Student Goal Objectives

The students learning in one year can lag behind for as long as 11 months if they are unlucky to stumble across ineffective teachers. Realizing the importance of the teachers' effectiveness, NJ government has introduced SGOs (student goal objectives) for teacher evaluation. Of course, lots of backlash from incumbent teachers, citing the murky evaluations of teachers on subjective goals in SGOs. That being said, does it mean every teacher can run their own course without being evaluated by some criteria? (and leave students to their own devices?)
