In many schools, seniors sit for formal senior portraits at the beginning of the school year or the summer prior to their senior year. These portraits are used in the upcoming graduating class' yearbook. The senior portraits in the yearbook are either in full color or black and white, but bigger than the smaller black and white pictures typically used for lower grades. Many modern yearbooks are in full color. Some may have a caption other than the student's name, or a quote from the student. There is a formal dance for this year's students, called senior prom; depending on the school, the junior class may host this dance for the seniors. Some schools hold a combined prom for juniors and seniors, while others segregate the two grades into separate dances. Senior skip day (also known as senior ditch day) is a day during which the seniors do not attend school and skip all their classes. This event/tradition is often not recognized by school administrations and teachers. In some areas it is countered with an officially recognized senior day off, or by allowing graduating seniors to skip their final tests ("final exams"). This official senior day can also be used to sponsor a "senior field trip" or "senior class trip" where the class would, for example, go to a theme park, a lake, a resort, the beach, or some other vacation-type activity. Following graduation, many seniors go on Senior Week, where they spend a week at the beach with their friends. Many seniors that are in the arts (but sometimes other areas), such as band or choir, will have the opportunity to go on an extended vacation following graduation. The students, faculty, parents, and other people may fund the trip through fundraisers, donations, etc. Travel usually involves going out of the local state, and possibly overseas. In some schools, Seniors receive a class ring at the beginning of their senior year. A "senior prank" is another common tradition in which the class may contribute towards a practical joke on the school, administration, or local community. A related tradition is the senior class either raising money or contributing money for equipment or other things to the school as a token of gratitude and respect for the school's support of the seniors. An example of this could be a senior class contributing money for a new weight room for the school or a state-of-the-art telescope for the science department. A similar project could involve the outside local community as well.
