Hundreds of Washington-area teachers earned National Board Certification this year, adding to the area’s domination over other districts in Virginia and Maryland. This year, 71 teachers in Montgomery County achieved the certification, a result of up to three years of voluntary assessment scored on a teacher’s content knowledge, classroom videotapes, and narratives on their teaching philosophies. Montgomery’s 634 total teachers who have received the recognition places the district first in the state — more than double runner-up Anne Arundel’s 273 — and 12th in the nation.

Prince George’s came in third for Maryland with 267 board-certified teachers, including 76 new this year.
