Merlin Coders

From Coder Merlin
Within these castle walls be forged Mavens of Computer Science ...
— Merlin, The Coder


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 that consists of one or more experiences.

As students demonstrate mastery of a topic, they're awarded "wands" that are rendered as right-pointing chevrons. When students earn a sufficient number of wands, they advance to the next level. After students earn a series of levels, they advance to a new sash color.

Requirements for Demonstrating Mastery[edit]

Demonstration of mastery in each subject occurs when a student successfully completes of a Merlin Mission with a score of 80% or greater. If that target score is not achieved, students may redo the Merlin Mission after no less than 14 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. They can send signals of success to networks that matter to them, such as Discord, Twitter, and Facebook.
