Analysing Grade Distributions of my Assessments and Strands

What is Arbor’s Grade Distribution tool?

The grade distribution tool can be found in the assessment module's Analysis pages.

The grade distribution tool lets you view the distribution of student grades for each assessment. First displaying a summary for each assessment period, you can then dig down into each strand of an assessment (for a summative assessment with strands). You can then perform actions for groups of students you have identified, such as emailing or adding to an intervention etc.

You can view grade distributions for Summative, Ad Hoc and Standardised Assessments. just go to Students > Assessments > Summative Tracking > Analysis > Grade Distribution, then select your assessment using the filters at the top of the page.

 

Setting the Filters

The filters at the top of the page allow you to choose which students and assessments to display. You can select multiple assessments to compare grade distributions.

Click Save Changes to view the distributions.

Using the filters you can choose to display student names in the table view so you can easily see which student is in each group.

In the slide over, you will see a list of the students achieving this grade. Select one or more students using the checkbox column to the left of the table and perform a number of actions as shown in the screenshot below.

1 Chart and content

By default, the chart will display the distribution of grades for your selected assessment by assessment period, as shown in the screenshot above.

If the summative assessment has strands, you can click on an assessment period in the chart (Indicated with the orange 3 in the screenshot above) and drill down to see the grade distribution by strand in a given assessment period. The screenshot below shows the grade distribution by strand for the ‘Spring 2’ assessment period.

2 Chart title

This field will always display which assessment periods have been included in a chart. This is especially useful if you want to see the grade distribution by strand and need a reminder of which assessment period you are viewing.

3 Assessment periods

Each bar in the chart represents the grades for a given assessment period. For summative assessments with strands, you can click the bar to see the grade distribution by strand.

 

4 Grade Key

This additional filter layer enables you to focus on a particular grade/mark when viewing a grade distribution chart. It is most useful when analysing a summative assessment that contains a wide range of grades/marks. Just click the grade to analyse the chart further.
