Fifty countries from around the world participated in the Progress in International Reading Literacy Study (PIRLS) 2016 international assessment of reading comprehension at the fourth grade, and in every country there was a wide range of reading achievement from basic skills to advanced comprehension. This report presents international findings from PIRLS 2016 fourth grade. In terms of basic reading literacy, it is noteworthy that in more than half of the PIRLS 2016 countries almost all of the students (more than 95 percent) demonstrated fundamental reading skills. These students could locate and reproduce ideas and information from text and make straightforward inferences. [For the primary report "PIRLS 2016: International Results in Reading," see ED580353.
