What Google Classroom add-ons are
Google Classroom add-ons are third-party tools that integrate with Google Classroom using Google’s official Classroom API. They allow external services to interact with your classes — reading class lists, posting assignments, or adding features that Google Classroom does not provide natively.
For teachers, add-ons expand what is possible without leaving the Google ecosystem. The key question is always what the add-on does, what access it requires, and whether a school IT department or DPO needs to approve it first.
What teachers most commonly look for
When teachers search for Google Classroom add-ons, the most common gaps they are trying to fill are:
- Recurring assignment scheduling — setting a pattern so the same assignment posts automatically each week or term
- Bulk content management — importing or duplicating content across multiple classes
- Assessment integration — connecting quiz or assessment tools to Google Classroom gradebooks
- External platform reminders — posting timed reminders for third-party learning platforms like Tassomai, Seneca, or Sparx
Class Add-Ons: a scheduling add-on for Google Classroom
Class Add-Ons Scheduler is a scheduling tool that connects to Google Classroom through the official API. It focuses on one thing: making it possible to schedule recurring assignments, reminders, and classwork with due dates, attachments, and email alerts.
It is designed for the gap Google Classroom leaves around recurring posts. Teachers create a scheduling task — title, instructions, recurrence pattern, due date, and attachments — and Class Add-Ons handles each subsequent publication.
Access and permissions
Class Add-Ons uses Google OAuth and requests only the permissions needed to schedule and post classwork:
- View your Google Classrooms
- Post classwork on your behalf
It does not request access to student records, grades, email accounts, or passwords. Access can be revoked from your Google account at any time.
Data and privacy
Class Add-Ons does not store student data or passwords. It is designed to meet the data expectations of UK schools: no student records saved, GDPR-aligned data handling, and a single-click revoke from your Google account. The documentation package is available for DPO review.
How to get started
The Class Add-Ons free plan includes one active scheduling task — enough to set up one recurring homework routine or reminder and see how the tool works with your classes. No payment card is required. Premium unlocks unlimited scheduling tasks for teachers managing multiple classes or routines.
