The Internet has become the primary source for obtaining information at work, at home, and for school. Because Internet reading increasingly is becoming one of the central ways students are acquiring information, in 2016, PIRLS was extended to include ePIRLS--an innovative assessment of online reading. ePIRLS is a computer-based assessment that uses an engaging, simulated Internet environment to present fourth grade students with authentic school-like assignments involving science and social studies topics. Like PIRLS 2016, the ePIRLS assessment was developed based on the "PIRLS 2016 Assessment Framework," used the same quality assurance procedures, and was given to the same students who participated in the PIRLS assessment typically on the next day. The ePIRLS assessment consisted of five tasks with each task lasting up to 40 minutes. This brief report presents an overview of ePIRLS 2016. [For the "PIRLS 2016 Assessment Framework," see ED545242.]
