The Progress in International Reading Literacy Study (PIRLS) is a global assessment that measures the reading skills of fourth-grade students. Conducted every five years, it evaluates how well students understand and interpret written texts. The study provides valuable data on educational practices and outcomes across different countries, helping to identify effective teaching methods. PIRLS is coordinated by the International Association for the Evaluation of Educational Achievement (IEA) and involves participation from numerous countries worldwide. The results help policymakers and educators improve reading instruction and literacy rates, ultimately aiming to enhance students' reading proficiency and comprehension skills.
