The thing about CC is that at the level I taught it was not
developmentally appropriate. In the state that I taught in, NYS, the
assessments are tied in to teacher pay and retention. At the state level, the assessments are used to punish poorly performing schools, which I read as low income schools, by reducing state funding. There are many threads here but in a corrupt state like NY it ties into huge contracts for curriculum and testing along with privatization of poorly performing public schools. This in a state which had a good curriculum and was about to adopt its own higher standard curriculum but got swept up in the Federal plan. I'm not married to the Unions on this a lot of the funding difficulty comes from the gold plated retirements of current retirees and those who are about to retire. The teachers behind them are largely screwed though, which is leading to a reduction of satisfaction and more retention problems. The "modules" which teachers are encouraged to use do not allow for flexible teaching styles where you pursue the interests of the students to enable learning. The teachers are expected to become automatons, which may be fine considering the quality of teacher they'll be left with.
My current position is outside the education system looking in. I work to improve the behaviors of a caseload of kids mostly on the spectrum by teaching parents how to support their children's needs. Some of these kids are very intelligent. What I see is that these children's needs are not being met in schools. Children who tend to carry a lot of anxiety don't generally fair well with long hours of testing. I had a girl on my caseload flee and hide during the ELA testing. I see increased anxiety and parents trying to decide if opting out will prevent their child from graduating and going to college.
7% of students with IEPs passed the CC math for 3-5 grades. Too many threads to write about right now, but there are a ton of issues. The main one for me is this, "Are the civil rights of children with special needs being violated?"
