PIRLS 2021 - Progress In Reading Literacy Study


Project duration: 01.03.2019 - 31.03.2023

Progress In Reading Literacy Study 2021

The Progress in International Reading Literacy Study 2021 (PIRLS/IGLU 2021) examines the reading competence of primary school pupils at the end of grade 4. Due to the layout of the study, the pupils’ competences can be compared to those from different countries and parts of the world. IGLU 2021 provides important knowledge in the context of international and national education monitoring.

Project description

The project Progress in Reading Literacy Study (PIRLS; nationally called IGLU) 2021 examines, based on representative data, the reading competence of pupils at the end of grade four in Germany. Due to the international design of the project, the German educational achievements can be compared to those from further countries and parts of the world. IGLU is a key element of educational monitoring in Germany, occurring for the fifth time in 2021. The study allows statements on trends in the school system and focusses on reading competence. Additionally, students’ key characteristics (e.g., reading motivation), instructional aspects (e.g., reading instruction strategies), school characteristics (e.g., half-day school or full-time school) and family characteristics (e.g., family preschool reading promotion) are taken into consideration and analyzed in connection to reading competence

Approximately 4000 pupils, their teachers and principals as well as their parents participate in IGLU in Germany. Important background information can be gathered in this extensive survey. In 2021, reading competence will no longer be assessed paper-based only but digital as well in Germany. Therefor pupils will also edit tasks using laptops. This supplement will lead to findings about the impact of digitalization on learning, especially in the context of reading in primary school.

The IGLU study is carried out in an interdisciplinary consortium of several German scientists (Educational Science, Subject Didactics German, Psychology), and in close agreement with international partners. Prof. Dr. Nele McElvany is the national scientific project director.
