How old are your cousins? Americorps seems to recruit (only recruits?) twenty-something, recent college grads. The people I know who've gone to work for them were certainly in that age group. Other teachers I know (15+ years of teaching) seem to have a fair amount of freedom in their lesson plans and materials so I wonder if this is an issue with Americorps, younger teachers, or perhaps I've just known some fortunate teachers.
