CV stands for curriculum vitae. Another version is just saying vita. (But please don’t say “curriculum vita” or “vitae”. The Latin nerd in me can’t handle it!)
Your CV represents what you’ve done in your career. Therefore, you want to include relevant information with enough context so the reader has a good understanding of your experience. You should format your CV according to the position you are applying for – in this case, internship programs focus on clinical work, so your clinical experience should be included earlier in the CV.
There are many formatting examples you can find on line for CVs, but one thing to keep in mind is to learn how to use formatting tools (e.g., paragraph indent in Microsoft Word) so you can make edits easily in the future. Your advisors and supervisors will have their individual preferences, so you may hear different opinions.
