CRx Mode (Definition)

Use this page to learn how CRx mode works. 

CRx stands for "Credit Recovery". CRx is a feature that provides a unit Pre-Test for most courses. CRx mode allows students to "test out" of certain units by passing the Pre-test for the unit. If you have a student you believe already knows part of the material covered in a course, yet has gaps in their learning, CRx mode may provide the tool you need.

Not all Imagine Odysseyware courses are eligible to assign in CRx mode, for example, those courses for use with Advanced Placement (AP).

CRx mode allows you to assign the student a Pre-Test assignment (Alternate Test AT_icon.png) at the beginning of each unit in the course. You can set the CRx Pass Threshold for the school, student, or enrollment.


CRx mode works as described in the tables below based on whether or not the student achieves a score at or above the predetermined CRx Pass Threshold for a unit Pre-test.


Student achieves a score at or above the CRx Pass Threshold on the Pre-test in the first Unit
System automatically:
  • Changes the Pre-Test assignment status to "Graded".
  • Changes the status to "Skipped" for the remaining assignments in the unit.
Next steps for student:
  • Student can take the Pre-Test for the next unit in the course.
  • As long as the student achieves the CRx Pass Threshold for the Pre-Test of the next unit, the assignments in the unit are changed to "Skipped" and the next unit's Pre-Test is assigned.
Score results:
  • The score achieved on the Pre-Test becomes the unit score
Student does not achieve a score at or above the CRx Pass Threshold on the Pre-test
System automatically:
  • Assigns those assignments related to all missed questions on that unit Pre-Test with the first of these assignments' status changed to "Assigned" and for the remaining assignments, changes their status to "Not Started".
  • For those assignments related to questions answered correctly on the Pre-Test, their status is changed to "Skipped".
  • Recalculates the Due date based on the enrollment term.
Next steps for student:
  • The status of the Pre-test is automatically set to "Skipped".
  • The Lesson Pass Threshold is then used for all lessons in the unit and not the CRx Pass Threshold.
  • Quizzes and the other post-tests in the unit are treated as they are in any other course; students may have only one opportunity to complete a quiz or test based on the set number of attempts and the score they achieve is the recorded score.
  • Questions associated to lessons not assigned are skipped on the related quiz.
  • Review type assignments (only those with the RV icon RV_icon.png) are set to "Not Started" status when the score on the PreTest assignment does not meet the CRx Pass Threshold (grading) score. When the preceding assignment is completed, the Review type assignment is then set to "Assigned" status so that Students have the opportunity to review all the material for the unit.
Score results:
  • The score for the Pre-Test is discarded and the unit score is the cumulative of all lessons, quizzes and the post-test for
    the unit.
  • If the assignment has any other status, the Pre-Test score is then factored into the overall grade for the unit.
