Here is a pst file that will export names from PowerSchool for creating your CRS file for MaPs testing.
To use go to Special Functions - Importing / Exporting - Export using a template - Student Schedules - NWEA
Make sure you select the students you want to include or it will use ever student in your entire database.
This export will give you a good base but you will still have to go in a tweak your columns with some data.
