Can Researchers Decide for Themselves That Their Study Does Not Need Ethics Approval?

Can You Simply Decide That Your Research Does Not Need Ethics Approval?

You know your project better than anyone. You have read the ethics guidelines, the study seems harmless, and perhaps you are confident that it is exempt or does not involve the kind of research your ethics committee reviews. Why submit anything at all?

This is where a reasonable research judgment can become a governance problem. Researchers should think carefully about whether ethics review applies to their work, but being able to assess the question does not necessarily mean you have authority to make the institution's formal determination yourself.

Self-Assessment Is Useful, but It May Not Be the Final Decision

Where Researcher Judgment Ends and Formal Ethics Authority Begins

You Should Make a Preliminary Assessment

Researchers are not expected to submit blindly. You should understand enough about the applicable ethics framework to recognize whether your work involves human participants, identifiable private information, human biological materials, interventions, sensitive information, vulnerable populations, or other features relevant to review.

You should also be able to identify whether a project might fall outside the applicable definition of human-participant research or might satisfy an exemption category.

That preliminary assessment is part of responsible research planning. The mistake is treating it as automatically equivalent to whatever formal determination your institution requires.

“I Don't Need Approval” Can Hide Several Different Conclusions

When researchers say that their study does not need ethics approval, they may actually mean quite different things.

These are classification questions. They depend on definitions and criteria rather than the researcher's preferred label.

In the Philippine Framework, Researchers Do Not Make the REC Exemption Decision

The 2022 Philippine National Ethical Guidelines provide a clear procedural answer for exemption. After submission, the REC Chair or representative determines whether the proposal is exempt or whether full or expedited review is required. The guidelines state explicitly that “Exempt from Review” is a decision made by the REC.

A Philippine researcher working under this framework can therefore explain why a protocol appears eligible for exemption, but should not substitute that assessment for the REC determination required by the applicable process.

The U.S. Common Rule Is More Procedurally Flexible, but OHRP Still Recommends Independent Determination

Under the U.S. Common Rule, federal regulations generally do not specify who at an institution must determine that research qualifies for exemption. This gives institutions flexibility to establish their own procedures.

OHRP nevertheless recommends that investigators not be given authority to independently determine that their own human-subject research is exempt because of the potential for conflict of interest. Most research institutions instead rely on an IRB or Human Research Protection Program office or other designated personnel with appropriate regulatory knowledge.

This distinction matters: “the federal regulation does not require the IRB itself to make every determination” does not mean “every researcher can simply decide for themselves.” Institutional policy fills much of that procedural space.

Why Is Independent Determination Valuable?

Researchers have several potential blind spots. The most obvious is conflict of interest: starting sooner is usually advantageous to the investigator. But technical classification is another issue. Terms such as research, human subject, identifiable private information, minimal risk, and exempt can have specific regulatory meanings that differ from their everyday meanings.

OHRP notes that determinations about whether a study is nonexempt human-subject research can be complicated and often require detailed knowledge of regulatory definitions. It explains that institutions commonly rely on experienced HRPP or IRB personnel for precisely this reason.

Independent determination can also promote consistency. Two investigators with essentially identical protocols should not reach opposite regulatory conclusions merely because one is cautious and the other is adventurous with definitions.

A Researcher Can Be Right and Still Need Documentation

Suppose you correctly conclude that your study does not require full ethics review. That may still leave a practical question: can you demonstrate why?

A journal, funder, collaborator, research site, auditor, or institutional office may later ask about the ethics status of the study. An institutional determination stating that the project was exempt or did not require IRB review can provide evidence that the issue was considered before research began.

OHRP's training materials specifically note that institutional determinations can help when journals request evidence of independent consideration of human-research protections.

Ethics Approval, Exemption, and “Not Human-Participant Research” Are Not Interchangeable

Researchers sometimes use “no ethics approval required” as a catch-all phrase. It is better to preserve the actual basis for the determination.

A third possibility is nonexempt human-participant research that requires ethics review and approval. These classifications can have different procedural and documentation consequences.

“Low Risk” Is Not Authority to Skip the Process

Researchers commonly reason that no ethics review is necessary because nothing serious could happen to participants. Risk certainly matters, but it does not answer every classification question.

A low-risk protocol may qualify for exemption, may require expedited review, or may fall outside a particular framework depending on its characteristics and governing rules. The relationship between exempt, expedited, and full ethics review is more structured than a simple low-to-high risk scale.

“Anonymous” Is Also Not a Self-Executing Exemption

Anonymity can substantially affect privacy and confidentiality risk, but it does not automatically settle the study's ethics status. An anonymous questionnaire can still involve interaction with human participants, sensitive questions, coercive recruitment, vulnerable participants, or other ethical considerations.

The fact that a survey is anonymous is therefore evidence relevant to the assessment, not universal permission to bypass it.

Existing and Public Data Create Similar Traps

Secondary-data research often feels detached from human-participant research because the investigator never recruits or speaks to anyone. But whether ethics requirements apply can depend on identifiability, how data are obtained, whether the information is private, and the governing framework.

OHRP specifically recommends that institutions designate the person or entity authorized to determine whether secondary research involving coded private information or biospecimens constitutes exempt or nonexempt human-subject research. It recommends against allowing investigators independently to make that determination.

Researchers should therefore assess existing-data research and research using publicly available data according to the relevant rules rather than assuming that lack of direct participant contact resolves the question.

Student Status Does Not Create a General Exception

A student researcher may understandably look to a thesis adviser or professor for guidance. Academic supervision, however, is not necessarily equivalent to institutional authority to determine ethics status.

The student's responsibilities and review requirements depend on the nature of the project and the institution's rules. The question of whether student research requires ethics approval should therefore be answered from the protocol and governing framework, not simply from the researcher's status.

Publication Plans Do Not Fix a Missing Prior Determination

Another risky approach is to conduct a project first and deal with ethics only if the results become worth publishing. That reverses the logic of prospective ethics oversight.

If prior review or a determination was required, deciding to publish later does not recreate the independent assessment that should have occurred before the relevant research activities began. Researchers should settle the ethics status during study planning rather than treating it as a manuscript-submission problem.

What if Your Institution Really Does Allow Researcher Self-Screening?

Some systems may use institutional self-screening tools or procedures that permit investigators to reach or operationalize a determination under defined conditions. OHRP acknowledges that an institution could design a checklist or web-based process allowing investigators to complete specified questions and, when the required answers establish exemption, begin research after filing the information without waiting for another person's prior review.

The important point is that this would be an institutionally authorized process, not a researcher privately deciding that the rules do not apply. The institution remains responsible for designing a process capable of producing accurate determinations.

When an Obvious “No Review Needed” Study Is Not So Obvious

The researcher may ultimately have been correct that ordinary ethics review was unnecessary. The error would have been treating that prediction as sufficient authority to bypass the institution's required determination process.

Common Reasons Researchers Incorrectly Skip Ethics Review

Screen Your Study, Then Follow the Authorized Process

Your role is not passive. Learn enough about research ethics to recognize potential review requirements, prepare an accurate protocol, and identify the classification that appears to fit. Then determine what your institution requires before acting on that assessment.

The objective is not to submit every conceivable project for full committee review. It is to make sure that the decision to bypass ordinary review is itself made through the correct process.
