The term refers to the restrictions on calculator use during the Programme for International Student Assessment (PISA) examinations. These regulations vary depending on the testing cycle and subject area, sometimes permitting basic calculators, scientific calculators, or prohibiting them entirely. For instance, the 2015 assessment allowed scientific calculators for the mathematical literacy component, while the 2018 assessment had different policies for computer-based and paper-based tests. Specific examples of permitted devices are often listed in official PISA documentation to ensure fairness and comparability across participating countries.
Standardized assessments of mathematical literacy, like PISA, aim to evaluate problem-solving skills and the application of mathematical concepts in real-world contexts, rather than rote memorization or complex calculations. Controlling device usage helps ensure the focus remains on these core competencies. The evolving policies reflect ongoing discussions about the role of technology in education and the balance between assessing fundamental skills and the practical application of mathematics with technological tools. This controlled environment provides valuable insights into students’ abilities and informs educational policy development worldwide.
