If grades are not displaying in the student portal (as shown below), there are two places in Axiom that you can adjust the 'Student Portal Assignment Display' field. In order for grades to display in the portal, this field must be set to either *Assignments+Status+Scores* or *Assignments+Status+Scores+Grade Detail* (if you want to give access to the Grade Detail report).
You can adjust this field on the Permissions tab on the individual class. The dropdown for 'Student Portal Assignment Display' is located at the top of the page.
You can also adjust this field on the 'Review Class Configuration' query which can be found on the System homepage. This is especially useful if you want to batch update the 'Student Portal Assignment Display' field.
