Does a Purdue Global doctoral project need IRB approval? QI, determinations and the honest claim
Assume yes until the board says otherwise in writing. Purdue Global's own program catalogs state that ethics training must be completed and Purdue Global IRB approval obtained before data collection for a doctoral project begins, and the board publishes a dedicated pathway for the case where a project turns out not to be research at all. That pathway does not end in silence. It ends in a determination letter — a document you can hold up — and the way to get one is to describe the project you actually designed rather than the one whose category is more convenient.
Short answer
Purdue Global requires IRB approval before doctoral project data collection. If the project is genuinely local quality improvement rather than research, the Human Research Determination pathway produces a letter saying so. Either way the board decides, not the project's label.
What do Purdue Global's own program materials require?
They put it as a progression condition, not as advice. Across the applied doctoral sequences, the university's catalog states that ethics training must be successfully completed and Purdue Global IRB approval obtained before data collection for the project starts. The nursing catalog carries the requirement against the practice-focused final project; the business catalog states it for the doctoral project sequence and adds that permission must be secured to conduct the applied project at the chosen site; the health science catalog carries the same condition against its project sequence.
The education sequence is the most explicit of all about where the work sits: one of its applied research courses is named for IRB preparation directly, and the program describes the review as one of the stages the coursework guides you through. So the question is not whether the board is in your path. It is which pathway of the board's three you belong on, and what you have to demonstrate to be there.
| Sequence | Shape of the culminating work | What the catalog conditions on the board |
|---|---|---|
| Nursing | A practice-focused final project across a proposal, an analysis course, implementation and dissemination | Ethics training completed and IRB approval obtained for the scholarly project |
| Business | A four-part doctoral project from problem statement through design, analysis and dissemination | IRB training and Purdue Global IRB approval before data collection, plus written site permission |
| Education | An applied research project and paper developed across several terms, including a course dedicated to IRB preparation | IRB training and Purdue Global IRB approval before data collection, plus site permission |
| Health science | A four-part doctoral project from proposal through data collection and dissemination | Ethics training completed and IRB approval required for project development |
What separates research from quality improvement?
One clause. Federal regulation defines research as a systematic investigation, including development, testing and evaluation, designed to develop or contribute to generalizable knowledge. Quality improvement, in the ordinary case, is a systematic investigation too — that is not the distinguishing feature. What distinguishes it is design intent: whether the work is built to change one local process in one place, or built to produce knowledge meant to travel.
Purdue Global's own pathway description tracks that clause closely. Its Human Research Determination route is offered for non-research activities such as quality assurance, quality improvement and program evaluation intended for local improvement, and it tells you to select the route when the primary objective is improving a specific local service or workflow rather than addressing a research question or testing a hypothesis — projects intended to benefit a single site or practice and not designed to contribute to generalizable knowledge.
Read that sentence as a specification and it becomes measurable. Single site. Local service or workflow. No hypothesis under test. No design intent to generalize. Four dimensions. Your protocol either reads that way in every document or it does not.
Does intending to publish turn quality improvement into research?
No, and this is the single most common misreading in doctoral work. The Office for Human Research Protections addresses it directly in its quality improvement guidance: the intent to publish is an insufficient criterion for determining whether a quality improvement activity involves research. Dissemination is what you do with a finding, not what the finding is.
That matters at Purdue Global specifically, because dissemination is a required, named stage of the applied doctoral sequences. Presenting your work is built into the program. If publication converted projects into research by itself, every quality improvement project in the university would be research by construction, and the determination pathway would have no purpose.
The inverse error is just as costly, though. OHRP is equally clear that some improvement efforts are research — its example is a project that introduces an untested clinical intervention partly to improve care and partly to gather outcome information for the purpose of establishing scientific evidence about how well the intervention works. Untested intervention, plus evidence-building intent, equals human subjects research whatever the project is called on the cover sheet.
Which features of a design contradict a quality improvement claim?
Run this list against your own protocol before the reviewer does. Each item is a place where the design speaks louder than the label.
- A comparison built to isolate an effect. Randomization, a control arm, a matched group or staggered rollout designed so the difference between conditions is interpretable.
- An untested intervention. Applying something not already established as practice at your site, rather than implementing a practice already known to work.
- An instrument you are validating. Testing whether the tool measures what it claims, as opposed to using an accepted tool to watch a local process.
- Recruitment. Approaching people, enrolling them, consenting them — as distinct from observing a workflow that would run identically without you.
- Data gathered because of the project. New collection created for the inquiry, rather than material already produced by care, teaching or administration.
- Sampling built for inference. A sample size justified by power rather than by who happens to be on the unit.
- Multiple sites. The moment findings are meant to hold across settings, the word local is doing no work.
- A hypothesis in the aim statement. Framing the question as something to be tested rather than something to be improved.
None of these makes a project worse. Several make it stronger. They simply move it onto a different pathway, and moving it early is inexpensive while moving it after a return is not.
What does the determination pathway actually produce?
A letter. Purdue Global states that the purpose of the Human Research Determination pathway is to obtain a determination letter from its IRB confirming non-research status, and the route has its own instruments: a determination worksheet to self-assess against, and a protocol form specific to the pathway. The board also maintains a standard operating procedure for determining human subject research, which is to say that this decision has a documented process behind it rather than resting on a reviewer's mood.
Notice what the letter is worth downstream. A project that proceeded on a private assumption of non-research status has nothing to show a journal editor, a site's compliance office, an employer or a future board. A project that holds a determination letter has the institution's own reading of it in writing, dated, from the body with authority to make it. The letter is an asset; the assumption is an exposure.
Purdue Global's published guidance also gives the honest default for the ambiguous case: when in doubt, submit. A determination request that comes back saying no review is required has cost you an application. A study conducted without one that turns out to have needed review cannot be repaired afterwards, because approval does not reach backwards — the point we make about the approval datum in the step-by-step sequence.
What if the determination goes the other way?
Then the project moves onto the exempt or expedited pathway, and the file changes with it. That is not a setback and it is not a judgment; it is a different form set, a participant-facing document that the determination pathway did not require, and a different set of criteria to satisfy. Exempt, expedited or full board at Purdue Global walks the criteria for each.
What makes this expensive is discovering it late. A protocol written to sound like quality improvement, with a consent-free design and a site letter that speaks about process improvement, has to be redrawn from the aim statement outward when the category changes. A protocol written honestly from the start moves pathways by changing its form set, not its argument.
Why is the honest claim also the cheaper one?
Because the reviewer reads the design, not the tick box. Every document in the packet is a second measurement of the same study, and a category claim that disagrees with the methodology section is the same defect as a sample size that disagrees with the consent form: one dimension, two readings. The board does not have to decide which reading is true to return the file. It only has to notice both.
The version of this that costs the most is the one where the claim is nearly right. A single-site improvement project with one comparison group tucked into the analysis plan. A workflow evaluation with one validated instrument in the appendix. Those files read as quality improvement until page nine. Straightening them before submission takes one honest reading of the design against the claim — the reading the first measure exists to perform.
What to do next
Send the aim statement, the method section and whatever else exists through the intake sheet and take the first measure, which is free. The design gets read as you drew it, and what comes back says in writing which pathway it belongs on, which sentences argue against the category you were planning to claim, and what remains to be drawn — or that nothing does. If carrying it yourself has stopped being appealing, the whole sequence can move across: category, documents, filing, and every answer the reviewers ask for until a letter exists, whether that letter is an approval or a determination. Your project, your data, your conclusions stay where they are. The ruling belongs to the board, and nothing written here anticipates it. See how it works, or the questions page for shorter answers.
