First of all, be sure and follow the specific portfolio guidelines for each institution exactly as they indicate.  Adjust your portfolio according to their instructions — it is never one size fits all. If the school offers portfolio reviews, be sure to take advantage of that excellent opportunity for an “insider” view of your work. Present your portfolio in a professional manner and show a variety of skills. Admission Review Committees are often more impressed by your ambition and vision as they are by your drawing, painting, or photographic ability. Be sure to show your portfolio to a trusted art teacher to get an outside opinion of your presentation. Your portfolio may be best served by starting and ending with your best work.
