Accounts and Roles

The following are different types of accounts and roles you can have with CS First. Visit the different sections below to get more information on each.


The role of a CS First teacher is to set up a CS First class, recruit students, and in most cases administer the curriculum.

Create a CS First Teacher Account

If you would like to lead a CS First class, you will need to create a CS First account. Anyone (teachers, parents, after-school professionals, etc.) can create a teacher account. To create one, visit the Sign In page and click I'm a teacher on the right side of the screen.

Sign in to CS First using your new email address, and your existing class and teacher dashboards should appear. If that doesn't work, follow the standard Google Account Recovery process to reclaim access to your previous account.

The role of a co-teacher is to partner with and/or assist the lead CS First teacher. Responsibilities will vary and many classes will not have a co-teacher.

Co-teachers have the same access to class data as the lead CS First teacher. Co-teachers should only be added by the lead CS First teacher if they are certain they want this person to see all class information, including student progress.

Create a co-teacher account

A co-teacher is a CS First teacher account that has been invited to an existing teacher’s CS First class.

Coordinate with the lead teacher to join their class as a co-teacher by following the "Add a co-teacher" instructions below.

Add a co-teacher

To add a co-teacher to a CS First class

The lead teacher should

  1. Visit their Classes page.

  2. Click on the class.

  3. Click on Students on the left side of the page, and navigate to the "Co-teacher" section towards the bottom.

  4. Send the "teacher code" to the co-teacher.

The co-teacher should

  1. Log in to the CS First website as a teacher.

  2. On your Classes page, click Join a class.

  3. Enter the teacher code that was shared by the lead teacher.


Students are the participants in a class. Students will watch a series of CS First videos that instruct them how to create a project in Scratch. A student must use a CS First account in order for a teacher to track their progress and access their projects.

Create Student Accounts

The process for adding students to your class is also outlined on the People page of the class dashboard.

  1. Students visit the CS First website.

  2. Students click Sign in in the top right.

  3. Students click I’m a student.

  4. Students enter the class’s unique class code (found on the teacher’s Classes page) and click Next.

  5. Students confirm the class details and click Yes, join.

  6. Students select whether they need a new CS First username and password.

    • Usernames and passwords are anonymous and randomly generated by Scratch. Students can use these to log in to CS First and the Scratch website.

    • Students must confirm that they have written down their username and password somewhere that they won't lose it.

    • If the student has participated in a CS First class before, they can use their existing username and password to log in with your class code.

  7. Student accounts appear on the Students page of the class dashboard once students have logged in.

Delete student accounts

You can remove student accounts from the Students section on your class dashboard.

  1. Hover over a student’s row.

  2. Click the three vertical dots on the far right side of the row.

  3. Click Remove student from class.

If you remove an account by accident:

  1. Have the student sign in as a student, enter your unique class code as a new student and click Next.

  2. Have the student click Yes, join

  3. When asked if they need a CS First username and password, they should click No and enter their old account information, which will add them to your class again.

Student names have disappeared

To preserve student privacy, student names are stored only on your computer. They are never sent across the internet or stored on Google's servers.

Consequently, student names added using the "Add Name" feature on a class’s Students page are tied to the computer and browser you enter them on. If you sign in on a different computer or use a different browser, the names will not appear. Additionally, if your IT department has installed management software on your computer that periodically resets or restores it, names may be lost.

You can download and print a blank class roster and add student names there for a more permanent solution. To do so, visit, click on your activity, and toggle to the Materials tab. Many teachers also create their own spreadsheet to keep track of CS First student names, usernames, and passwords.
