Course Code Management

This guide is for school / organization administrators. It explains how to manage CodeCraft course codes in the school admin portal. How students use a course code to sign in is covered separately in Sign in with a Course Code. For an overview of CodeCraft’s education solution, see CodeCraft for Education.

Overview

Role	Responsibilities	Entry point
School admin / teacher	Sign in, manage the school, create and hand out course codes	School admin portal: codecraft-admin.seeed.cc/s/<your-school-id>
Student	Enter a course code to use CodeCraft — no account, no password	CodeCraft app: the “Class code” button on the home page

What is a course code?

A course code is a shareable code that students use to enter CodeCraft — no sign-up or login required, so they can start right away.

Session data is cleared on logout

When using CodeCraft with a course code, session content and output are cleared once the student logs out or the code expires. To keep their work (such as code and firmware), students should download it to their own computer.

Course codes are created and their seats are managed by the school / organization administrator. Each course code has:

• Seats — how many students can use the course code at the same time;
• Validity — the start time and end time;
• Remark — optional, to help you remember what the code is for.

Your school has a total seat pool (for example, 100). At any moment, the seats of all active course codes cannot exceed this pool. To expand the pool, contact your local distributor.

Accessing the school admin portal

1. In a browser, open your school admin link: https://codecraft-admin.seeed.cc/s/<your-school-id>
2. Type your access password, then click Enter.

You are now in the school management console. The top shows your school name, plus Service Status (showing “Active” and the service expiry date) and Seat Usage (showing used seats / total seats, for example 0 / 100).

Managing your school

Keep the access password safe

Anyone who has the access password can manage your school, so keep it tightly controlled and update it regularly.

1. In the console, find the School Profile card.
2. To rename the school, edit School Name. To change the password, enter a new one in Access Password (leave blank to keep unchanged) — leaving it blank keeps the current password. Then click Save. The new password is required the next time anyone signs in.

Creating a course code

1. In the console, go to the Course Code Management card. It shows current seat usage (active seats N / total seats 100) and the list of existing codes, with columns: Course Code, Status, Seats, Start, End, Remark, Actions.
2. Click New Course Code in the top-right corner.

3. In the dialog, fill in:

   • Seat Count — how many students can use the code at once, e.g. the number of students in one of your classes;
   • Start Time — when the code becomes usable;
   • End Time — when the code expires;
   • Remark — optional, e.g. the class or lesson name.

   Then click Save.

4. A new course code appearing in the list (for example FSBK83) means it was created successfully — copy it from there and hand it to your students. The Actions column lets you edit or delete the code.

Seat pool limit

At any moment, the seats of all active course codes cannot exceed your total seat pool. To let more students attend at the same time, expand the seat pool, or stagger the codes’ validity windows so they do not overlap.

10-minute buffer after expiry

After a course code’s end time, students’ previous session records are cleared once they are logged out. There is a 10-minute buffer during which the teacher can extend the end time; students cannot keep working during this window, but they are not logged out immediately.

FAQ

These messages are shown to students when they sign in with a course code:

Message	Meaning	What to do
Class code not found	The code is wrong, or it has been deleted	Check the code with your teacher; the teacher can verify it or create a new code in the admin portal
Class code not yet active, expired, or no seats left	Outside the validity window, or all seats are taken	Wait for the start time, or ask the teacher for a code with more seats
Class code expired	The code’s end time has passed	There is a 10-minute buffer for the teacher to extend the validity; after they extend it, click Retry to continue
Signed out due to inactivity	About 4 hours without activity; the system signs you out	Sign in again with the course code
