Why Are Gen Z’s Test Scores Falling?

The world’s largest international study of 15-year-olds has revealed a worrying decline in science, mathematics and reading scores, raising questions about how well teenagers are mastering core academic skills.

The findings span three central areas of education rather than a single subject. Together, they point to a broad challenge for schools seeking to strengthen both literacy and scientific and mathematical understanding.

The summary of the findings does not identify what is driving the decline. Without further details, it is not possible to attribute the results to any particular teaching approach, change in study habits or wider social trend.

Although the results raise concerns about Generation Z’s learning, the study focuses specifically on students aged 15. Understanding the scale and causes of the downturn will require a closer look at the full findings, including how performance varies across education systems.
