Education Dissertation Defense Questions: What Committees Ask EdD and PhD Candidates

Walk me through your theoretical framework. Why this one, and not a plausible alternative?

Name the framework, trace its origins briefly, and then make the case for fit: what does it let you see about your research problem that a different framework would miss? Pick one named alternative — Bronfenbrenner instead of Vygotsky, critical race theory instead of Bourdieu — and say specifically what it would have illuminated and what it would have missed. Committees are not asking you to defend the entire literature; they are asking whether you chose deliberately rather than by default.

How did your theoretical framework shape the way you collected and analysed data — not just how you framed it in Chapter 2?

The examiner is checking whether the framework did actual work or sat unused after the literature review. Describe two or three specific points where the framework shaped a decision: which interview questions you wrote, which codes you applied, which findings you foregrounded. If your analysis deviated from what the framework would predict, describe that too — it is often the most interesting thing in the study.

Are there critiques of your chosen theoretical framework that you need to account for?

Every major theoretical tradition in education has known critiques. Vygotsky's zone of proximal development has been challenged for underspecifying the social context; Bourdieu's concept of habitus has been criticised for structural determinism; critical pedagogy in the Freirean tradition has been challenged for romantic assumptions about consciousness-raising. Name the most significant critique of your framework and say how you addressed it or why it does not undermine your application of it.

What is the difference between a theoretical framework and a conceptual framework, and which did you use?

A theoretical framework draws on an established theory or theorist — it borrows the explanatory logic of an existing body of work. A conceptual framework is a researcher-constructed map of the concepts, relationships, and assumptions specific to a study, often drawing on several theoretical sources. Some committees use the terms interchangeably; others treat the distinction as important. Know which term your programme used, what you actually built, and be ready to explain the structure of it in plain language.

How does your framework connect to the field of education specifically, rather than to the parent discipline you borrowed it from?

Sociological theories, psychological models, and philosophical frameworks all travel into education research — but the question is whether you grounded the framework in educational contexts and educational research, or whether you applied it generically. Cite two or three education scholars who have used the same framework and say where your application of it extends or departs from theirs.

How did your professional role and experience shape what you studied, how you studied it, and what you found?

This is the positionality question. Do not give a generic answer about 'acknowledging bias.' Name your prior assumptions explicitly — what you expected to find, what you took for granted about the setting, what questions you might have overlooked because they seemed obvious to an insider. Then describe what reflexivity practices you used: a researcher journal, peer debriefing, member-checking, or returning deliberately to data that contradicted your emerging interpretation. Say what changed as a result.

You studied participants in a setting where you have professional authority or an ongoing relationship. How did that affect what they told you?

This is the power-and-access version of the positionality question. Participants who know the researcher as a colleague, supervisor, or institutional figure may self-censor, perform, or tell the researcher what they think she wants to hear. Describe what you did to create conditions for candour: whether recruitment was independent of the professional relationship, how you handled confidentiality within a small school community, and whether you saw any signs of socially desirable responding in your data.

How did you maintain an analytical distance from the setting when you know it so well?

Describe the specific analytical practices — not generic methodological virtues. Did you write memos deliberately articulating what surprised you? Did you ask a colleague outside the setting to review your codes? Did you test your interpretations against participant accounts? The examiner wants to see that your familiarity with the setting was a resource you managed deliberately, not an uncritical advantage.

How does your identity — racial, cultural, professional, or otherwise — intersect with the identities of your participants, and how did that intersection shape the research?

Identity congruence between researcher and participants creates rapport and access; divergence raises different considerations around trust and interpretation. Neither is inherently better. Describe the specific intersections that were relevant in your study, what they enabled, and what they may have foreclosed. The strongest answers name both sides: a specific way your positionality opened doors and a specific way it closed them.

What is the problem of practice your dissertation addresses — and how do you know it is a real, persistent problem rather than a theoretical one?

The Carnegie Project on the Education Doctorate defines a problem of practice as persistent, contextualised, and specific. Describe yours in those terms: name the setting, say how long the problem has been observed, and cite evidence of its persistence — data from your own setting, district records, prior research, or practitioner accounts. Candidates who define the problem at a level of abstraction that could apply to any school anywhere have not yet landed a genuine problem of practice.

An EdD contribution is to practice, not to theory. What, specifically, does your study contribute — and to whose practice?

Be concrete: name the role (classroom teachers, instructional coaches, principals, district administrators), describe what they would know or do differently after reading your work, and explain why that change is grounded in your findings rather than in your prior professional opinion. If your study also has theoretical implications, note them — but they should come second to the practice contribution, not instead of it.

How does your EdD dissertation differ from what a PhD dissertation on the same topic would look like?

The examiner is testing whether you understand the programme you are in. An EdD dissertation addresses a problem of practice in a specific organisational context; a PhD dissertation is typically expected to produce original theoretical or empirical knowledge that advances the academic field. Your study may well do both, but the primary accountability is different. Describe your study's purpose in EdD terms, and if you made design decisions that reflect that purpose — action research, improvement science, programme evaluation — explain why.

What are the policy and practice implications of your findings for the school or system you studied — and for similar settings?

Name the specific recommendations your findings support, and distinguish between what your data directly warrants and what you infer. Identify who would need to act — a principal, a district curriculum team, a state policy body — and what the organisational conditions are for implementation. If your findings are more descriptive than prescriptive, say what they tell administrators or practitioners that they did not previously have documented.

How did the people in your setting — teachers, school leaders, students — understand and engage with your research? Did any of them shape your findings?

This question tests whether you treated your research site as a data source or as a collaborative partner. In some EdD frameworks, particularly those using action research or improvement science, practitioners are co-designers rather than subjects. Describe the level of participant involvement in your study and be honest about where the boundary was. If participants reviewed findings, describe what they pushed back on and how you handled it analytically.

What would it take to scale or transfer your findings beyond the setting you studied?

Transferability in qualitative and practitioner research is not about statistical generalisation — it is about whether another practitioner in a similar setting could read your contextual description and judge whether the findings apply to them. Describe the features of your setting in enough detail that the question is answerable. Then name the conditions under which your findings are most and least likely to hold.

How did you establish the trustworthiness of your qualitative findings?

Do not just list the four criteria. Describe what each check produced. Member-checking: did participants disagree with your interpretations, and what did you do with those disagreements? Negative case analysis: what data contradicted your emerging themes, and how did encountering it change your analysis? An audit trail is evidence of trustworthiness only if someone could follow it and reconstruct your analytical decisions. If you did all four checks and nothing in your analysis changed, the examiner may ask why.

How do you respond to the argument that a qualitative study in one school, one district, or one classroom cannot tell us anything generalisable?

Generalisability is the wrong standard for most qualitative education research — transferability is the right one. Describe the contextual detail you provided to allow readers to judge whether your findings apply to their setting. Then make the case for the kind of knowledge your study produces: interpretive, conceptual, or theoretical knowledge that complements rather than competes with survey-scale studies. Committees in education are familiar with this distinction; you should be able to make the argument fluently, not defensively.

In your mixed-methods study: where and how did the qualitative and quantitative strands actually inform each other?

Integration is what committees probe hardest in mixed-methods dissertations, because it is the part most often left thin. Describe the specific analytical moments where the strands met: did the qualitative phase generate hypotheses that the quantitative strand tested? Did quantitative results identify sub-groups that the qualitative strand then examined in depth? If integration was limited, say so clearly and explain why the parallel design still served the research question better than either strand alone.

You used interviews as your primary data source. How did you guard against participants telling you what they thought you wanted to hear?

Social desirability is a particular concern in education research, where participants are often colleagues, employees, or members of the same professional community as the researcher. Describe the specific design decisions you made: how you structured questions to avoid leading, whether you used stimulus materials or observation data to prompt reflection rather than abstract opinion, whether you triangulated interview accounts against documents or observation. If you found discrepancies between what participants said and what you observed, describe how you handled them analytically.

How did you analyse your data — walk me through the actual process, not the framework you cited?

Thematic analysis, grounded theory, interpretive phenomenological analysis, and constant comparative analysis all have specific procedural logics. Describe what you actually did: how you moved from raw transcripts or field notes to codes, how you grouped codes into categories or themes, what you did when a piece of data resisted your emerging framework, and how many analytic iterations the process went through. If a colleague coded a subset of data, describe what the comparison produced.

How did you obtain access to the school or district, and what conditions — formal or informal — were placed on your research?

IRB or ethics board approval is necessary but not sufficient for school-based research. Principals, district administrators, and sometimes teacher unions can shape what is possible: restricting which classrooms you can enter, limiting what topics you can raise, or requiring review of findings before publication. Describe the access negotiation honestly, including any constraints, and say how those constraints affected your design or the scope of your findings.

How did you handle informed consent and assent for minor participants?

For research involving students under 18, parental consent is required alongside student assent in most jurisdictions. Describe the process: how consent forms were distributed, what your response rate was and whether non-responding families affected your sample, how you explained the study to students in age-appropriate terms, and what your protocol was if a student or parent withdrew consent after data collection began. If your study used only de-identified existing data, explain that classification and why it did or did not require assent.

Did your study produce any findings that raised safeguarding concerns — and if so, how did you handle them?

Research in schools can surface disclosures of abuse, mental health crises, or safeguarding concerns — particularly in studies involving student voice or wellbeing. Describe your protocol: what your mandatory reporting obligations were, how you explained those obligations to participants before data collection, and whether any disclosures occurred. If no disclosures arose, say how you had prepared for the possibility. Committees want to see that you understood your legal and professional obligations before you entered the field.

How did you protect the confidentiality of participants in a small, identifiable setting?

Confidentiality in school research is structurally harder than in anonymous survey research. A small rural school, a single grade level, or a named subject department makes participant anonymity difficult even with pseudonyms. Describe the specific anonymisation decisions you made — for the school, the district, the role, and the individual — and whether there were cases where a participant might still be identifiable to colleagues who know the setting well. If members of the school community reviewed findings, describe how you managed the tension between transparency and protection.
