- Minimum/Maximum Column
The minimum/maximum column is a type of calculated column that displays either the minimum or maximum grade for a selection of columns. For example, you can find the minimum score on all tests, but only show it in the Grade Center grid and not to your students on their My Grades pages.
Minimum: The percentage value for each column included in the calculation is compared up to four decimal places and the lowest value is displayed. The result displays up to two decimal places.
Maximum: The percentage value for each column included in the calculation is compared up to four decimal places and the highest value is displayed. The result displays up to two decimal places.
Three values: 8/10, 3/5, 2/2
Percentage equivalents: 80.0000%, 60.0000%, 100.0000%
Note: If two values are exactly the same for a minimum/maximum column, that is the value that appears in the Grade Center grid.
1. Go to the Control Panel >> Grade Center >> Full Grade Center >> Create Calculated Column >> Minimum/Maximum Column.
2. Type a Column Name This name becomes the column name in the Grade Center and on students’/participants' My Grades pages. If this name is too long to display clearly in the Grade Center, you can type a short, descriptive name in the Grade Center Name box.
Note: Only the first 14-15 characters typed in either name box appear in the column heading in the Grade Center grid. Point to the column heading to see its full name on the Grade Information Bar.

5. If grading periods exist, you can associate an average column with a grading period by making a selection in the Grading Period drop-down list. If no grading periods exist, the drop-down list does not appear. You can use grading periods to filter Grade Center data and create calculated columns.
