Students dropping out of high school is a nationwide problem in the United States, plaguing communities and often greatly reducing the prospects of a quality life for those students who do not complete their high school education. The state of Louisiana consistently has among the highest public high school dropout rates in the United States and, often, the highest. This massive dataset of school variables covering a duration of five academic years (2014-2015 to 2018-2019) was originally compiled with the intention of identifying the factors that correlate with high school dropouts in Louisiana public high schools, specifically. However, it can be useful to any researchers interested in analyzing school-level data concerning a wide range of variables beyond merely dropout rates. This dataset also contains socioeconomic demographics, financial variables, class size, and much more. The correlation analyses ultimately revealed many intriguing insights into the relationships between the tested variables and the dropout rates. Dataset: The complete dataset, titled "A Dataset of Dropout Rates and Other School-Level Variables in Louisiana Public High Schools", is published here on Zenodo, an online data repository managed by CERN. The Digital Object Identifier (DOI) of this dataset is 10.5281/zenodo.6382661. Assuming normal connectivity, the Excel spreadsheet should take no longer than 30 s to download.
