If it is as Pascale says, with nothing after "Avertissement", then I agree with her. I didn't read it as this to start with, but rather saw it as relating to the next line. Please confirm this Mary-Ann. Thanks!

See my answer to Helen's post, plus this link:

When we complete school reports, there is a printed form allowing for an 'avertissement'. Here, none was received, explaining the colon and blank space.

Après les deux points suivants "avertissement", il n'y a rien de noter. Ce qui peut vouloir dire que la personne n'a reçu aucun avertissement.
Ensuite, à la ligne suivante, la liste continue avec l'appréciation du chef d'établissement. C'est comme cela que je lis le texte. Attendons l'explication de Mary-Ann :-)

I don't really understand what you mean because following the word Avertissement there is a colon and then a positive comment from the Head, so in that case it cannot be a reprimand. Unless the heading Avertissement is in a separate section and does not relate to the Appréciation du chef d'établissement. Can you clarify this please Mary-Ann?

For a school report, I think avertissement would mean reprimand.
Explication en français: avertissement = remontrance. Exemples: Il sera renvoyé de l’école après trois avertissements. Recevoir un avertissement.

"Please note" serait correct pour "Remarque"
