Skill Recovery and Credit Repair Options

I currently developed an intervention plan for Skill Recovery and Credit Repair option using our teacher developed online courses in our eClass system.  eClass is our online portal used for communications between parent, teachers and students. The gist of the plan is that teachers will give students access core academic courses in the portal to attempt learning targets that they were not successful during the regular school day. I am hoping to roll it out in January. Does anyone have ideas on something similar at their school and any suggestions on Credit and Skill Recovery
