Hello Artist4hire,
Be sure to have a strong password that they cannot guess created for each administrator account you have on the computer. They will not be able to change their account type without having to enter the administrator password first. Be sure to enable the built-in Administrator account and give it a password to prevent them from trying to use it as a backdoor to do this.
How to create a password for a user account:
User Account - Create Password
How to enable the built-in Administrator account:

In addition, you might check out Parental Controls to use on their Standard account to help control what they can use to. This tutorial will help show you how to.

Hope this helps you,
