Welcome to The Rubric Tool!

This is a tool for adjusting grade boundaries in a rubric.

Before you proceed, use the sample data to familiarise yourself with the tool. To load it, press the “Load sample data” button, and at any time, press it again to start afresh.
THIS TOOL IS TOUCH-SCREEN FRIENDLY.
Panel A: Course details
(* = mandatory)
Instructor(s) *
Note: It is mandatory to fill all the fields in Panel A if you want them printed on the chart.
Panel B: Input data
There are two ways you can input data: either paste data from a spreadsheet or upload your file. For structured data, include a column with the header Marks. You may also include Name, Programme, and ENR NO. For quick testing, you may also paste or upload marks only as a single-column TSV/CSV list, with or without a header.
Note: The data loaded with either method is shown in Panel G below.
OR
Note: To upload a new file, click Choose file. This action will overwrite the previous file.
Panel C: A and NP cutoffs
Min marks for PASS grade
Min marks in this data: –
adjustable (enter value or use arrows)
Min marks for A grade
Max marks in this data: –
adjustable (enter value or use arrows)

If you want a visual tool to set the NP and A cutoff values (or percentiles), then use the Quartiles tab in this link with the same data: davtools.bhargavadhvaryu.net

Notes
  1. Enter A and NP cutoff values (red cells). You may use the min and max marks of the data and/or the percentile values in Panels E and G.
  2. By default, bands from A- to D are equally distributed (rounded) based on your cutoffs. Since the bands use rounded values, the interval widths may be slightly unequal.
  3. See the default frequency distribution, i.e., based on the equal or nearly equal class intervals. If the distribution is as desired, then no adjustments may be needed. Further adjustments can be made to the class intervals for A-D to shape the distribution as desired. In addition to the distribution, keep an eye on the mean marks and mean GPA displayed in the graph.
  4. At any point, if things get messy, press the Reset "equal-ish" intervals.
