The portfolio is a history of your high school career (grades 9 through 12) as you would like it told to employers, schools, or scholarship review committees.
Community groups will come to the high school to review your portfolio, and others will request it to be sent to a centralized location for consideration.
Submitting a portfolio does not guarantee an award. It also does not mean that you are applying for every scholarship available. The majority of scholarships have separate applications, and it is important for you to seek out those opportunities, complete the applications and send partial or full copies of your portfolio for consideration.
