In this white paper, we present results from two rounds of an experiment of tokens of appreciation. In the spring 2021 round of the experiment, we tested the use of prepaid tokens of appreciation by randomly assigning centers to one of two treatment groups for staff (including select center administrators and all teaching staff) to complete a 15-minute time-use survey. In one group, survey respondents received a prepaid amount of $10 and a postpaid amount of $10; in the second group, respondents received a postpaid amount of $20, and no prepaid token of appreciation. The prepaid token of appreciation resulted in a 20-point statistically significant increase in the response rate (81 percent compared with 61 percent) over the postpaid token of appreciation alone. In fall 2021, we administered a second round of the experiment to test different prepaid amounts for a 45- minute teaching staff survey. We tested a prepaid amount of $10 and a postpaid amount of $40, versus a prepaid amount of $25 and a postpaid amount of $25. The response rate for the lower prepaid and higher postpaid amounts was significantly higher than the response rate when the prepaid and postpaid amounts were even (93 percent compared with 87 percent).
