The default subject order in Track My Progress is Math followed by ELA. When your students first sign-in to Track My Progress, they will be given the math test and when they sign-in the next day, the reading test will be administered. You can change this default order as a teacher if you have the necessary privileges. This will override the default order so that ELA screener is given first.
This differs from the Activity page assignments which you should use if you would like to assign a specific assessment type and subject to students. You can find the steps to complete that process here.
