The National Board for Professional Teaching Standards (NBPTS) is a private organization formed in 1987 with the goal of establishing standards for teaching effectiveness and certifying those teachers it identified as especially capable. NBPTS has written standards that purport to show what accomplished teachers “should know and be able to do” and has established a certification procedure that relies on videotapes, portfolios and written essays. There are currently more than 16,000 National Board certified teachers in the United States, more than 20% of them in North Carolina.
