The Software Engineering Program Junior (SEPjr) is a high-quality computer science program for kindergarten through fifth-grade students that balances rigorous and meaningful direct instruction with open-ended creative computing.

Teachers and students engage in foundational computer science concepts through teacher-directed lessons and the application of computer science, including through open-ended creative computing platforms such as Scratch, robotics and maker education. The SEPjr curriculum is aligned with the the CS4All Blueprint concepts and practices, with an emphasis on Explorer and Creator perspectives.
