Factors related to how student time is calculated in myLexia

This is the customer question:
 I just watched a child finish a session and log out with the red x. However, when I logged into my lexia, he still didn't have any minutes registered under his name. Does this mean if he wasn't logged out properly then the system needs to wait another 30 minutes and will then log his minutes? If his minutes never show up, what could be the problem? 

Lexia Customer Support response:
Thank you for contacting Lexia Learning.  Usage in myLexia is calculated based on students' time actively using the program and appears in myLexia once a student is logged out.  The minutes that appear in the teacher's myLexia usage reports can vary from the timer on the student's dashboard if they spend a few moments clicking the fun facts on the level dashboard or if they time out due to inactivity.  The server is pinged to track student activity whenever a student 1) completes a unit, 2) goes into guided practice, or 3) logs out of the system properly.  Even if they close the browser or the app, Lexia thinks they are still logged in.  If students don’t log out explicitly, the system waits for 30 minutes of inactivity to time them out and consider them logged out.  Minutes are calculated as login to logout - when students time out, their idle minutes are subtracted from the total time.  To see student usage reported more accurately, please encourage your students to log out explicitly (i.e., with the red X until they get to the dashboard; then they can click on the big white X).  You can also recommend that they remain working on a specific activity until they are able to complete a unit.
