Custom Scoring

Updated Mar 26, 2021

By default, each item uses "exact match" scoring, which means a student earns points for the item if they select all the correct answers (and no points are taken away for selecting wrong answers). You can, however, use scoring options to customize the scoring. 

Opening the Scoring Options

To change the scoring for an item:

  1. Edit the item's stem or responses. Refer to Editing an Item or Passage for more details on editing an item.
  2. In the item editor, click "More options" (located below the correct response answers):

Additional scoring options appear:

The options that display vary in "More options" vary, depending on the type of item. The options shown in the image above are available for item types such as "Multiple Choice - multiple response." 

Use the options to customize the scoring by allowing partial credit, deducting penalty points, specifying a minimum score, etc. Refer to the sections below for details.

Preventing an Item from Scoring

To prevent an item from being scored, click Unscored/Practice usage.

When Unscored/Practice usage is checked, the item is not scored. You may want to do this for practice items.

Allowing Students to Check Answers

When the option Check answer button is selected, a Check Answer button appears on the item in the online assessment. Students may click it to see whether their answers are right or wrong.

For example, the item shown below displays a Check Answer button. When students click it, they can see whether their answer choices are right or wrong and make changes if they want to.

If you select Check answer button, the Check answer attempts option controls the number of times the student may click the Check Answer button. Enter an integer into the Check answer attempts  box to allow multiple clicks on the Check Answer button. For example, if you enter 3, the student may click on the Check Answer button up to three times.

Allowing Partial Credit

The Scoring type option specifies how the item is scored. 

Each scoring option also uses the item's "Points" value, which is located in the "Set correct answer(s)" section of the item editor:

 

No Partial Credit

By default, the scoring for any item is "Exact match" scoring, which does not give partial credit: a student receives points only when they select all the correct answers. The number of points they receive is the value entered in the item "Points" box.

In the following example, the "Points" is set to 3. A student receives 3 points when they select ALL the correct answers:

The student receives no points unless they select all correct answers:

Partial match per response

With "Partial match per response" scoring, a student receives points for each correct response. The number of points they receive for each correct response is the value entered in the item's "Points" box.

In the following example, "Points" is set to 2. A student receives 2 points for each correct answer choice, which is 6 when they select them all:

If the student selects only two correct choices, they receive 4 points:

Partial match

With "Partial match" scoring, a student receives points for each correct response. The number of points they receive for each correct response is calculated as:

[value in the "Points" box] divided by [number of correct responses]

In the following example, the "Points" is set to 2. Each correct answer therefore gives 2/3 = .6667 points:

By default, decimal values are possible and no rounding occurs. However, when you choose "Partial match," a Rounding option appears. 

Choose "Round down" to round the points given down to the nearest whole number. 

For example, when "Points" is set to 2, one correct answer gives 2/3 points or .6667 points, and this rounds down to 0:

Turning off Auto Scoring

By default, most item types are scored automatically, and the option Enable auto scoring is checked:

Uncheck Enable auto scoring if you want to manually grade the item.

Important: If this item appears on an assessment, the assessment must have the option for "manual grading" checked. Refer to Grading Constructed Responses for details on manually grading items. 

Deducting Penalty Points

Penalty points are points that enCASE deducts from a student's score when they select an incorrect response. enCASE deducts points depending on the scoring type you are using and the value you enter into the Penalty point(s) box.

Penalty Points with "Exact match" Scoring

"Exact match" scoring (default) deducts all points when the student selects any incorrect response. There is no need to enter anything into Penalty points field.

In the following example, the item's "Points" value is 3 (which gives 3 points when all correct answers are selected). The student selects all three correct answers and one incorrect answer, making their score 3-3=0:

Penalty Points with "Partial Match per Response" Scoring

Using penalty points with "Partial match per response" scoring removes points for each incorrect answer selected. The number of points removed is equal to the value in Penalty points

In the following example:

  • the item's "Points" value is 2 (which gives 2 points for each correct answer)
  • the Penalty points is set to 2 (which removes 2 points for any incorrect answer)

The student selects two correct answers and one incorrect answer, making their score 2+2-2=2.

Penalty Points with "Partial match" Scoring

Using penalty points with "Partial match" scoring removes points for each incorrect answer selected. The number of points removed is calculated and is equal to:

[the value for Penalty points] divided by [the number of correct answers]

In the following example:

  • the item "Points" value is 3 (which gives 1 point for each correct answer)
  • the Penalty points is set to 3 (which removes 1 point for any incorrect answer)

The student selects two correct answers and one incorrect answer, making their score 1+1-1=1:

Setting a Minimum Score

By default, the lowest score a student can receive for an item is zero. To indicate a different lowest score possible (if the student selects ANY answer), enter a value into Minimum score if attempted.

For example, if you set the Minimum score if attempted 4, any answer (even a wrong one) gives the student four points:
