Can't agree with you that 15 classes is full-time. In our district art
teachers can have a maximum of 25-1 hour classes per week, plus duties. That
is 5 classes a day or 5 hours of contact time with students. We have
teachers who have 2 buildings to make up the difference. For instance in my
main school, I had 19 classes the past three years and have had to travel to
another school to pick up the extra classes (anywhere from 5-2 more classes)
to make up the extra time. Also we count travel time...so depending on how
much traveling a teacher has to do, 30 minutes is given for travel and this
does count toward that 25 hours. I also have a total of 45 minutes of
duties each week, plus traveling.
Good Luck though with your job. I am sure it will be wonderful.
