Externship, Internship and job inquiries and applications typically require you to submit a resume or CV (curriculum vitae) to the employer or organization of interest. 

In most cases, the application instructions for the position you are applying to will specify whether a CV or resume is being requested. If this information is not provided, you will need to determine which of them most appropriately fits the criteria provided by the employer or internship committee who will be reviewing your application.

Please note that employers sometimes confuse the terms and use them interchangeably. So, if you are in doubt—the general rule of thumb is that if you are applying for a veterinary associate position you should submit a resume; if you are applying for an externship, internship or a position in academia (research or clinical) you should submit a CV.
