TIMSS and PISA are international assessments that evaluate student achievement in mathematics, science, and reading. TIMSS focuses on mathematics and science achievement every 4 years and collects data from pupils, schools, and teachers. PISA assesses reading, mathematics, and science literacy every 3 years and collects additional data on pupils and schools. Both studies provide insights to help countries understand factors that influence student skill development and inform education policy. Participating in these studies benefits Malaysia by allowing international comparison of student performance and identification of best practices that could improve education.
