Shadow Teacher® Day 2018 On November 12, the SLO® team organized the first Shadow Teachers® Day for this year. Shadow Teachers® are students who have been chosen by a teacher to help deliver the lesson. Two Shadow Teachers® are selected for each subject, and the position is held in high regard. Shadow Teachers® have many responsibilities including learning the concepts ahead of time to prepare in case a teacher is not present. More than 80 Shadow Teachers® had the wonderful opportunity to replace their teachers on that special day.
