Old method used in the Ecoles Françaises (French school in Barcelona) to promote the best students of the month. As in our very Everything, students would receive positive or negative votes (from the teachers), based on their performance, attitude, punctuality, etc. Along with the names of the best students, blue pins (positive votes) and red pins (negative votes) where shown in the Tableau d'Honneur.

I discovered this while proselytizing Everything to an old student from the Ecoles Françaises. She got it at once: "this is is like the Tableau d'Honneur!."
