Trends in International Mathematics and Science Study 2019 TIMSS 2019 marks the seventh cycle of the study and provides 24 years of trends. Conducted every four years since 1995, TIMSS has been a valuable tool for monitoring international trends in mathematics and science achievement at the fourth and eighth grades. TIMSS 2019 reported overall achievement, as well as extensive background information on the home and school contexts in which teaching and learning mathematics and science take place. Like the previous TIMSS assessments (conducted in 1995, 1999, 2003, 2007, 2011, and 2015), TIMSS 2019 collected detailed information about curriculum and curriculum implementation, instructional practices, and school resources. From the 2019 cycle onwards, an innovative computerized version of TIMSS enables countries to investigate complex areas of the mathematics and science framework that are difficult to measure with traditional paper and pencil tests. eTIMSS is an engaging, interactive assessment that encompasses the content of the paper-and-pencil version of TIMSS while also integrating problem solving and inquiry tasks designed to stimulate student motivation through items that simulate real world contexts and laboratory situations. In 2019, countries could opt to administer the paper-based version of TIMSS. The next cycle of TIMSS will be administered in 2023.
