Mathematics and Science Educators Earn
Advanced Teaching Credential


Moorestown, N.J., January 31, 2019 The Knowles Teacher Initiative today announced that six of its Fellows achieved National Board Certification, an advanced teaching credential that demonstrates their proven impact on student learning and achievement, in December 2018. Another Knowles Fellow successfully renewed his certification.  

Administered by the National Board for Professional Teaching Standards (NBPTS), National Board Certification involves completion of a rigorous, performance-based, peer-review process. Built upon National Board Standards and the Five Core Propositions, the certification process requires submission of a portfolio that contains evidence of differentiation in instruction, student engagement, and the candidate’s ability to act as an effective and reflective practitioner. Candidates are also required to demonstrate content knowledge through the completion of a computer-based assessment.

“Like NBPTS, we understand that teachers play a key role in improving education,” stated Nicole Gillespie, Knowles Teacher Initiative, President and CEO. “We encourage our Fellows to explore and refine their teaching practice through National Board Certification, and provide financial and mentoring support for them to do so.”

Through the Knowles Teaching Fellows Program, early-career, high school mathematics and science teachers receive five years of support designed to help them develop teaching expertise and lead from the classroom. After completing the fifth year of the Fellowship, Teaching Fellows become Senior Fellows who have the opportunity to remain involved in the Knowles community throughout their careers and be supported in ongoing leadership efforts. Knowles Fellows pursuing National Board certification also have access to dedicated funds that can be used to pay for application fees, to purchase a video camera or to cover other relevant expenses.  

The following Knowles Fellows achieved National Board Certification:

Knowles Senior Fellow Charley Sabatier—Oxford High School, Oxford, Mississippi—who was first Board Certified in 2008, renewed his certification by submitting a Professional Profile of Growth demonstrating how his practice continues to align with the Five Core Propositions.

Nationwide, more than 122,000 teachers have achieved National Board Certification, including 35 Knowles Fellows.
