Changing an approved GCU study: what needs the board's yes before it happens
Approval is not a description of your study. It is a permission with a shape, and the shape is the file the board read. The moment the work stops matching that file — a second site, a reworded question, a colleague added to the team, a recruitment route that is not working — the change needs the board before it is used, not after. There is exactly one exception, and it is narrower than most people assume.
The short answer
Changes to an approved study are reviewed and approved before they are put into practice. The one exception in the federal rule is action taken to remove an immediate hazard facing a participant. GCU handles the rest through a modification form reserved for already-approved files.
Why does a change need approval before it happens?
Because that is the rule the board itself operates under. 45 CFR 46.108(a)(3)(iii) requires written procedures that ensure any change proposed to a study is reported promptly, and that the work continues on the approved terms until such a change has been reviewed and approved — except where action is required at once to eliminate apparent immediate hazards to a participant. That clause is the whole of the exception. It covers stopping something that is hurting someone; it does not cover convenience, a closing recruitment window, or a site that has become difficult.
GCU's convened-board procedure says the same in institutional language: changes to the conditions or protocols of research approved by full review must be reviewed for approval. The consequence in a doctoral file is that data collected under an unapproved change sits outside the approval that authorised the study. Not a paperwork problem — a data problem, discovered late.
Is this a modification, or is it a revision?
These are different objects in GCU's portal, and using the wrong one costs a cycle. GCU states it plainly: the modification form should only be used by those who have approved applications. If your application has not been approved and a reviewer has asked for changes, what you owe is a revision inside the original submission packet, not a modification — the mechanics of which are set out in answering the board's revisions.
The distinction is easiest as a question about what already exists: a revision repairs a file that has not yet earned its letter; a modification changes a study that already has one.
Which changes need to go to the board?
Assume that anything the board was told in the approved file, and anything a participant was promised, needs the board before it changes. GCU's modification form makes the categories explicit — its type-of-modification section gates every other section, so what you tick determines what you can edit.
| The change | Approval before it happens? | What has to move with it |
|---|---|---|
| A new or replacement site | Yes | A site authorization letter from the new site, on its letterhead, signed by someone with authority, describing exactly the activities you will carry out there — matched word for word to the procedures in the application |
| A new data collection procedure | Yes | Revised recruitment script and consent where the new procedure changes what participants are asked to do or told; both uploaded with the form |
| Adding or removing team members | Yes | Current human-subjects training for anyone added, with names matching the protocol exactly |
| Changing your chair | Yes | GCU asks you to email the IRB office with the new chair's name and wait for a reply before submitting the modification form |
| A change in enrolment | Yes | Any material supporting the new numbers, plus every document that states a sample size |
| Consent or assent wording | Yes | A revised version created through the form's revision route, with the change explained in the text box provided |
| Recruitment materials | Yes | The revised material, plus a check that it promises nothing the consent does not |
| An instrument — swapped, reworded, or a new one | Yes | The instrument as it will be used, with permission or licence attached, and the alignment back to what your committee approved |
| Study title | Yes | Consistency with the title used on site letters and consent documents already in circulation |
| Removing an immediate hazard to a participant | Act first, report promptly | The federal exception; the board is told immediately afterwards, and the change is then reviewed |
Two changes people assume are internal are not. Adding a colleague who will handle identifiable data changes who can see participants' information — a promise the consent made. And extending recruitment to a population the sample section does not name changes who is being asked, which is exactly what equitable selection is about.
How does GCU's modification form work?
The form lives inside the study record in GCU's IRB portal, reached through the study assistant and the list of your studies, and created fresh the first time you need one. It is built in numbered sections, and the important structural fact is that the type-of-modification section acts as a switchboard: sections for new data collection procedures, title, personnel, sites, enrolment, consent, recruitment, instruments and other changes only open if you have ticked them. A change you forget to tick is a section you cannot fill in.
Documents attach at the end of the form, and consent revisions have their own route inside the consent section: select the existing document, create a revision — the version updates itself — check it out, complete the checkout, edit, then check it back in and save. The same discipline that governs a revision response governs a modification, and for the same reason: one versioned record, not a folder of loose files.
Where the modification is being read by the convened board, GCU's procedure asks for more than the form. It expects the amendment to arrive with a detailed description of the proposed changes and a rationale for them, a revised protocol — preferably in tracked-changes form — and revised consent or authorization documents in both tracked-changes and clean form. It also asks that significant amendments be incorporated into the current protocol so that only one complete protocol exists, with revision dates noted. A study that accumulates amendments as a stack of addenda gets harder to approve with every round.
Can a modification change the level of review?
Yes, and this is the part that catches otherwise careful files. Minor changes to previously approved research may be handled under the expedited procedure — 45 CFR 46.110(b)(1)(ii) says so directly. But a change that raises the risk, or that brings in a population the regulations protect, is not minor. GCU's own review decision matrix states the governing principle in one line: the level of review for the entire research proposal is determined by the most stringent requirement that applies to it.
So a study approved under an expedited procedure that adds, say, participants below the age of majority does not add a small expedited amendment. It reopens the question of what level of review the whole study now requires. The honest planning move is to ask that question before the change is designed, not after the form is half-completed.
What about the exhibits that expire on their own?
A study can drift out of alignment without anyone changing anything. GCU's doctoral package checklist asks whether the site authorization or the permission to use an instrument has gone out of date, and expects a clear date and time stamp to be visible on it. The site authorization letter template carries the same warning from the other side, telling the researcher that the letter's date must cover the whole period of data collection and that a fresh letter should be obtained as the date approaches. Neither of these is a change you make. Both are changes that happen to you, and both are things the board notices.
Where the change involves records rather than people — a new dataset, a different extract, another archive — GCU routes limited, proprietary or private datasets through a data use agreement, which is expected to align with the IRB application and, where relevant, the site authorization. A new source of data is a modification with an agreement attached, not a quiet substitution.
What should never be done instead of a modification?
- Collecting first and amending later. The regulation is written the other way round, and the board reads dates.
- Treating a chair's agreement as approval. Your chair's yes moves the file; it does not authorise the change.
- Opening a second application for the changed study. The record is one study with versions.
- Changing the method without the committee. A design change is a change to the study, and it goes back through your chair and committee before it reaches the board as an amendment.
- Letting a modification quietly fix something the board never saw. If a mismatch has been discovered, say what it is. A modification that repairs a problem while pretending to be routine is a much worse document than one that says plainly what went wrong.
What to do next
If something about your approved study has changed, or is about to, send us the approval letter and a sentence describing the change. The free application review returns a written finding: whether the board is needed before it happens, whether it counts as a minor change or reopens the level of review, which exhibits have to be rebuilt, and what needs your chair first. Amendments and continuing review are exactly the kind of work this desk carries end to end after approval — how it works sets out what moves and what stays with you, and what happens after approval covers the rest of the study's life. Your research stays entirely your own; the ruling stays entirely with the people appointed to make it.
