Here is an idea for improving attendance: give the teacher a digital camera with a tamper-proof time and date stamp and ask a student to take a photo of the teacher and class at the beginning and end of the day. Offer the teacher better pay for good attendance-verified by the photos. Will this work? A randomized comparative experiment started with 120 rural schools in Rajasthan and assigned 60 to this treatment and 60 to a control group.

Required:
(i) Outline the design of this experiment.
(ii) Label the schools and choose the first 10 schools for the treatment group. If you use Table B, start at line 108.
