Dahlem-Marienau – September 12, 2026 -- One in four 15-year-olds in Germany now fails to meet basic science competency standards, according to the newly released PISA 2026 study, which recorded the country's worst results since the assessment began. In response, private boarding school Schule Marienau in Lower Saxony is investing roughly €800,000 in a new STEM facility designed to reverse the decline in scientific literacy among students.
