I'm curious as to how many of you work in schools that have classrooms leveled by student achievement/ability? Our district tries to have heterogeneous classes, with a mix of gifted, high, average, low, and special ed students in each. While I find this admirable, and useful in some ways, I also have worked in districts that either had leveled classrooms or leveled during reading and math classes, and this also had its advantages. So how does it work where you are? And what are your feelings about this often volatile subject?
