The number of minutes and clips of video recording vary by discipline. The best source of information about minutes and clips is the description for Task 2 in the handbook. Nevertheless, all areas are permitted either 15 or 20 minutes of video instruction. Elementary literacy, elementary mathematics, and secondary mathematics may submit one clip up to 15 minutes, or two clips totaling up to 15 minutes. Alternatively, English language arts, performing arts, and secondary science submit two clips, totaling up to 20 minutes. And again, health education and visual arts may submit one clip up to 20 minutes or two clips totaling up to 20 minutes. All of the disciplines shown here include two optional clips. Candidates may include a three minute clip showing student voice and a five minute clip showing academic language. Optional clips do not contribute to the totals associated with instruction clips. For example, a portfolio in visual arts may include one 20 minute clip showing instruction, another three minute clip of student voice, and another five minute clip of academic language, for a total of 28 minutes.
