Students working on a school assignment or research project will finish sooner if they focus on finding critical information and are not distracted. To collect information about this, a number of the webpages in ePIRLS contained advertisements. Almost identical to the results in Exhibit 4.1, 92 percent of the students remained focused and did not click on any advertisements (average achievement of 542). Eight percent did click on at least one advertisement and had lower average achievement (512).
