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.

这项研究调查了参加PISA 2015年ICT熟悉度问卷调查的47个国家/地区中数学，科学和ICT规模的度量不变性。重要的目标是了解是否可以在不同国家之间可靠地比较相同的结构和度量。使用Alignment方法来测试这三个标尺的测量不变性。结果表明，数学和科学分数是高度不变的，可以用来比较各个国家，而ICT的规模大多是不变的，不能用来在所有参与国之间可靠地比较ICT的平均值。讨论了含义和局限性。
