The appearance of multiple percentile lines has to deal with the adjustment of your benchmark date range settings. When starting a new academic school year, all of the dates in the benchmark date range settings must be reflective of the current academic school year. So the fall scores need to reflect the current year, and the winter and spring should have the upcoming, or next year’s date in them.
To access this feature, first login to your account and go to the “Admin” tab. Next locate the “Account Management” section and click on System settings. Now, scroll down to the Benchmark Window Settings. To adjust this setting, select the opening and closing dates for the testing window. The benchmark window needs to be current for testing and the remaining benchmark dates need to be staggered with only one testing window open at a time. After selecting the dates, please make sure to click on the “Update Benchmark Dates” button in order for the changes to take effect. An example of correct benchmark window for the 2018-2019 academic year is:
Fall Sept. 1 – Sept. 30, 2018
Winter Jan. 1- Jan. 31, 2019
Spring April 1 – April 30, 2019
