Interactive Achievement is now PowerSchool Assessment

Interactive Achievement (also known as OnTrac) has been bought by PowerSchool LLC.
InterActive Achievement(IA) and/or OnTrac is now PowerSchool Assessment.
The new Longitudinal Data Systems(LDS) is now PowerSchool Analytics.
PowerSchool has grouped the two together as PowerSchool Assessment and Analytics.
The registration email email from IA and/or OnTrac sent to  teachers now comes from aapowerschool.  Those emails have been sent to all users  who has an email address in PowerSchool (student information system).
There are instructions in the email to register your account.  Teachers and IA administrators need to register their account (follow the directions in the email)
Once your account has been registered, you will see your students and classes in PowerSchool Assessment & Analytics.
Those who have been given access to the "LDS" side; Analytics will have that access as well.
Teachers will see students if they are assigned as the teacher of record for students.  Others (school health assistants, secretaries, etc) who may receive this email should just ignore it.  If an account is created; there is no information avaialble to you.
