TEI Myth: TEI is needed to identify highly effective teachers.
FACT: Master teachers and principals are capable of identifying the most effective teachers.
- The initial cohort of ACE teachers were identified by principals six months prior to calculated TEI ratings, thus TEI was not a factor.
- In 2016-17, only 31% of the ACE campus teachers were deemed "highly effective" and their average teacher retention was only 69%.
