Random Assessment

The Random assessment type allows you to define a pool of assessments, with each student receiving a randomly selected assessment from that pool. Note that specific layout requirements apply.

Layout Requirements

• Simple Layout (1-panel): Multiple Random assessments can be added on the same page

• Complex Layout (multi-panel):

  • Cannot be added on the same page

  • Cannot be mixed with any other assessments

  • Warning will display when Publishing if mixed with other assessments

  • May not function as intended if layout requirements are violated

Duplication Prevention

Codio automatically prevents duplicate assessments at the assignment level by checking library assessment IDs for uniqueness. This ensures students won’t see the same assessment question multiple times within an assignment.

Requirements for duplication prevention:

• All questions in the assessment library must be unique

• All randomized assessments must be drawn from the same library

Note

If duplicate assessments are generated, the assessment library does not contain enough unique assessments to satisfy all random assessment queries in the assignment.

Creating a Random Assessment

1. On the General page, enter the name of your assessment that describes the test. This name is displayed in the teacher dashboard so the name should reflect the challenge and thereby be clear when reviewing.

2. On the Grading page, enter the amount of points to assign to the assessment. Enter the score for correctly answering the question they are assigned. You can choose any positive numeric value. If this is an ungraded assessment, enter zero (0).

• Use maximum score - Enables selection of the highest score from all attempts as the final assessment score.

3. On the Execution page, browse to an assessment library where you can set up filters define the range of assessments to randomly assign. You can work from any assessment library you have access to.

Filter Categories and Inputs

Bloom’s Taxonomy Level	Levels I-III Level I - Remembering Level II - Understanding Level III - Applying Levels IV-VI Level IV - Analyzing Level V - Evaluating Level VI - Creating
Assessment Type (auto-detected)	Code-Based Standard Code Test Advanced Code Test Parsons Puzzle Text-Based Multiple Choice Fill in the Blanks Free Text Autograde
Programming Language	Select the programming language for code-based assessments (e.g., Python, Java, C++, JavaScript)
Category (topic-level)	Broad subject area or topic category for filtering assessments (e.g., variables, functions, loops).
Content (sub-topic level)	Specific subtopic or concept within the category (e.g., modifying variables, creating functions, nesting for loops).
Learning Objective (SWBAT form)	Define what “Students Will Be Able To…” accomplish after completing the assessment Example: “Students will be able to implement binary search algorithms efficiently”

Updating Random Assessments

Modifying Assessment Parameters

To update, change, or review the assessments assigned to a random assessment:

1. Navigate to the Execution tab

2. Select the Update Search button

3. The assessment library field will open with your saved search parameters

   

Publishing Changes

After reviewing assessments, follow the appropriate publishing method based on your situation:

If ONLY random assessment changes were made:

• Students have not started: Publish normally

• Students have already started: Use the Sync button on the Edit tab (see Synchronizing Changes below)

If other assignment changes were also made:

• Publish normally first

• Then navigate to the Edit tab to sync if students have started

Synchronizing Changes from the Course

When random assessment changes are made (either by you or another organization member), synchronize them from the Edit tab in the course.

A Sync button appears on the Edit tab when changes are available to synchronize.

Warning

Students who have already started the assignment will not receive updates unless their assignment is reset. Resetting will cause them to start “as new” and all previous work will be lost.

Sync Options

When you press the Sync button, Codio will check if students have started and present appropriate options:

No students have started

The assignment will sync and publish to all students.

Students have started

You can choose to:

• Reset and publish: All students restart with new changes (previous work lost)

• Publish only: Only students who haven’t started receive the changes
