Effects of COVID-19 Pandemic on Progress Test Performance in German-Speaking Countries

Figure 3

Relative PT scores per semester. Each PT shares a considerable number of questions with the PT that took place five semesters prior; therefore, PTs conducted five semesters apart from each other can be naturally paired together (PT pair). Boxplots show an overview of the percentage share of correctly answered questions in each PT pair by students enrolled at nine faculties in Germany and Austria. Data are disaggregated by semester; plots in light gray refer to data from earlier PTs (36 = summer semester 2017, 37 = winter semester 2017/18, 38 = summer semester 2018), while plots in dark gray represent later PTs (41 = winter semester 2019/20, 42 = summer semester 2020, and 43 = winter semester 2020/21, respectively). For each semester and PT, the number of participants is indicated above the corresponding boxplot. PT, Progress Test.
