Instructor Training Stats

This post originally appeared on the Software Carpentry website.

The Software Carpentry Foundation's board asked me for some stats on instructor training, and I thought other people would find them interesting as well:

• In the year Nov 1, 2013 - Nov 1, 2014, our numbers were:

  instructors:	360
  helper:	163
  learner:	3914

  That gives us an 9:1 ratio of learners to instructors, but the reality is probably closer to 10:1, since we have all the instructors in our database but are still waiting for some recent workshops to report headcount. Note that "instructor" counts every time a person taught a workshop, including repeats, and similarly for "helper" and "learner". Note also that this significantly under-counts helpers, since they're often not reported or recorded.

• Since September 2013, but not including the recent live round at TGAC and University of Washington, or the current online round:

  started:	356
  completed:	98	(27.5%)
  incomplete:	163	(45.7%)
  in progress:	95	(26.7%)

  Note that half of those who drop out do so in the first four weeks. Note also that some people have been "in progress" for months, but even a few of those do eventually complete...

• 89 people who got their instructor badge after Sept 1, 2013 have taught for us, out of 126 who have been badged in that time. That's 70%, and the number will climb as the people who have been badged in the last three months (summer online training, TGAC, and U. Virginia) start teaching.

• Of the people signed up for online instructor training in January 2015:

  66	US
  17	UK
  15	Canada
  12	Spain
  12	Australia
  5	unknown
  3	Brazil
  2	Netherlands, South Africa, Switzerland
  1	Chile, China, Colombia, Germany, Ghana, Hungary, Ireland, Israel, Italy, Japana, New Zealand, Poland, Saudia Arabia, Singapore, Turkey

  and:

  female	38	(25%)
  male	113	(75%)

  That last statistic is better than the gender balance among our current instructors (20% female), but still much lower than where we were a year and a half ago (38% female).
