Abstract: | This study investigates measurement invariance of the mathematics, science, and ICT scales across the 47 countries that participated in the PISA 2015 ICT Familiarity Questionnaire. Knowing whether the same constructs and measurements can be reliably compared across countries constitutes an important goal. The Alignment method is employed to test the measurement invariance of the three scales. The results show that mathematics and science scores are highly invariant and can be used to compare countries, whereas the ICT scale is mostly non-invariant and cannot be used to reliably compare ICT means across all participating countries. Implications and limitations are discussed. |
