Certification is achieved through a rigorous, performance-based assessment that typically takes one to three years to complete.  As part of the process, teachers build a portfolio that includes student work samples, assignments, videotapes, and thorough analysis of their classroom teaching.  Additionally, teachers are assessed on their knowledge of the subjects they teach.  National Board Certified Teachers have successfully demonstrated advance teaching knowledge, skills, and practices.

The knowledge and skills developed by the teachers involved in the National Board Certification program are shared with new candidates, beginning teachers, and other teachers through the mentor process, thus improving overall teaching and learning in the district.  Currently, Hillsborough County Public Schools has 479 National Board Certified Teachers in the classroom.  This year three teachers achieved certification.  Also, this year 11 National Board Certified Teachers successfully completed the renewal process.
