The classes range in size from 60-120 with average attendance around 90. This year, so far, we've been on track with those numbers, with 90 at DU, 155 at CU, 65 at Casselman's, 75 at Colorado College, and around 80 at Bent Gate.
Our largest ever was 180 at the Oriental Theater last year. (Incidentally, we just added a class Wed 1/19 at the Oriental) Our smallest was 5 in Breckenridge several years ago, if you're wondering why we haven't been back to Breck.
Our field days are limited to 75 participants per day, including instructors. We try to maintain a student teacher ratio of 3:1 to maximize the experience and to minimize our footprint.
Our yearly total hovers around 1,200 but our goal is to hit 2,000 by 2012. The field days will always remain small, however in the future we may add more dates.
