All PhD-CS students are required to demonstrate competency in these areas:
Computer Competency — Doctoral students are required to have the computer skills necessary for completing a dissertation. Students must be able to prepare documents using advanced word processing skills (e.g., creation of tables and figures, headers and footers, page breaks, tables of contents, hanging indents). Students must use computer programs for the statistical analysis of data (e.g., SAS). Students must produce a computer-based presentation (e.g., PowerPoint) for their dissertation oral examination.
The faculty assists each Doctoral student in reaching this high goal through a systematic process that leads to a high-quality completed dissertation. A PhD dissertation is a scholarly documentation of research that makes an original contribution to the field of study. This process requires care in choosing a topic, documenting its importance, planning the methodology, and conducting the research. These activities lead smoothly into the writing and oral presentation of the dissertation.
A doctoral candidate must be continuously enrolled throughout the series of dissertation courses. Dissertation courses are automatically scheduled and accepted without breaks to ensure that students remain in continuous enrollment throughout the dissertation course sequence. If additional time is required to complete any of the dissertation courses, students must re-enroll and pay the tuition for that course. Continuous enrollment will only be permitted when students demonstrate progress toward completing dissertation requirements. The Dissertation Committee determines progress.
The University’s mission is dedicated to assisting students in achieving their academic aspirations and helping them become valuable contributors to their community and profession. To support our mission, the University now offers a dissertation completion pathway for students who have completed their doctoral coursework and achieved doctoral candidacy at a previous institution but were unable to complete their dissertation. The University’s Dissertation Completion Pathway (DCP) offers a unique opportunity for students to complete their doctorate in one of the doctoral programs offered at the University (excluding the PhD-MFT and DNP). Students successfully meeting the entrance and application requirements will complete a minimum of 23 credit hours to earn their doctorate.
Vision
The vision for the Dissertation Completion Pathway is to provide “all-but-dissertation” or ABD students with a structured plan to complete their dissertations and achieve their academic goals of earning a doctorate. This pathway offers a student-centered, high-touch approach that acknowledges previous academic coursework while offering the preparation and guidance needed to earn their doctoral degree.
Basis for Admissions
- Must have completed all required doctoral program coursework and/or achieved doctoral candidacy from a regionally-accredited institution;
- A previous doctoral program must academically align with a degree program and specialization offered by the University (excluding PhD-MFT and DNP).
- 7-year maximum for block transfer of credits into an existing University degree program (from official transcripts). Credits aged between 8 and 15 years can be accepted as an exception to the policy, with Dean approval.
- Minimum GPA of 3.0 in previous doctoral program coursework.
- Complete the Enrollment Application for the DCP, including all required documents and acknowledgments.
- Cannot be academically dismissed from a previous doctoral program.
- Completion of a memorandum of understanding and statement of intent.
General Pathway Requirements
The DCP can be completed with a minimum of 23 credit hours, but may require additional credit hours, depending on the time required to complete the dissertation research. If needed, further courses will be added to the student’s degree program in alignment with the SAP and Academic Maximum Time to Completion policies. Students who do not complete their program in accordance with these policies may be dismissed.
Dissertation Completion Pathway students must achieve the following general requirements:
- The DCP requires the successful completion of a minimum of 23 semester credit hours.
- Grade Point Average of “B,” 3.0, or higher must be maintained throughout the DCP.
- Official transcripts on file for all transfer credit hours accepted by the University.
- Official documents on file for the basis of admission.
- All financial obligations must be fulfilled before the student will be awarded their diploma.
The DCP is a structured pathway that recognizes past academic coursework while providing the guidance needed to complete a doctoral degree. This pathway includes DCP bridge courses explicitly designed to support ABD students before entering the doctoral prospectus course and the dissertation courses. *If the deliverables are not met in a particular dissertation course, continuation courses (B, C, and D) may be required.

A doctoral candidate must be continuously enrolled throughout the series of dissertation courses. Dissertation courses are automatically scheduled and accepted without a break in scheduling to ensure that students remain in continuous enrollment throughout the dissertation course sequence. If additional time is required to complete any of the dissertation courses, students must re-enroll and pay the tuition for that course. Continuous enrollment will only be permitted when students demonstrate progress toward completing dissertation requirements. The Dissertation Committee determines progress.
Program Disclosure
Successful completion and attainment of National University degrees do not lead to automatic or immediate licensure, employment, or certification in any state/country. The University cannot guarantee that any professional organization or business will accept a graduate’s application to sit for any certification, licensure, or related exam for the purpose of professional certification.
Program availability varies by state. Many disciplines, professions, and jobs require disclosure of an individual’s criminal history, and a variety of states require background checks to apply to, or be eligible for, certain certificates, registrations, and licenses. Existence of a criminal history may also subject an individual to denial of an initial application for a certificate, registration, or license and/or result in the revocation or suspension of an existing certificate, registration, or license. Requirements can vary by state, occupation, and/or licensing authority.
NU graduates will be subject to additional requirements on a program, certification/licensure, employment, and state-by-state basis that can include one or more of the following items: internships, practicum experience, additional coursework, exams, tests, drug testing, earning an additional degree, and/or other training/education requirements.
All prospective students are advised to review employment, certification, and/or licensure requirements in their state, and to contact the certification/licensing body of the state and/or country where they intend to obtain certification/licensure to verify that these courses/programs qualify in that state/country, prior to enrolling. Prospective students are also advised to regularly review the state’s/country’s policies and procedures relating to certification/licensure, as those policies are subject to change.
National University degrees do not guarantee employment or salary of any kind. Prospective students are strongly encouraged to review desired job positions to review degrees, education, and/or training required to apply for desired positions. Prospective students should monitor these positions as requirements, salary, and other relevant factors can change over time.
