Please thoroughly read the General CDE Rules Section at the beginning of this handbook for complete rules and procedures that are relevant to State FFA Career Development Events.
Purpose
The purpose of the Veterinary Science Career Development Event (CDE) is to promote college and career readiness by offering participants opportunities to cultivate technical knowledge and exhibit practical skills essential to the veterinary science profession.
Objectives
Participants will exhibit professional ethics, effective decision-making, clear communication, and problem- solving skills relevant to veterinary science practices.
Participants will demonstrate technical proficiency in both small and large animal care, focusing on:
Medical Terminology
Anatomy and Physiology
Species Identification
Clinical Procedures
Health and Safety Protocols
Veterinary Science

Event Rules
Team Composition
Each school may enter one team, consisting of up to four members, in this
To qualify for nationals, a team must have four members present and competing on the day of the contest. Teams with only three members may compete but will not qualify for nationals.
The total team score will be calculated based on all members’ accrued points.
Teams with two or fewer members will not be scored for individual or team placement and are ineligible to qualify for nationals.
Contest Participation
All contestants must participate in both practicum activities (refer to practicum rules for detailed information).
Dress Code
Contestants must wear clothing appropriate for handling and interacting with animals, emphasizing both professionalism and safety.
Required attire includes long pants and closed-toe shoes
Examples:
Jeans or khakis paired with a scrub top and
Scrub tops and pants paired with tennis shoes
Personal Conduct
Talking or discussion during the contest is not
Cheating of any kind is strictly prohibited.
Participants caught cheating, talking, or using unauthorized technology will have a red “X” marked on their scantron. While they may continue for experience, their scantron will not be graded, and their score will be recorded as 0.
Personal Devices
Cell phones and personal devices are prohibited during the contest.
Devices will be collected and stored in the team folder assigned to the participants' school.
If a student needs to contact a teacher or parent, they may temporarily retrieve their device from the check-in desk to make contact.
Equipment
Provided by contestants
#2 pencils
Non-programable calculator
Clipboard
Provided by contest superintendent
Official scanform
Blank scratch paper
ID reference sheet
Unit conversion sheets
Note: Any items brought by students, including calculators and clipboards, must be free of stickers, writing, conversion sheets, or any alterations. Students found to have altered their equipment will not be allowed to use it during the contest.
Event Schedule
The event will include multiple sections, with students rotating through four main stations and a designated rest station. Time limits for each section are strictly enforced to ensure a fair competition. Each station will have additional time allocated for instructions and material distribution. During the rest station, participants may use the bathroom but are prohibited from talking. Violations of this rule may result in dismissal from the contest.
Time limits for each section are as follows:
Written Exam – 40 minutes
Math Application – 20 minutes
Identification – 20 minutes
Practicum – 6 minutes per practicum (two practicums per contestant)
Contestants will complete all activities individually within their allotted time. The competition is designed to test their knowledge and skills across various aspects of veterinary science.
Event Components
Written Exam (150 Points)
The written exam is designed to assess participants' comprehensive knowledge of the veterinary science field. It consists of 50 objective, multiple-choice questions, including scenario-based questions. Each question is worth three points. Participants will have 40 minutes to complete the written exam.
Topics for the exam may include:
Animal Science Principles
Reproduction
Genetics
Welfare
Behavior
Anatomy
Physiology
Nutrition
Veterinary Science Principles
Disease Etiology
Epidemiology
Pathogenesis
Medical Terminology
Clinical Application
Clinic Management
Medical Records
Regulations (e.g., Federal OSHA, MSDS)
Patient Management
Facility Management
Math Application Exam (100 Points)
Participants will solve various math problems related to veterinary science. Participants will have 20 minutes to complete the exam and are permitted to use a non-programmable calculator. The number of questions will vary depending on the activity assigned and may include:
Unit conversions (including the metric system)
Dose calculations
Dilutions
Cost calculations
Invoices
Note: Unit conversion sheets will be provided to each participant during the math application exam.
Identification (135 Points)
Participants will identify equipment, parasites, anatomy, and breeds/species. Identification may include photos, live specimens, and actual equipment. ID sheets will be provided to participants at the start of this session.
The identification activity will last a total of 20 minutes. During this time, students will rotate through individual stations, spending approximately 30 seconds at each. After all participants have completed the initial rotation, there will be a brief review period where students can revisit certain stations they did not complete or mark.
The review period will be limited, and students will NOT have the opportunity to revisit every station.
To prepare effectively, students should practice completing identification within a 30-second timeframe.
The identification activity will include a total of 45 items (each worth 3 points) in the following categories:
Equipment: Identify various tools and equipment using actual items or photos.
Parasites: Identify parasites using photos or actual specimens, which may involve microscope usage (microscopes will be provided)
Anatomy: Identify organs, bones, and anatomical structures across animal species.
Breeds: Identify breeds of small and large animals using photos.
Practicums (50 Points each)
Each participant will complete two practicums, one focusing on ‘Handling and Restraint’ and the other on ‘Clinical Procedures’, worth 50 points each. The specific practicum will be announced upon arrival at the practicum activity.
Scoring for practicums
Each team member will complete two practicums: one focused on handling and restraint and the other on clinical procedures. Each practicum is worth a maximum of 50 points, for a total of 100 points per participant. The practicums are designed to evaluate both the participant's ability to perform the required skill and their ability to clearly articulate each step listed on the practicum rubric sheet.
Key scoring components
Clarity of explanation
Participants must clearly verbalize each step of the practicum rubric while performing the skill.
Judges will evaluate how accurately and clearly the steps are described, ensuring the participant demonstrates a thorough understanding of the procedure.
Proficiency in Skill Execution:
Participants are assessed on their ability to correctly and safely perform the skill, adhering to the rubric requirements.
Proper handling techniques, safety measures, and attention to detail are critical to achieving a high score.
Practicum process
Participants will have six minutes to complete each practicum.
Judges will observe and score participants in real-time, using the national FFA practicum rubric.
Practicum assignments are not revealed until participants enter the exam room.
Scoring breakdown
Articulation of Steps: Participants must vocalize each step as they complete it, contributing significantly to their score. Missing or unclear verbalization of steps will result in point deductions.
Skill Proficiency: Participants must demonstrate competency and adherence to the rubric’s standards. Errors in execution, safety breaches, or incomplete tasks will lead to point reductions.
Participants should thoroughly review the practicum rubrics and practice both performing and explaining the required skills to ensure they are prepared for both components of the scoring criteria. The practicum rubrics can be found on the National FFA Veterinary Science CDE website under “CDE Handbook” then “2023 Practicum Rubrics & Format” folder and in the appendix of this manual.
