Hi Doug.
I like the level of detail you've included. I'm not familiar with your technology but could still understand the requirements.
What I'm wondering about is where the pass/fail cutoff is. I found a rubric for wrining online courses that has 3 levels of proficiency -- essential (must be present/mastered for the project to be accepted), excellent, and exemplary. An exemplary course has all qualities in all 3 categories.
If you decided which skills were essential, then not demonstrating even one of those would mean that the student has to do more work and submit another report, even if some of the excellent or exemplary standards were met. That would be your pass level (sticker). If the student wanted a badge, he/she would have to fulfill the requirements at the next level. For example, to pass (earn a sticker) the writing standard might not be a critical factor. For a silver badge, the 150 word count & correct spelling might be the standard & for a gold, no mechanics errors.
The rubric could be set up checkist style. Then a student would see exactly what was missing in order to complete the requirements for a pass (sticker), or a silver or gold badge. Setting up a rubric this way means you don't have to figure out how many errors are acceptable at any level. The student becomes responsible for meeting the badge criteria kind of like in the boy scouts.
Hope this is helpful,
