This study examined the relationship between teacher demographic characteristics (race/ethnicity, age, and gender) and teacher summative performance evaluation ratings in a large urban district over three school years--2012/13-2014/15. In all three years a disproportionately large percentage of Black teachers, teachers age 50 and older, and male teachers were rated below proficient compared with their representation in the overall population of teachers who had a summative rating. However, from 2012/13 to 2014/15 the percentage of teachers whose ratings improved did not vary by teacher characteristics.
