This brief is an addendum to the May 2018 PERC report, Getting on Track to Graduation. Focusing on two cohorts of first-time ninth grade students (the Classes of 2019 and 2020), Getting on Track to Graduation examined the extent to which students earned the required number and type of course credits to be considered on-track to graduation. This brief extends analyses from the previous report with data from two additional cohorts of first-time freshmen (the Classes of 2017 and 2018) to better understand whether the patterns described in the original report have been consistent over time.
