A copy of the New Principal Investigator Letter that provides guidance and contact information is provided below.
Dear Principal Investigator (PI):
You are receiving this message as you have submitted a protocol for using animals in research or teaching. Below is a list of items in regard to the Institutional Animal Care and Use Committee (IACUC) and your protocol.
- The entire review process can be up to 4 to 6 weeks. Reviews include a veterinary, hazardous agent, occupational health and IACUC review.
- Please reply promptly if you receive a message from the IACUC office or the IACUC coordinator on any clarifications or additions to the protocol.
- No work on this protocol can begin until you receive a written correspondence (email or letter) stating that the protocol was APPROVED from the IACUC office.
- As a PI, it is your responsibility to insure all personnel listed on your protocol have read the protocol, have completed their training and are enrolled in/waived the UT Occupational Health Program.
- Only people listed on the protocol can work on the project. A personnel amendment must be submitted to the IACUC office before any new personnel can begin work. Amendment forms are available on the IACUC website.
- If any procedures need to be changed, an amendment must also be submitted and approved prior to initiating the change.
- If any animals become sick/injured, require veterinary care, display unexpected/unrelated clinical signs, unexpected/unrelated mortality, or a high number of mortality, the IACUC office or the UT Attending Veterinarian must be contacted.
- If there is an unexpected occurrence or questions arise about any parts of the protocol, please contact the IACUC office.
- Protocols are approved for a period of 3 years; however, every year you must submit a renewal form to inform the IACUC of the number of animals used and if any personnel need to be removed from the protocol.
- Annual IACUC refresher training is typically required. As the PI, it is your responsibility to ensure all on your protocol are aware of the training and complete it once notified.
- Once your protocol is approved, you will be granted access to the IACUC Sharepoint site which allows you to view your protocol, any amendments and other important information.
- Any time during the life of your protocol, you may be asked to undergo a post-approval monitoring (PAM) session to ensure the work on the animals is as written in the protocol.

Any individuals providing animal husbandry or care (with the exception of facility staff) should be listed on the personnel table of the IACUC Protocol Form. All individuals listed will be required to complete an enrollment or waiver form for the Occupational Health Program and the AALAS Learning Library Module “Working with the IACUC” prior to having access to animal facilities. Additional information can be found by clicking on the “Training” link on the left-hand side of the screen.
All issues or questions related to animal husbandry (caging, space availability, per diems for research animals, etc.) should be directed to facility managers. Contact the OLAC Office at (865) 974-5634 to get in touch with the appropriate facility manager.
The up-to-date Animal Care and Use forms are located at on the Forms page.
Amendment forms for either personnel or procedural changes can be found in the red tab mark “Forms“. Institutions with large numbers of approved protocols often use an amendment form to document proposed changes in protocols. Depending on the specific changes requested, questions to be answered for each protocol amendment should include:
- What is the purpose or rational for the protocol amendment?
- Will different people use the animals? If personnel have changed, their qualifications (e.g., education, training and experience) must be documented.
- Will the species, sex of strain of animal change?
- Will there be specialized housing requirements (e.g., housing that is not standard for the species, or housing which does not meet the animal’s physiological or behavioral requirements?
- Will more animals be needed? If so, justification for the increased number must be provided.
- Will additional minor surgical procedures or sampling of body fluids or tissues occur?
- Are animals expected to experience more clinical illness, pain, or distress as a result of the procedures proposed in this amendment? Are there alternatives to the use of animals in painful procedures? How will any pain or distress from this new procedure be minimized?
- Will there be new procedures involving animals? Such changes must be described with the same level of detail as is required for a new protocol.
- Will there be a change in the methods of euthanasia, analgesia, or anesthesia?
- Will prolonged restraint of conscious animals be required?
- Will new hazardous agents be used?
- Will the surgical plans change (minor to major, multiple survival surgery, additional procedures)?

File 000178 and UTK has received full accreditation by AAALAC
The short answer is: Expect it to typically take 3-8 weeks.
The complete answer is: The review process begins upon receipt of your protocol. An administrative review occurs shortly after protocol receipt to insure that the form has been thoroughly and properly completed. The committee coordinator may contact you with questions or comments which require your attention and responses. Following the administrative review, the protocol is forwarded to the OLAC veterinarians for a review of the veterinary aspects of your planned study. During the veterinary review, the protocol is assigned a pain and distress category based on the described animal procedures. This category is the primary factor determining the method of review by the IACUC and is based on the USDA pain categories.
The Biosafety Office will assess any hazardous risks included in the protocol and the Occupational Health Program (OHP) to review the personnel section of the protocol. The Biosafety Officer and the OHP director may contact the PI with questions. Following released from veterinary review, the protocol is sent to the IACUC chair for reviewer assignment, which is based on protocol content and the pain/distress category.
The UTK IACUC uses designated member review process during which any member of the committee may call any protocol to full committee review. If a protocol is called to full review, the protocol will be discussed at the next scheduled meeting. If the protocol remains in the designated member review process, the committee has seven days during which they may review the protocol and send the selected reviewer comments or questions. After the seven days, the reviewer compiles the questions and comments and sends them to the coordinator, who will contact the PI. The PI will be given specific instructions to revise the protocol to address the questions and comments identified during the review process. Upon receipt of the revised protocol, the coordinator will distribute the revised protocol to the entire committee for a final review period.
Our PHS Assurance includes a 72-hour continued review period. After all questions have been adequately addressed and the protocol is in final version and the protocol completed the 72-hour continued review, the approval letter will be prepared for signature and the protocol will be distributed to key individuals (the PI, animal facility managers, REC personnel, OLAC).
So, how long to receive protocol approval depends on the review process and the turn-around time for questions to be sent and responses to be received from the PI and the committee members.
Amendments need to be submitted before any change is made to a protocol. The chair has authority to approve on behalf of the committee personnel additions (but not a change of the principal investigator) and an increase of animal number of 1 or up to 10% of the original number approved, and minor procedural changes. Amendments are reviewed in a similar method to that of protocols: amendments are sent to the OLAC office for veterinary review and if there is a safety component, the amendment is also sent to the Biosafety Officer. OHP is contacted for personnel additions.
Upon release from veterinary review the amendment is either assigned to the designated member review method, entering the 7 day review process, or the chair can approve the amendment.

The UT IACUC employs the USDA pain and distress guidelines to categorize and review protocols. The following examples listed under the guidelines serve as reference points for the IACUC, OLAC and Investigators. Definitive category assignment is based on specific protocol review and committee approval.
USDA Category B:
- Breeding protocols (including genetic manipulations not expected to result in debilitating phenotypes and euthanasia of offspring prior to weaning)
- Holding protocols
USDA Category C:
No more than momentary or slight pain or distress and no requirement for use of pain-relieving drugs, or no pain or distress.
- Holding or weighing animals in teaching or research activities
- Observation of animal behavior
- Feeding studies that do not result in clinical health problems
- Routine physical examinations and diagnostic/treatment procedures such as injections, blood collections, cystocentesis, catheter implantation via superficial vessels (excluding cut-down of peripheral vessels), ultrasound diagnostics, radiographic diagnostics, fine needle aspirates of lymph nodes or masses
- Anesthesia/analgesia/sedation for restraint purposes for examination or routine minimally invasive diagnostic procedures such as5 above (excluding retro-orbital or cardiac stick blood collections).
- AVMA approved humane euthanasia procedures (excluding exsanguination)
- Routine agricultural husbandry procedures as outlined in the Guide for the Care and Use of Agricultural Animals in Research and Teaching (ex: ear tagging, freeze branding, subcutaneous implants in livestock, caustic paste method of dehorning, closed castration if <2mos and <230 kg)
