To Access NISD NetSchool CLICK HERE. Use the search box at the bottom of the NetSchool page to search for a specific teacher or class. All NetSchool courses may be visited by guests (those who do not have a login); however, guests may not participate in forums or upload documents. Guest access is available to all NetSchool courses, but you have to search by teacher. If you log in as your child, you will have access to all of your child’s course content.
