialized field of study under the guidance of faculty experts before earning their doctoral degree. It is truly the pinnacle requirement demonstrating a student’s readiness to independently contribute to their discipline at the highest level as a credentialed PhD.

A dissertation is the defining component of most PhD programs across various academic disciplines in the United States. Through the rigorous multi-stage process of developing, conducting, writing, and publicly defending a substantial piece of original research, doctoral students complete the most complex and career-defining project of their education. Earning a PhD through successful dissertation work signifies that a graduate has reached the peak of expertise in their specialized academic or professional domain and is prepared to independently further advance their narrow field of study through future scholarship and research. The all-encompassing dissertation experience is truly the hallmark final step separating master’s and PhD education.

The capstone project is the culminating academic experience for Walden University’s doctoral students. It represents the application of their knowledge and skills developed throughout their degree program. There are a few different capstone options that Walden students can choose from depending on their specific doctoral program.

For most programs, the default capstone is the doctoral dissertation. The dissertation process at Walden is structured to help students complete an original research study that contributes new knowledge and understanding to their field of study. Students work closely with a dissertation chair and committee to define their topic, conduct a thorough literature review, obtain necessary approvals, collect and analyze data, and write, edit, and finalize their dissertation. The dissertation demonstrates a student’s ability to design and implement an independent, scholarly research study according to approved standards.

Some doctoral programs, such as the Doctor of Nursing Practice and Doctor of Social Work programs, have a professional capstone project instead of a dissertation. In these programs, the capstone focuses on solving a practical problem or creating a program, product, or system in the student’s area of specialization. Capstones in practice-focused programs typically involve a needs assessment, proposal for a new program or intervention, implementation and evaluation plan, or similar applied research project.

Regardless of format, all Walden capstones must meet rigorous research and writing standards. They involve applying appropriate research methodology, designing effective evaluation plans, adhering to ethical standards, obtaining necessary approvals, contributing original analysis and insights, and effectively communicating the study, project details, processes, findings, and conclusions in a scholarly written report. The quality and rigor of the capstone demonstrates that students have mastered advanced research skills and can independently conduct significant work that expands the body of knowledge in their discipline.

Students work closely with a dedicated capstone chair or committee throughout the entire capstone process. This includes the initial capstone proposal phase where they develop their problem statement, purpose statement, central research question or project goal, conceptual framework, and detailed methodology. Committees provide guidance on these foundational components to help set students up for success.

After the proposal is approved, students then enter the implementation phase where they carry out the approved research plan or project activities. Throughout data collection, analysis, and initial drafting of the final report, regular meetings with the chair/committee ensure appropriate progress is being made. Chairs are also available on an ongoing basis for guidance, feedback on drafts, and support.

The final capstone document follows specific formatting guidelines in adherence with standard dissertation or final project report standards. In the dissertation, this includes adhering to established sections such as introduction, literature review, methodology, findings, conclusions, etc. For other capstones, there may be similar or modified required sections. The final written product represents the original work in its entirety for review by the committee.

When complete, the capstone culminates in an oral defense/presentation. In a dissertation defense, students orally present on and answer questions about all aspects of their study from the committee. Other capstones may involve a final presentation and questions or a culminating project evaluation meeting.

Upon successful completion of all required components and oral defense or evaluation, students have completed their capstone requirement and are cleared to graduate from their doctoral program once any final formatting requirements or revisions are also complete. The capstone demonstrates their mastery of research skills and content knowledge in their field, preparing them for professional research, scholarship, practice, and career advancement at the doctoral level.

The doctoral capstone at Walden University is a rigorous culminating project designed to allow students to integrate their learning through independent applied research or a major project. It demonstrates research and writing skills as well as content mastery in the program of study. Completion of the capstone is the final requirement prior to graduating with a research-focused doctoral degree.

WHAT ARE SOME EXAMPLES OF CAPSTONE PROJECTS THAT STUDENTS HAVE COMPLETED IN DOCTORAL PROGRAMS

Leave a reply

Doctoral capstone projects take on many forms depending on the specific program and discipline. Some common types of capstone projects for PhD and professional doctorate programs include dissertations, theses, major research papers, comprehensive exams, portfolios, and practicum projects. Here are some representative examples of capstone projects across different fields to illustrate the depth and rigor required at the doctoral level:

In education PhD programs, candidates often complete major action research projects as their capstone. One such project analyzed how instructional practices in undergraduate statistics courses could be improved to better support student learning and achievement, especially for minority and first-generation students. The scholar conducted a comprehensive literature review on evidence-based teaching methods, designed and carried out her own quasi-experimental study comparing two different approaches over two semesters, and analyzed the resulting student assessment data. Her dissertation provided recommendations for updating the statistics curriculum based on her findings to enhance student outcomes.

In clinical psychology doctorates, the capstone typically involves an original research dissertation. One dissertation from a PsyD program explored correlations between early childhood trauma exposure and likelihood of developing certain mental health disorders later in life. The student utilized a large dataset from an ongoing longitudinal study and performed multivariate statistical analyses to investigate relationships between Adverse Childhood Experiences (ACEs) scores and later diagnoses of PTSD, depression, and substance use disorders. Her novel dissertation advanced understanding of long-term impacts of childhood adversity and informed clinical approaches to trauma-informed care.

For engineering PhDs, the capstone regularly takes the form of sponsored industrial research. One such project was completed in collaboration with a major aerospace manufacturer. The goal was to develop and test new composite materials that could withstand higher temperatures for use in next-generation jet engine components. The candidate designed and 3D printed test samples with various fiber architectures and resin formulations, subjected them to fatigue testing at escalating heat levels, and used microscopic analysis to examine how material structures degraded over time and failure points. Her detailed final thesis provided the sponsoring company with validated data to inform commercialization of stronger, lighter composites.

In nursing doctorates, the capstone usually involves implementation of an evidence-based practice change initiative. One DNP student worked with a large hospital to reduce surgical site infections (SSIs) among high-risk cardiac patients. Through a comprehensive program evaluation, she identified gaps in existing pre- and post-operative SSI prevention protocols. Her project entailed developing standardized best practices, an intensive nurse education program, and updated screening tools to ensure compliance. Rigorous pre- and post-intervention data collection and analysis demonstrated that her evidence-based process improvements led to a 30% reduction in SSIs in the target patient group.

Professional doctorates in business often feature a practicum focused on solving an organizational problem. For example, one DBA candidate partnered with a mid-sized manufacturing firm struggling with low employee retention, especially among millennial workers. Through surveys, interviews and focus groups, he performed a detailed assessment of factors driving turnover. His capstone described implementation of a comprehensive talent management strategy informed by his findings. This included revamped recruiting, onboarding and mentorship programs, as well as flexible benefits, tuition reimbursement, and leadership development initiatives. Six-month post-implementation data showed retention rates had risen 15% overall and doubled among younger employees.

Across fields, strong doctoral capstones showcase candidates’ mastery of advanced research skills and subject matter expertise. By tackling real-world problems, implementing evidence-based solutions, and rigorously evaluating outcomes, these projects demonstrate the independent investigative abilities and practical problem-solving competencies expected of terminal degree recipients. The depth and scale of analysis in the examples shared here exemplify the extensive original work required to earn a PhD or professional doctorate.
