Documenting CVTEA skills is time consuming
The CVTEA requirements indicate that an accredited Vet Tech school must document their student's progress within the list of essential skills. The essential skill list includes hundreds of tasks and when you multiply that times the number of vet tech students in your program you've quickly got a large job on your hand just documenting skills for accreditation.
Many programs are still using pen and paper to track each student's progress with the CVTEA essential skills. Recording student essential skills progress on paper has some big drawbacks: skill tracker binders get lost, accountability is unclear, and you have to somehow store all the completed binders for years after the student has graduated from your program.
