"Why does the progress bar jump?"
Each participant will see a progress bar on the top of each page as they go through the survey.
This shows how many questions the participant has left to complete on the survey. However, this bar does not move or go up after each finished question, it only goes up after each finished page. This means that the time bar may go up a lot for one a page that contains many questions but only a little for a page that contains only a few questions.
"How long does it take to complete the survey?"
The average amount of time required for a student to complete a survey is different for each school district. The survey should not take longer than a single class period to complete. For a more specific estimate of survey completion time for your district, please consult your District Coordinator.
