Abstract
This randomized control trial will determine whether financial incentives can be used to encourage caregivers to participate in online training programs. We will partner with Helping Restore Ability (HRA), a non-profit that supports thousands of caregivers in Texas, as they roll out a new online training program to improve in-home care quality. To encourage training take-up, treated individuals will receive emails offering a financial incentive for completing an online training program. Members of the control group will receive a standard email with no incentive for training completion. This study will determine the impact of this financial incentive on participation and performance in the training program.

Experimental Design

Experimental Design
This study will operate as a randomized-controlled trial. Approximately 750 caregivers will be randomly assigned to one of two groups: a control group, which will receive a standard email invitation to complete the training and a monetary compensation group, which will receive $50 for completing the training.

We also want to determine how many caretakers actually read the email we are sending. To determine this, we will include a line at the bottom of some emails that offers the caretaker a $10 gift card if they simply reply to the email. This line will be included in 150 randomly selected individuals in each treatment arm (i.e., 300 individuals total).
Experimental Design Details
Randomization Method
In this study, we use a rerandomization method in which all participants are randomized to treatment assignments 100 times. Of these 100 randomized datasets, we select the randomization assignment dataset that yields the minimum of the maximum t-statistic over select variables to ensure balance across treatment arms. These variables are gender, race, tenure with client, age, relation with client, tenure with HRA, employee relationship with HRA (Personal Attendant Services [PAS] or Consumer Directed Services [CDS]), an indicator variable for whether caregiver was on HRA payroll in September 2020, an indicator variable for whether caregiver is paid through Amerigroup insurance, indicator variables for whether (and how) the caregiver completed a pre-analysis survey, and an indicator for whether the caretaker used a training token (i.e., logged into the training platform) during a prior experiment offering training opportunities.

This approach is described in detail by Banerjee et al. (2020). Each of the variables used in the rerandomization process will be controlled for during analysis, as suggested in Bruhn and McKenzie (2009). 
Randomization Unit
Randomization will occur at the individual-level, using rerandomization method.
