• The Marshall Memo Admin - Issues

  • In 2009, TNTP reported that teacher evaluation systems didn’t accurately distinguish among teachers with varying levels of proficiency, failed to identify most of the teachers with serious performance problems, and were unhelpful in guiding professional development.
  • The Widget Effect study concluded that “school districts must begin to distinguish great from good, good from fair, and fair from poor.”

  • On average, only 2.7 percent of teachers were rated below Proficient/Exemplary on a 4- or 5-point scale.

     

  • The percent of teachers given the top rating ranged from 73 percent in Tennessee to 8 percent in Massachusetts and 3 percent in Georgia.

     

  • Many districts are drawing important distinctions between good and excellent teaching, but there is less differentiation among good, fair, and poor performance.
