About PIRLS

PIRLS 2026 Scotland
Progress in International Reading Literacy Study
National Research Centre for Scotland

The Progress in International Reading Literacy Study, known as “PIRLS”, is an international comparative study that assesses and compares the reading performance of pupils at about age 10, or P5 in Scotland, every five years across about 60 countries. This is the first time Scotland have taken part in PIRLS since 2006. It provides internationally comparative data on pupils’ achievement in reading, and how their performance is related to their attitudes, gender and background. In addition, PIRLS includes questionnaires for teachers, headteachers and parents/guardians, which provide a valuable perspective on teaching reading, and the school and home environment.

What does PIRLS consist of?

PIRLS consists of five components in Scotland:

  • An onscreen reading assessment for pupils.
  • A background questionnaire for pupils.
  • A questionnaire for teachers.
  • A school questionnaire for headteachers.
  • A home questionnaire for parents/guardians
