Clary Carleton at Open High School was one of three Richmond Public Schools teachers recently awarded the prestigious National Board Certification, a program offered through the nonprofit National Board for Professional Teaching Standards. Program participants must develop a school-site portfolio of student work samples, videotaped lessons and reflective commentaries, and also pass test questions that demonstrate their subject matter knowledge. The program takes one to two school years and requires an additional 200-400 hours of preparation. [via]
