As students settle into their first months of the new school year, it's a good time to check in on the teacher policy landscape governing the profession across the country.  From new college- and career-ready standards to changes in evaluation systems, many states are making progress towards ensuring that all students have effective teachers. Currently, all but ten states require that at least some objective evidence of student learning is considered when evaluating teacher performance.  And with so many new teachers just beginning their careers, it's good to see that 31 states require mentoring for all new teachers and 26 have strong  overall induction policies , unless of course you are a new teacher from one of the many that don't.
