Google Classroom Guide 2026: How to Log In, Join a Class, and Turn In Assignments

Google Classroom works the same way it always has: go to classroom.google.com, sign in with a Google account, join your class with a short code from your teacher, and submit assignments from the Classwork tab. What’s changed for the 2026-27 school year isn’t the basics — it’s a wave of Gemini AI features Google has been folding into both the student and teacher sides of the platform since early 2026. Here’s how to use the core features, and what the new AI additions actually do.

What’s new in Google Classroom this school year?

The biggest change for 2026-27 is Gemini showing up directly inside Classroom, for both students and teachers. On the student side, Google has been rolling out a dedicated Gemini tab that acts as a study companion tied to a class’s own posted materials — generating flashcards, practice quizzes, and study guides, and answering questions in a Socratic, guided-tutoring style rather than just handing over answers. On the teacher side, a separate “Classroom app in Gemini” finished rolling out by June 18, 2026, according to Google’s Workspace Updates blog, letting teachers draft assignments and class announcements and get quick summaries of who has and hasn’t turned in work, pulled straight from their own Classroom data. Google says access to both is on by default but controlled by school and district admins, and that Workspace for Education data isn’t used to train its underlying AI models.

How do I sign in to Google Classroom?

You sign in at classroom.google.com using a Google account — either a school-issued Workspace for Education account or a personal Google account, depending on what your class requires. After entering your credentials, you’ll see a welcome screen; if it’s your first time using Classroom with that account, you’ll be asked to choose “I’m a Student” or “I’m a Teacher,” which determines what the interface shows you from that point on. The Android and iOS Classroom apps use the same sign-in.

How do I join a class with a class code?

Get a class code from your teacher (it’s 6 to 8 letters and numbers, no spaces or symbols), then click “Join class” on the Classroom home screen and enter it. On the web, “Join class” appears as a button on your Classroom homepage after you sign in; in the Android or iOS app, the same option is under the profile-icon menu. You only need to do this once per account — once you’ve joined a class on any device, it shows up automatically everywhere else you sign into that same Google account.

How does turning in an assignment actually work?

Open the class, go to Classwork, click the assignment, then use “Add or create” to attach your work before hitting “Turn in.” You can attach an existing file from Google Drive, paste a link, upload a file from your device, or create a brand-new Google Doc, Slide, Sheet, or Drawing directly from the assignment screen. Once everything’s attached, click “Turn in” and confirm — the assignment’s status then switches to “Turned in.” If you submit or mark it done after the due date, Classroom flags it as late. Before the deadline, you can also click “Unsubmit” to pull work back, make changes, and resubmit.

What can students actually do with the new Gemini tab?

The Gemini tab turns a class’s own posted materials into interactive study tools instead of generic web answers. According to Google’s product announcements, students with access can select course content and ask Gemini to build flashcards or a practice quiz tailored to that specific class, work through material in a guided question-and-answer format, and pull together a study guide or notebook ahead of a test — all grounded in what their own teacher actually assigned, rather than an open-ended chatbot session.

What can teachers do with the Classroom app in Gemini?

Teachers can use Gemini, with Classroom connected as context, to draft assignments and posts, build timelines for a unit, and get a quick read on which students have submitted work and who might be falling behind. Google’s Workspace Updates blog describes teachers using it to update assignment details across multiple classes at once, put together seating charts, and locate older assignments without digging through each class individually — essentially using Classroom’s own records as the source material for Gemini’s suggestions.

Is student data used to train Google’s AI models?

Google states that Workspace for Education data, including anything used inside Gemini through Classroom, is not used to train its AI models. Access to Gemini-in-Classroom features is controlled at the admin level, meaning individual schools and districts decide whether the Gemini tab and Classroom app are turned on for their accounts, and Google has continued expanding exactly who gets access: starting August 10, 2026, the company opened Gemini in Classroom to K-12 students of all ages who already had Gemini access approved by their school, following earlier limits tied to age and account type.

The bottom line

For day-to-day use, Google Classroom still boils down to three steps: sign in, join with a code, and turn in work through Classwork. The Gemini additions layered on through 2026 — a student study tab, a teacher-facing Classroom app inside Gemini, and steadily expanding age access — are Google’s biggest push yet to make that AI assistance feel built into the classroom rather than bolted on, and Google has continued adding to the feature set into September 2026, so it’s worth expecting more changes as the school year goes on.
