This project used a subset of data collected as part of Project iLEAD (in-school longitudinal executive function and academic achievement database). We are making the data and scripts used in Younger et al., 2023 publicly available, with a small edit to help protect the privacy of the students that participated in this research. While the analyses used age in months to characterize participant age, we are publicly providing the courser data of age in years. As such, some statistics will not replicate exactly. Additional data collected as part of project iLEAD, including the participant age in months is available upon request and upon agreement to maintain data privacy and security, including the stipulation that the data NOT be published in any form elsewhere. Descriptions of additional available data can be found in the Project iLEAD Data Dictionary folder. To request additional data, please use the following google form and one of our team members will contact you with next steps. https://forms.gle/UFj5dLwcrUi42beT8
