Skill Group Code can be a Common Core code or just a number. If left blank, the sorting order is alphabetic based on the skill group name. However if there are skill group codes they control the sorting order, meaning that you can use them to set the order of the subgroups within their higher-level group or subject.
Skill Group Name is the actual text that is used for the group.
Detailed Description is for a more detailed description of the group.
Default Skill Type is not being used presently.
Default Scoring Rubric initially sets the rubric for all the lower level subgroups and skills. This is discussed under the Rubric topic. It makes sense to do this at the highest level possible.
Default Mastery Level Calculation determines how the calculation works for all of the skills within a standard.
