I dunno about America, but in the UK we start refering to our teachers by their first names in Further Education (What we would call College or Post 16 but Americans I guess would call High School.) And Beacon gives me more of a Uni (College) vibe anyway.

Besides, they are talking in confidence to eachother, not addressing their teachers directly.
