Classroom Rules

Punctuality- everybody's time is precious:

  • Be ready to learn by the start of class, we'll have you out of here on time
  • Tardiness: arriving late, late return after breaks, leaving early

The following are not allowed:

  • Bare feet
  • Side talking
  • Lying down
  • Inappropriate clothing
  • Food or drink except water
  • Phones in classrooms, clinic or bathrooms

You will receive one verbal warning, then you'll have to leave the room.
