Is National Board Certification An Effective Signal of Teacher Quality?


"Although there is general agreement among policymakers, educators,
and researchers that teacher quality is key to student success,
there is less agreement about the contribution that specific professional
attributes make to good teaching. This paper examines nearly
108,000 individual student records collected from Miami-Dade
County Public Schools to assess the contribution that teachers' professional characteristics make to student achievement in mathematics in the ninth and tenth grades.

In this study, National Board Certification (NBC) proved to be an effective signal of teacher quality.
Indeed, seven of nine indicators of teacher quality that were included
in the analyses resulted in appropriately signed and
statistically significant evidence of their influence on student outcomes.
Among those indicators, having an in-subject-area teacher,
NBC and regular state certification in high school mathematics had
the greatest effects."
