Valedictorian is an academic title of success used in the United States, Canada, Central America, Singapore, and the Philippines for the student who delivers the closing or farewell statement at a graduation ceremony (called a valediction). The chosen valedictorian is often the student with the highest ranking (highest Grade Point Average, or GPA) among their graduating class. The term is an Anglicised derivation of the Latin vale dicere ("to say farewell"), historically rooted in the valedictorian's traditional role as the final speaker at the graduation ceremony before the students receive their diplomas. The valedictory address generally is considered a final farewell to classmates, before they disperse to pursue their individual paths after graduating.
In Australia, New Zealand, South Africa, Ireland, India and the United Kingdom, the title valedictorian is not used frequently. In Australia, the title is sometimes awarded to a member of a graduating university class on the basis of contribution to the school rather than academic success. The highest-ranking student in a graduating class is often referred to as dux (Latin for "leader"), and may or may not give a speech. In France the term Major de promotion ("first in class") is used, although the term is not related to any ceremonial role, as there are rarely graduation ceremonies in schools or universities.
How an individual school confers the title is typically based upon the highest grade point average. Some institutions confer the title on the class member chosen to deliver the final graduation address, regardless of the speaker's academic credentials. Historically and traditionally, however, schools confer the title upon the highest ranking graduate of the class, who thereby earns the honor of delivering the valedictory address.
Some institutions award the title based upon various criteria such as overall academic record of grades and credits, a student's grade point average, the level of rigor within a student's academic program of studies, a vote by school administrators, the level of participation in and dedication to extracurricular activities, and one's public-speaking skills and abilities. In other schools, the position may be elected by the school body or appointed directly by the school administration based on various systems of merit. Some schools may feature "co-valedictorians" in lieu of conferring the title on a single individual from among the graduating class. This may occur in the case of a numerical tie in grade point averages, as part of a Latin honors system.
A valedictorian is usually given the gold medal during the graduation ceremony, with the salutatorian receiving a silver medal.
The awarding of the valedictorian honor may be the subject of heated controversy. Often the differences separating the top student from the nearest competitors are small, and sometimes there are accusations that the winner took advantage of the rules in a way that seemed unfair, such as taking easy courses to get additional credits. Some schools have dropped the honor or changed the rules to allow multiple recipients. In turn, such changes have led to complaints that it is unfair to change the rules after a competition has begun. The New Jersey Commissioner of Education, for example, required schools to make changes to valedictorian award policy effective only for the incoming freshman class, not students already enrolled. Another New Jersey case raised the question of whether accommodations for students under the Individuals with Disabilities Education Act and related laws should affect valedictorian honors. In Hornstine v. Township of Moorestown, a U.S. District Court judge blocked the Moorestown Superintendent of Schools from retroactively changing school policy to deny a disabled student sole honors. Valedictorians even admit that the most intellectual struggle in school while valedictorians are the most hardworking 
The valedictory address, or valediction, is the closing or farewell statement delivered at a graduation ceremony. It is an oration at commencement (in Canada, called convocation in university and graduation in high school) exercises in U.S. and some Canadian high schools, colleges, and universities delivered by one of the graduates. The mode of discourse generally is inspirational and persuasive. The various aims of this address are to inspire the graduates and to thank individuals responsible for their successes while reflecting on youthful frivolity and the accomplishments of the class. Above all, however, the primary aim of the valedictory address is to allow a representative of the graduating class to bid a final farewell to the students and to the school, as the graduates prepare to disperse and to begin the next phase of their lives.
