Exempt Categories

Research that qualifies for “Exempt” review involves minimal risk to subjects, among other requirements. This kind of research is exempt from most of the Federal Policy for the Protection of Human Subjects requirements, but is still considered research that requires a determination from the IRB.

Definitions of each category from the regulations are provided below. Qualification for each exempt category may depend on other study factors. When you’re filling out your IRB submission form, questions will be asked to allow reviewers to determine whether your study activities fall within any of these exemption categories.

Category 1 (educational settings)

Research, conducted in established or commonly accepted educational settings, that specifically involves normal educational practices that are not likely to adversely impact students’ opportunity to learn required educational content or the assessment of educators who provide instruction. This includes most research on regular and special education instructional strategies, and research on the effectiveness of or the comparison among instructional techniques, curricula, or classroom management methods.

Examples of research exempt under Category 1
  • A study on the effectiveness of a science curriculum in use. Investigators will observe classroom instruction and collect quizzes and class evaluations that are part of the curriculum and classroom practices.
  • A study comparing two curricula in use. Investigators will observe classrooms and interview instructors about their experiences using the instructional materials, but not about specific students.
  • A study comparing driver’s education curricula in use. The investigator will observe classes and compare driving test scores at the end of the courses.
Category 2 (surveys, interviews, and public observations)

Research that only includes interactions involving educational tests (cognitive, diagnostic, aptitude, achievement), survey procedures, interview procedures, or observation of public behavior (including visual or auditory recording) if at least one of the following criteria is met:

  1. The information obtained is recorded by the investigator in such a manner that the identity of the human subjects cannot readily be ascertained, directly or through identifiers linked to the subjects;
  2. Any disclosure of the human subjects’ responses outside the research would not reasonably place the subjects at risk of criminal or civil liability or be damaging to the subjects’ financial standing, employability, educational advancement, or reputation; or
  3. The information obtained is recorded by the investigator in such a manner that the identity of the human subjects can readily be ascertained, directly or through identifiers linked to the subjects, and the IRB conducts a limited IRB review to make the determination required by §46.111(a)(7).

Category 2 does not apply to research with children (45 CFR Part 46 Subpart D) except for research involving educational tests (cognitive, diagnostic, aptitude, achievement) or observations of public behavior when the investigator(s) do not participate in the activities being observed.

Examples of research exempt under Category 2
  • A study involving an anonymous survey regarding workplace satisfaction at area businesses.
  • An observational study of pedestrians crossing a street; the researcher takes notes of what occurs, recording sex, race, and type of clothing of pedestrians, but does not interact with subjects.
  • A study involving interviews with college seniors (age 18 and older) about their plans after graduation. The answers to questions asked would present no risks to subjects if disclosed outside the research.
  • A study involving focus groups with expectant mothers regarding their perceptions of parenting education.
Category 3 (minimal risk procedures)

Research involving benign behavioral interventions in conjunction with the collection of information from an adult subject through verbal or written responses (including data entry) or audiovisual recording if the subject prospectively agrees to the intervention and information collection and at least one of the following criteria is met:

  1. The information obtained is recorded by the investigator in such a manner that the identity of the human subjects cannot readily be ascertained, directly or through identifiers linked to the subjects;
  2. Any disclosure of the human subjects’ responses outside the research would not reasonably place the subjects at risk of criminal or civil liability or be damaging to the subjects’ financial standing, employability, educational advancement, or reputation; or
  3. The information obtained is recorded by the investigator in such a manner that the identity of the human subjects can readily be ascertained, directly or through identifiers linked to the subjects, and the IRB conducts a limited IRB review to make the determination required by §46.111(a)(7).

If the research involves deceiving the subjects regarding the nature or purposes of the research, this exemption is not applicable unless the subject authorizes the deception through a prospective agreement to participate in research in circumstances in which the subject is informed that he or she will be unaware of or misled regarding the nature or purposes of the research.

Examples of research exempt under Category 3
  • A study that involves asking subjects to play an online game.
  • A study that involves asking subjects to solve puzzles under various noise conditions.
  • A study that involves asking subjects to decide how to allocate a nominal amount of received cash between themselves and someone else.
UCSC Category 3x (rarely used at UC Santa Cruz)

Minimal risk exempt research activities that will not induce distress beyond that of daily life may include non-physically invasive interventions or performance of tasks.

Exclusions that apply to UCSC Category 3x:

  • Research funded by any Common Rule department or agency. To find funding agencies to which the regulations apply see HHS Agencies & Offices or check with your sponsor to see if they follow the Common Rule.
  • Prisoners as subjects.
  • Children/minors as subjects.
  • Federal personnel or the Department of Veterans Affairs.
  • Procedures, devices, or drugs subject to FDA oversight.
  • Biomedical procedures.
  • Clinical interventions.
  • Sponsor or other contractual restrictions.
  • An NIH-issued Certificate of Confidentiality to protect identifiable research data.
  • Deception or incomplete disclosure to subjects.
  • Identifiable, private existing data.
  • The information obtained is recorded in such a manner that subjects can be identified, directly or through identifiers linked to the subjects, and any disclosure of the subject’s responses outside of the research could reasonably place the subject at risk of criminal or civil liability, be damaging to the subject’s financial standing, employability, insurability, or reputation, or be stigmatizing in any other way.
Examples of research exempt under UCSC Category 3x
  • A study in which subjects will perform any of the following:
    • Reading/writing/drawing tasks.
    • Physical activities such as walking, sitting, or manipulating an object. 
    • Computer tasks and/or Internet searches.
    • Talking and/or listening to words, then making selections, or “think-aloud” exercises.
    • Viewing media.
    • Role-playing.
    • Completing a specific physical or mental action (“imagining”).
    • Playing a game.
  • A study that involves the passive monitoring of space (environment) with sensors.
  • A study that involves obtaining subjects’ height and/or weight measurements.
Category 4 (secondary use of data)

Secondary research for which consent is not required: secondary research uses of identifiable private information or identifiable biospecimens, if at least one of the following criteria is met:

  1. The identifiable private information or identifiable biospecimens are publicly available;
  2. Information, which may include information about biospecimens, is recorded by the investigator in such a manner that the identity of the human subjects cannot readily be ascertained directly or through identifiers linked to the subjects, the investigator does not contact the subjects, and the investigator will not re-identify subjects;
  3. [this criteria is not utilized at UC Santa Cruz]The research involves only information collection and analysis involving the investigator’s use of identifiable health information when that use is regulated under 45 CFR parts 160 and 164, subparts A and E, for the purposes of “health care operations” or “research” as those terms are defined at 45 CFR 164.501 or for “public health activities and purposes” as described under 45 CFR 164.512(b); or
  4. The research is conducted by, or on behalf of, a federal department or agency using government-generated or government-collected information obtained for non-research activities,
    • if the research generates identifiable private information that is or will be maintained on information technology that is subject to and in compliance with section 208(b) of the E-Government Act of 2002, 44 U.S.C. 3501 note, 
    • if all of the identifiable private information collected, used, or generated as part of the activity will be maintained in systems of records subject to the Privacy Act of 1974, 5 U.S.C. 552a, and, 
    • if applicable, the information used in the research was collected subject to the Paperwork Reduction Act of 1995, 44 U.S.C. 3501 et seq.
Examples of research exempt under Category 4
  • A study in which a student will be given access to data from a health survey research project. The data consists of coded survey responses, and the principal investigator of the health survey research project in which the data was collected will retain a key that would link the data to identifiers. The student will extract the information they need for their project without including any identifying information and without retaining the code. The use of the data does constitute research with human subjects because the initial data set is identifiable (although through a coding system).
  • A study of treatment outcomes for a certain drug that involves the review of patient charts at a non-UCSC medical facility. The researcher records patient age, sex, diagnosis, and treatment outcome in such a way that the information cannot be linked back to the patient.
Category 5 (not applicable at UC Santa Cruz)

Research and demonstration projects that are conducted or supported by a federal department or agency, or otherwise subject to the approval of department or agency heads (or the approval of the heads of bureaus or other subordinate agencies that have been delegated authority to conduct the research and demonstration projects), and that are designed to study, evaluate, improve, or otherwise examine public benefit or service programs, including procedures for obtaining benefits or services under those programs, possible changes in or alternatives to those programs or procedures, or possible changes in methods or levels of payment for benefits or services under those programs. Exempt projects also include waivers of otherwise mandatory requirements using authorities such as sections 1115 and 1115A of the Social Security Act, as amended.

Each federal department or agency conducting or supporting the research and demonstration projects must establish (on a publicly accessible federal website or in such other manner as the department or agency head may determine) a list of the research and demonstration projects that the federal department or agency conducts or supports under this provision. The research or demonstration project must be published on this list prior to commencing the research involving human subjects.

Examples of research exempt under Category 5
  • A study that includes internal studies by federal employees.
Category 6 (taste and food)

Taste and food quality evaluation and consumer acceptance studies:

  1. If wholesome foods without additives are consumed, or
  2. If a food is consumed that contains a food ingredient at or below the level and for a use found to be safe, or agricultural chemical or environmental contaminant at or below the level found to be safe, by the Food and Drug Administration or approved by the Environmental Protection Agency or the Food Safety and Inspection Service of the U.S. Department of Agriculture.

Studies involving the consumption of alcohol, vitamins, and other supplements do not qualify for exempt status.

Examples of research exempt under Category 6
  • A study involving a taste-test on different varieties of an additive-free fruit to determine consumer preference.
  • A study that involves taste-testing of various beef products from cattle that have been given feed.
