Merlin Coders
Introduction[edit]
Merlin Coders™ is a special program of Coder Merlin™ to bring recognition to dedicated and motivated students. Progress in the program requires demonstration of mastery in a topic which consists of one or more experiences.
As students demonstrate mastery of a topic they're awarded "wands" which are rendered as right-pointing chevrons. When a sufficient number of wands have been earned, students advance to the next level. After a series of levels have been earned students advance in the color of their sash.
Requirements for Demonstrating Mastery[edit]
Demonstration of mastery in each subject will occur through the successful completion of a Merlin Mission with a score of 80% or greater. In the case that the target score is not achieved, students may redo the Merlin Mission after no less than fourteen calendar days have elapsed.
Digital Badges[edit]
A digital badge is a visual symbol of achievement. Students can collect and share digital credentials that validate their skills and accomplishments, and send signals of success to networks that matter to them, such as Discord, Twitter, and Facebook.
