For security reasons we cannot show the entire school listing of students to a teacher to choose from. Teachers will need to have the list of GTIDs for the students in the class in order to search and acquire. The students are not assigned to a teacher in any way via the roster import.
Here are the steps you need to follow to help your teachers:
To quickly acquire students to place in teachers' accounts the school administrators will :
Click Teachers from the left menu
Click on the desired teachers name
Click the green Add or Acquire button
Select students for the teacher, click the acquire button to the right of each student's name.
