Course purchases, tiers, and student seats

Teachers purchase a 12-month course instance for a subject (course group) with chosen class and student-slot limits. Seat credits are no longer used.

Course groups

IT Support assigns curriculum to course groups (for example AP Precalculus). Content shared into Collaboration or the Public Library stays invisible to teachers who are not in that course group—even when Share ACL would otherwise show it.

Buying and activating

From the Courses page, activate a new course from a template (or from a closed course). Choose how many classes (1–7) and how many students per class (3–60). The quote uses volume discounts; checkout is stubbed until a payment processor is wired. One purchase creates one course instance.

Seats and classes

Inviting students no longer spends credits. Each class is capped at the students-per-class limit you purchased. Course Management shows occupancy like 37/40. Adding classes beyond your purchased max is blocked.

Expiry

The paid window lives on the course, not the teacher. Owners and co-teachers can change; when expires_at passes the course is force-closed. You can reopen the same course only while the window is still open; after that, buy a new instance.

After access lapses

Copies you own that carry a course group remain visible so you can view, manage sharing, or delete them—but you cannot edit, copy, print, or take practice tests until you rejoin the group (repurchase or become a co-teacher on an active class).

FAQ

Where do I see my purchases?

Account Settings lists your paid course instances with caps and expiry, along with profile, state, and time zone. See Account Settings: profile, location, and purchases.

Do I need credits to invite students?

No. Invites are limited by the per-class seat cap on that course.
