I teach Biology in a high school in Chesterfield County, VA.  I teach three levels: Honors, Regular, and Collaborative (with a Special Education teacher).  My Honors Biology class has 25 students, but my other two Biology classes have 28 students each.  Try doing biology labs with 28 students; in the Collaborative class 13 are special education students.  I also teach a Biology-2 class for students needing a 4th science credit, but who don't have the ability to take Chemistry or an AP class.  It also has 28 students - my classroom is always packed full.

I have a total of 131 students in 5 classes: many more than I've ever had in the past.  This means more papers to grade, more time spent at home doing school work, more IEP (Individualized Education Program) meetings to attend, and all for less pay and higher cost of benefits.

I can retire in 2 years, and unless things change, I will.  I would like to continue teaching, but it's not worth the time, effort, and lack of support from the community, school board, board of supervisors, and central office administration in Chesterfield.
