The National Board for Professional Teaching Standards announced last week that 4,980 teachers earned certification last year, pushing the total number of educators who hold the advanced professional certification to more than 100,000.
In its announcement, the board also highlighted a recent report by Harvard University’s Center for Education Policy Research showing that teachers with national-board certification in Los Angeles outperformed their peers on the basis of student standardized-test scores in math and English.
The Arlington, Va.-based organization reports that national-board-certified teachers are now in all 50 states, with the largest numbers in North Carolina, Washington state, and Illinois.
