Hi, Juli!
Don't worry - a lot of people have this problem at this time of year! The surest way to make sure students don't sign up for Teacher accounts is to
add students directly to the Roster and then give them a direct link to your class (not to
my.haikulearning.com or
myhaikuclass.com). An
Open Invitation will also work, but there's a little more risk that a student could accidentally end up in the wrong place.
Basically, as long as you create the student accounts yourself
or as long as the students create their own accounts through your class Invitation, they won't be able to sign up for Teacher accounts. But if they go directly to
my.haikulearning.com or
myhaikuclass.com and create their accounts there, they
can create Teacher accounts.
All in all, it's not a huge problem if students end up with free Teacher accounts, as long as they're listed in your class in the Students part of the Roster. With Teacher accounts, they can make classes of their own, but in your class they'll only have Student permissions if they're listed in the Students section of the Roster.
If you have further questions, or if you have some specific cases you'd like us to help you with, I'd recommend submitting a help request at
support.haikulearning.com.
Have a great day!
Cheers,
Justin
