I am currently administrating the development of a charitable organization that recognizes the merits for primary (and potentially secondary) students in achieving perfect attendance throughout the school year.
With this ambition in mind, we are committed to establishing a suitable name and motto for the organization that would encompass the multi-cultural presence of the educational institutes, as well as portray the dignity and prestige of the awards. We feel the use of the Latin language would achieve these objectives.
What would be an appropriate translation of "perfect attendance" in Latin?
Thank you in advance.
