At Code.org, we are constantly striving to improve our computer science education offerings for teachers and students. As part of this ongoing effort, we occasionally retire older courses that no longer meet our quality standards or are outdated.
While we understand that these courses have been valuable resources for many educators, we believe that it's important to ensure that our materials meet the needs of modern learners.
Below you will find a list of our deprecated or non-supported courses and their recommended alternatives to help you continue providing high-quality computer science education to your students.
| Deprecated or non-supported Course | Alternative Course | Transition Materials |
| Course 1 | CS Fundamentals Course A | See this support article for more information about transitioning from Courses 1-4 to CS Fundamentals, which is actively supported and has an improved translation experience. |
| Course 2 | CS Fundamentals Course C or D (depending on the age of your students). | See this support article for more information about transitioning from Courses 1-4 to CS Fundamentals, which is actively supported and has an improved translation experience. |
| Course 3 | CS Fundamentals Course E or F (depending on the age of your students) | See this support article for more information about transitioning from Courses 1-4 to CS Fundamentals, which is actively supported and has an improved translation experience. |
| Course 4 | CS Fundamentals Course F for 5th graders or CSD if in middle school. | See this support article for more information about transitioning from Courses 1-4 to CS Fundamentals, which is actively supported and has an improved translation experience. |
| Computer Science in Algebra | Bootstrap: Algebra | Bootstrap offers a similar approach, updated content, and a wealth of resources to empower your students' computational thinking skills. |
| Accelerated Intro to Computer Science Course | Express Course | The Express course teaches the same concepts more effectively, is actively supported, and has full translation into over 30 languages. |
| Computer Science Principles (CSP) 17'18 and 18'19 | Computer Science Principles 25'26 | The 2025 course is the most up-to-date CSP course code.org offers. |
Along with deprecated courses, Code.org is beginning to remove older unsupported labs from the website. This means that any project created in this lab will be unavailable to run or view in code.org once the deprecated date is passed, we recommend taking a screenshot of your code if you want to keep the code.
| Lab | Course(s) used in | Deprecation Date |
| Calc Lab | CS in Algebra | July 2023 |
| Eval Lab | Cs in Algebra | July 2023 |
