Students were in Grades 8 enrolled in general education social studies or in Grades 7-12 and enrolled in general education English/language arts classes. Data were collected using measures of reading and other academic skills, attitudes, and student characteristics. All students participated for one school year only. The datasets include demographic information on students provided by their school districts in addition to the data collected by the study teams. The 2012-13 PACT social studies study was an intentional replication of the 2011-12 PACT social studies study. The master codebook provides details on the variables in each dataset. Note: All data is provided in long format, and as such each participant has multiple rows.
