I'm a first year teacher and I've heard stories of how you stay so late after school your first year. I was just curious how late , no matter how long you've been teaching do you stay after school? So far the longest I've stayed in my classroom is 6:30. On Fridays, I try to leave around 4:15 or 4:30. I have had later days for off site meetings and trainings where I didn't get home until 8:30.
