CITI training for Purdue Global IRB: which modules, how current, and what a lapsed certificate costs

Purdue Global publishes an answer here that runs against the grain of what most researchers have learned elsewhere. The university accepts any one of three human-research training routes, and names the CITI Basic Course in Social, Humanistic and Behavioral Research as the first of them — then states, without softening it, that certification in a refresher course, or a responsible conduct in research course, or any course other than that basic course, will not be accepted. At a great many institutions the refresher is how currency is maintained. At this board, a refresher certificate is not the qualifying document, and a file arriving with one is not carrying what the checklist asks for.

Short answer

No. Purdue Global accepts any one of three routes: the CITI Basic Course in Social, Humanistic and Behavioral Research; PHRP computer-based training; or comparable certification from another institution. A CITI refresher or responsible-conduct course does not satisfy the requirement.

Where does the requirement come from?

Not from a departmental preference. Purdue Global's IRB explains that it is obligated to adhere to the terms of its Federal Wide Assurance with the Office for Human Research Protections, which strongly recommends that a designated board establish educational training and oversight mechanisms — appropriate to the nature and volume of its research — so that investigators, board members and staff maintain continuing knowledge of, and comply with, relevant ethical principles and federal regulations, the board's own written procedures, OHRP guidance, applicable state and local laws, and institutional policies protecting human participants. The same passage notes OHRP's recommendation that investigators complete appropriate institutional training before conducting human subjects research.

That word "before" is the whole shape of the obligation. Training is not a form filed alongside the study; it is a precondition for doing the study at all, which is why the certificate is one of the five items on Purdue Global's IRB submission checklist rather than an appendix to them. The programme catalogues repeat it: the Doctor of Nursing Practice entry states you must successfully complete IRB training and that IRB approval is required for the development of the scholarly project, and the Doctor of Education in Leadership and Innovation entry states you must complete the required IRB training and obtain Purdue Global IRB approval prior to starting data collection. Two programmes, one instruction.

Which CITI course counts?

The named course is the CITI Basic Course in Social, Humanistic and Behavioral Research — abbreviated SBR on the university's own page, corresponding to what CITI itself organises as its social-behavioural-educational track rather than its biomedical one. Purdue Global identifies the target by module count as well as by name: the basic course in SBR, at fourteen to fifteen content modules.

That the university bothers to specify a module count tells you what goes wrong. CITI is not a single course but a catalogue, and an enrolment page can present a learner with several plausible-looking options — a biomedical basic course, a refresher, a responsible-conduct-of-research course, assorted stand-alone modules. Purdue Global's guidance therefore urges stringent adherence to the directions in the instruction set, and states the consequence plainly: where somebody has not followed the instructions and has consequently completed a course other than the basic SBR course, it is that individual's own responsibility to take the correct one. The university adds that where there is any doubt, IRB staff should be contacted for direction — a much cheaper conversation than the alternative.

The three routes Purdue Global names, and what each one is
RouteWhat it isWhat to watch

The second row deserves a moment, because candidates routinely assume CITI is compulsory and spend far more effort than the requirement calls for. Purdue Global describes the PHRP option as straightforward and brief in comparison with CITI, and the requirement is expressly satisfied by any one of the three. If the goal is simply to hold an accepted certificate, that is worth knowing before you enrol.

How current must the training be?

Two halves of the university's position have to be held together here, because taken separately they mislead.

For the third route — a certificate earned at another institution — Purdue Global states it will not accept training documentation beyond a stated age. The figure is published on the IRB's own frequently-asked-questions page, and it is worth reading there rather than relying on memory, because it decides whether the certificate in your files is an asset or a piece of paper.

For the first route, the trap is subtler. Everywhere that runs a refresher cycle, "staying current" means completing the refresher when it falls due. Purdue Global's page does not treat a refresher certificate as evidence of currency; it lists refresher certification among the things that will not be accepted. So a researcher who completed a basic course years ago elsewhere, and has faithfully completed refreshers since, may hold a stack of certificates and still not hold the one this board named. The remedy is simple — complete the basic SBR course, or the PHRP training — but far cheaper discovered now than when a submission is found incomplete. None of which makes refresher training pointless; it simply is not the document this checklist asks for.

Who actually needs a certificate?

Start from what the training exists to protect and the answer follows: anyone who will interact with participants or handle identifiable information about them. Purdue Global's methodology section already asks who will administer the study, and its checklist asks for a certificate of IRB training completion — so the natural reading is that everyone named in the first answer should be covered by the second.

In practice that means thinking past yourself. If a colleague will conduct interviews when your schedule will not stretch, if an assistant will transcribe recordings, if somebody else will pull the records or run the screening calls, each is a person the file has placed in contact with participants or their data. A methodology naming three people beside one certificate is a discrepancy a reviewer can see without leaving the page.

What does the wrong certificate actually cost?

Purdue Global's instructions for completing the submission form are unambiguous about incomplete files: any items that are missing will delay the review of the submission. A certificate for a course the university has said it does not accept is, for this purpose, a missing item — the file is not held in a queue while the right one is obtained; it is simply not yet a submission the board can act on.

The cost then compounds, because the correction is not administrative. If the wrong course was taken, the right course must be taken, and the university has already placed that responsibility on the individual. Meanwhile the rest of the file waits, and the study waits with it, since data collection cannot begin before approval exists. Of all the ways a Purdue Global application can stall, this is the most avoidable — a study that is sound, careful and entirely ready, held up by a certificate naming the wrong course.

Where must the certificate agree with the rest of the file?

  • The name. The name on the certificate is the name on the application. Where a name has changed, the file makes the two obviously the same person rather than leaving a reviewer to infer it.
  • The course. What the certificate says it certifies is what the university said it accepts — the basic SBR course, the PHRP training, or comparable certification within the accepted age.
  • The people. Everyone the methodology places in contact with participants or identifiable data is covered.
  • The currency. The certificate is within the accepted range on the day the file is read, not the day it was first drafted.
  • The route in. The submission goes in from a Purdue Global email address, and travels first to a thesis adviser, consultant or instructor, or supervisor for approval before reviewers see it — so the certificate is being read by that person too.

That is the discipline every other document is held to: one dimension, several documents, no disagreement. The application checklist shows the certificate's place among the five items, and the step-by-step route shows where in the sequence it must already exist.

How we handle training in a file

Training is the first thing we check when a file arrives, because it is the cheapest finding to make and the most expensive to discover late. We read the certificate against what the university currently names as accepted, check the course rather than the logo, check the name and the currency, and check the methodology for every other person who will touch participants or identifiable data. If it does not match, we say so on the first pass and tell you which route is quickest from where you stand — often the shorter of the three rather than the one you assumed was compulsory. Our how-it-works sheet and the questions page cover the rest. The study stays yours; the determination belongs to the board.

What to do next

Open the certificate you plan to submit and read the course title on it, not the provider's name. If it says refresher, or responsible conduct of research, or names a biomedical track, it is not the document Purdue Global's page describes — a fixable problem today and an expensive one later. Ask for the free application review and send the certificate with whatever else exists; we will tell you whether it will be accepted, who else in your study needs one, and what the fastest accepted route is if it will not.
