New York State United Teachers, the state’s largest teachers union, launched a campaign against what it calls “obsessive” standardized testing in New York schools, reports the Syracuse Post-Standard. It placed a full-page ad in a number of papers yesterday, arguing that teachers and students have not been given enough time to prepare for new third- through eighth-grade exams, the first state exams aligned with the Common Core, scheduled for mid-April. The state plans to use the exams to measure student progress and evaluate teachers, while the union thinks this year’s tests should only be used to evaluate how well schools are adopting the new standards.
