When using a hierarchical standards bank, parent standards are the top-level standard which have one or more directly-assessed child standards.  More information on the structure of standards in the bank can be found here.
The title of a parent standard should be relatively short to ensure reports (e..g proficiency transcripts) can be appropriately compact.  Use the description for the full text of a standard.
Weight is optional; leave it blank for the weight to inherit from the child standards.  To make all parent standards equal in weight, give each a weight of 1.
When building your standards bank, always create parent standards first since child standards are required to belong to a parent standard.
The standard type and content area of child standards are inherited from the parent standard.
Standards can belong to more than one standards bank.  When adding a child standard to a bank, ensure that the parent standard also belongs to the bank; a parent standard can belong to a bank even if not all of it's children do.
