The 2020 AASA Decennial Study of the Superintendent is an extension of national decennial studies of the American school superintendent that began in 1923. The research was conducted in late 2019 and early 2020. The results are presented in various ways throughout the study, ranging from aggregate findings to two and three level crosstabs that disaggregate data by eight different enrollment categories. Just as findings from previous decennial studies suggested, the various job-related happenings of superintendents are not always homogeneous. They can be influenced by a multitude of factors such as district enrollment, demographic characteristics of the superintendents, and characteristics of the students and communities they serve.
