This research utilizes a natural experiment design to explore geographical differences in Early Learning Development Standards (ELDS) completion amongst registrants, both before and after an online delivery option is made available. Registrants were geocoded by workplace, and the employment zip code serves as a clustering variable. Spatial hierarchical linear modeling was utilized to explore the predictors of attendance while accounting for the significant spatial clustering within the sample of registrants. Accounting for the spatial clustering in the HLM reduced the ICC by nearly 50%. Results provide evidence that before the online option was made available, registering for the training in the county of employment increased the likelihood of a registrant attending the ELDS training. In the post-online sample, registering for the online delivery results in a statistically significant 12% lower likelihood that those registrants will complete the training when compared to those registrants choosing weekend face-to-face delivery. With all other model predictors held constant, rural registrants were not statistically different in their likelihood of attending compared to either suburban/urban cluster or urban center registrants. Policy implications include the lack of change in rural registrants in the three months after online delivery, and the need for further qualitative research to understand any technical barriers faced by rural registrants in accessing online professional development. Additional policy implications include the importance of face-to-face training locations, and the critical nature of how rural is defined in a research study. Methodological implications include the utilization of spatial methods in research concerning rural education professionals.
