Here we will explain how a rubric is scored.

First we must understand a bit on how rubrics are put together.

The score is the percentage of the total possible points of the given rubric.

Rubric

Rubrics are broken up into categories, each category is weighted, Category A may be worth 10% of the total possible points and Category B might be worth 90% of the total possible points.

Judging Categories

Categories have assessments (questions) that are scored by judges, the categories total weight (max points) is the sum of the max weight (max point) per assessment. Each assessment has a point range which can be assigned to it. 

Assessments (questions)

Each assessment has a score type/range. The max value of the score type is the default weight of the assessment. This means a yes no assessment is only worth 1 point for this category.

Range Types

  • Yes/No (Yes = 1, No = 0)
  • 1 - 3
  • 1 - 5
  • 0 - 3
  • 0 - 5
  • etc.

Assessment Weight

If you need the assessment to be worth more you can assign a weight to the assessment. If you want a Yes/No type to be worth 10 points in this category you would assign a weight of 10.

Calculating Score

Category Score

First we calculate the score for each category in your rubric. This is done by calculating the max score possible for the category. Which is the sum of each assessments max points or weight if set.

Then we calculate the percentage of the points earned.

Score

We multiple each categories score percentage by the weight of it's category and sum the total.
