PIRLS Literacy 2016 International Database: Progress in International Reading Literacy Study

PIRLS provides trends and international comparisons of fourth grade students’ reading achievement and students’ competencies in relation to goals and standards for reading education. In addition to reading assessment, the PIRLS school, teacher, student and home questionnaires gather extensive information about the contextual factors at home and school which are associated with the teaching and learning of reading.
In 2016, IEA and its TIMSS and PIRLS International Study Center at Boston College conducted PIRLS 2016 at the fourth grade.PIRLS 2016 consists of three separate assessments of reading comprehension:
PIRLS, PIRLS Literacy, and ePIRLS. PIRLS 2016 provides 15-year trend measures for countries that participated in the first PIRLS assessment in 2001. ePIRLS, an innovative assessment of online informational reading, launched its inaugural cycle in 2016.
Matching PIRLS for breadth of coverage but with less difficult reading passages and items, PIRLS Literacy (formerly prePIRLS) extends the effective measurement of reading comprehension at the lower end of the PIRLS achievement scale.
