Only if they had their Supernatural Virtues already when becoming apprentices. Or the artificial 'NPC version' had them.
This is not necessarily so. Apprentices p.10f Inherent Virtues provides the means to play apprentices, while allowing them to discover some of their Virtues during the game: like a Flambeau apprentice discovering an ArM5 p.43 Greater Immunity (Fire) during life with her Wrathful master. For an NPC apprentice this is just a SG decision. For a PC apprentice the player can choose it as an Inherited Virtue and thus retain more control over her character's development as a child.
See this thread, especially this post for the quote.
