I believe you’d need to manually add the Manage Users permission for your Agents Permission Group for you to reset someone’s password. This is not enabled by default for the Agent group, at least for us.  Once an Admin sets that permission you’ll be able to change a local user’s password by pulling up the user and clicking Change on the password field.

​@jo.cpa Thank you for submitting your question to our community!

First, I would suggest adding that permission policy ​@AJennings provided, without it, you do not have the permissions to reset their passwords. Are your parent/guardians brought over from your SIS or will they be all locally created users? 

I’m a Global Admin.  That is the permission is already applied via the default Policy.
I do not have an explicit additional policy applied.

I’m only trying to do this on Local iiQ Parents
 

​@jo.cpa 

I was looking into your districts installed apps, and I noticed you had password assist installed, that is the reason you are not seeing the change password option available there like other users are reporting there should be. Although I have not used this app much, ill attach a link to the knowledge base article on it! 

I’ve also started a ticket and asked for any support.
Can someone please work with me to resolve the issue?

​@jo.cpa What is the ticket number and I will follow up with support?

In the meantime, since you have parents coming over from SIS, this current workflow is not something we recommend. We do recommend parents use our Remote Support Ticketing and communicate via email. Here is a similar idea to upvote and follow: 

As mentioned before Remote Support Ticketing isn’t ideal for communications because the emails that go back and forth do not provide the Requestor with the information they need.  
Here is some feedback from senior members of my team.

In the meantime, I’ve spent a lot of time trying to get the Password Assistance app to work.
I’m a Global Admin.

I do not see the specified area in this below (from the link you provided -

In addition, I configured the Policy to allow Self Service as well as iiQ Admin to do password reset for iiQ Local ONLY

I do not see any method to reset a password as the iiQ Admin.  Nor does a Local Only (not SIS synced) Staff User have the ability do do a Self Service password reset.
