valedictio

Valedictio comes from Latin valedicere (to say farewell), from vale (farewell, be well) + dicere (to say). A valediction is a farewell speech. A valedictorian is the person who gives it. In American education, the title attached to the student with the highest grade point average, and the farewell speech became a reward for four years of academic excellence. The word does not mean 'best student.' It means 'farewell-sayer.'

The practice is American. British, European, and most other educational systems do not have valedictorians. The title emerged in the eighteenth and nineteenth centuries at American colleges, where commencement exercises featured a student oration as a central element. The top-ranked student was given the honor — and the obligation — of addressing the graduating class. The valedictory speech was in Latin at many colleges until the mid-nineteenth century.

The selection method has become controversial. Calculating class rank to the hundredth of a grade point generates intense competition and, some educators argue, encourages strategic course selection over intellectual risk. Some high schools have eliminated the valedictorian designation entirely. Others name multiple valedictorians — a mathematical contradiction that the word does not support. You cannot have ten farewell-sayers. One person says goodbye. That is the job.

The valedictorian is an American invention that other countries observe with curiosity. The idea that the best student should speak publicly, that academic rank should be announced at a ceremony, and that the farewell address should be delivered by a teenager — these are specifically American educational values. The word is Latin. The practice is from nowhere else.
