Prerequisite Science Courses
Strong performance in science subjects lays the groundwork for advanced vet tech learning. These classes ensure you understand the biological processes behind animal health.
General Biology and Chemistry
Expect general biology with lab, covering cell biology, genetics, and animal physiology, paired with introductory chemistry to grasp medication dosages and reactions.
Anatomy and Physiology
Detailed study of animal anatomy and physiology is essential, including species-specific differences between mammals, birds, and reptiles.
Clinical Veterinary Procedures
Mastery of clinical procedures prepares you to assist veterinarians in diagnostics, surgery, and emergency care with confidence and precision.
Pharmacology and Medication Administration
You will learn drug classifications, dosages, side effects, and safe handling of controlled substances across different veterinary settings.
Diagnostic Imaging and Laboratory Tests
Training covers radiography, ultrasound basics, and running bloodwork, urinalysis, and fecal exams to support accurate diagnosis.
Animal Nursing and Care
Vet techs provide day-to-day nursing, requiring compassion, attention to detail, and strong communication with pet owners.
Surgical Nursing and Recovery Monitoring
Classes teach anesthesia monitoring, sterile techniques, surgical prep, and post-op care to keep animals safe during procedures.
Emergency and Critical Care
You will learn triage skills, fluid therapy, wound management, and how to stabilize patients in critical conditions effectively.
Externship and Hands-On Training
Practical experience in clinics or hospitals bridges classroom knowledge with real-world responsibilities under supervision.
During the externship, you will rotate through departments, observe surgeries, assist with client consultations, and build professional confidence.
Certification and Exam Preparation
Preparation for credentialing exams includes review sessions, mock tests, and focused study on regulations and professional standards.
- Complete all required classroom and clinical hours with strong grades.
- Use structured review programs for national and state certification exams.
- Practice mock scenarios to improve speed and accuracy in clinical tasks.
- Review ethical guidelines and communication best practices with clients and teams.
