You can control how grades are shown at the school level, and also more granularly at the course level and the assessment level.
To determine your school-level settings, visit the Settings page and expand the "Report Cards" section. Here, you will find options for determining whether to show percentage scores (i.e. 95%), grading scale levels (i.e B+), both, or neither. There are separate settings for A) assessment results B) course results and C) standard results.
As a reminder, the left column configures this setting at the district level and the right column configures it at the school level of whichever school you're in.
School-level settings will apply to all courses, standards, and assessments unless you tell Schoolrunner otherwise, as shown below.
To specify how a particular course should report out grades, click the "edit" link on the course page and make your selection. This will affect how the final grade is displayed in the course grades table on the report card.
Note that in the interest of standardized results for standards-based grading, it's not possible to have different courses report out their standards results differently.
To set assessment results to display separately from your school-level settings, open the "Additional Options" on the assessment and make your selection. This will affect how the assessment results are displayed on the report card.
