A college portfolio has slightly different components from university to university. It usually comprises 10 to 12 original artworks that best illustrate an artist's capabilities. Students typically store those artworks in a large black, zippered portfolio that keeps them safe while traveling. A student might also include a sketchbook featuring their current work.
Photos of all of these elements together are often uploaded into a digital portfolio. Each university has different platforms to which these artworks can be uploaded.
I've only experienced this via the program at Virginia Commonwealth University in Richmond, Virginia. The way it is performed there, is registered high school students come on a single day to a venue (in VCU's case, at least two buildings). It is set up more or less like a conference, with tables containing representatives from the various colleges.
Contests
For years I managed this program in my county. Students create Visual Arts and Photography entries with an annual theme; “What My Culture Means to Me” is the theme for 2026-2027.
Note: There is another program called a PTO, and high schools with this program are not eligible for this art program
I've been to the awards ceremony for this program. Individuals who have a rare disease (or a family member with one) are eligible for this art contest.
Our daughter and some of my students have participated and won awards in this long-standing contest.
Our son and others in our community have participated in this competition. It results in art being displayed in certain public places.
