PISA 2018 Results (Volume III)

Annex A5. Interpreting the results by student and school characteristics

Reporting thresholds in PISA 2018

When presenting the results by students’ gender, socio-economic status, education level and immigrant background, and schools’ socio-economic profile, location, type and concentration of immigrant students, the number of students and schools in each subsample has to meet the PISA reporting requirements of at least 30 students and 5 schools. Even when these reporting requirements are met, the reader should interpret the results cautiously when the number of students or schools is just above the reporting threshold. Tables III.A5.1 and III.A5.2, available on line, show the unweighted number of students and schools by student and school characteristics in the PISA 2018 sample so that the reader can interpret the results appropriately.

Reading performance, by student and school characteristics

Tables III.A5.3 and III.A5.4, available on line, show the average reading performance, by student and school characteristics. These results provide useful information for interpreting the analyses in this volume that show how the school climate and well-being indicators vary by student and school characteristics.
