  • There are very few schools with less than 40% of teachers who are fully credentialed, and because of small sample sizes, median API scores for schools with less than 40% credentialed teachers are erratic.
  • For schools with 40% credentialed teachers or more, there is a distinct relationship between the proportion of teachers who are fully credentialed and the API score: a higher API score is obtained by schools with a higher proportion of credentialed teachers.

Schools that are on traditional calendars have higher Academic Performance Index scores.
