Taking a college entrance exam such as the ACT™ or SAT™ can be an important step in the college-going process. Although overall, 1 out of 10 students who register for the ACT on a national test date are absent on their registered test day, the absentee rate (at 21%) for students who registered with a fee waiver is substantially higher than the absentee rate (at 5%) for students who paid the registration fee. The current study examined whether a brief telephone reminder of the test date an of the required test materials a few days prior to the test date would result in fee waiver students having higher test day attendance rates. Using a randomized control trial with 2,500 students, the findings of this study do not provide evidence that the treatment as delivered had an impact on the attendance rates of fee waiver students. There are several possible rationales for why the treatment was not effective, and these rationales point to areas of future direction for this research initiative.
