While I support the idea of a common set of standards nationwide, I feel the CCSS as they are need to be adjusted, especially in the lower grades, to fit student developmental levels. Also, although publishers and testing companies are using CCSS to NARROW their curriculum and content, common standards shouldn't limit learning... teachers allowed to use materials, lessons, etc. of their own choice can still integrate common standards without being restricted in overall content.
Additionally, I am firmly against standardized testing... which is truly the "one size fits all" Procrustean bed. I teach special education. I have high expectations for my students. Standardized testing doesn't measure their growth, because a student who, in 4th grade, starts my program just learning to read, and by March is reading at an early 1st grade, is going to get the same score regardless, because he or she is still guessing since the reading is still so far above his/her level. Standardized testing also doesn't give any data to drive instruction. It is too vague, to minimal, and often reported at the start of the next school year when the child's knowledge levels are no longer at the same place they were during the test.
Yes, as a teacher, I AM accountable... to my students and their parents, not to some weird set of statistics that have nothing to do with my actual teaching ability or my students' needs.
