Throughout the Official Mark Calculator, courses that are deemed equivalent to other course challenges are used in various contexts.

To identify Course Challenge Equivalencies that should be considered, the calculator first identifies a list of courses the student has successfully challenged (along with the school years in which they challenged the course). This list of challenged courses is built by iterating through the Course Enrolment and Evaluated Mark for the student.

For each Course Enrolment, if the Course Enrolment includes an approved passing mark and is associated to a Section with a Primary Delivery Method of Course Challenge (CHA), the course code is identified as a course that the student successfully challenged in the school year of the associated section.

• Challenged Course . Course Code = Course Enrolment . Course Code (Course Enrolment)
• Challenged Course . School Year = Course Enrolment . Section . Section School Year

For each Evaluated Mark, if the Evaluated Mark includes an approved passing mark and has an Evaluated Mark Evaluation Method of Course Challenge (CHA), the course code is identified as a course that the student successfully challenged in the school year on the Evaluated Mark.

• Challenged Course . Course Code = Evaluated Mark . Evaluated Mark Course Code
• Challenged Course . School Year = Evaluated Mark . Evaluated Mark School Year

Once all the challenged courses have been identified, the calculator identifies a list of courses that are deemed course challenge equivalents to the challenged courses. This is done by iterating through the list of challenged courses. For each school year in which the student challenged a course, the calculator identifies the courses that are deemed course challenge equivalents to the course in the year in which the student completed the challenge. This is done by finding Course Relationships that meet the following criteria:

• Course Code is the same as the Course Code of the course the student challenged.
• Relationship Type (Course) is for a Course Challenge Equivalency (CHA)
• First School Year (Course Relationship) is the same as or earlier that the School Year in which the student challenged the course.
• Last School Year (Course Relationship) (if provided) is the same as or later than the School Year in which the student challenged the course.

For each Course Relationship found, each of the Related Courses is added to a list of potentially equivalent courses.

• Potential CHA Equivalent . Challenged Course Code = Challenged Course . Course Code
• Potential CHA Equivalent . School Year = Challenged Course . School Year
• Potential CHA Equivalent . Equivalent Course Code = Course Relationships . Related Courses . Course Code

By matching the list of { Potential CHA Equivalent . Challenged Course Code } against the list of { Passed Course . Course Code }, the potentially course challenge equivalent courses will be considered a valid course challenge equivalent course if the list of { Passed Course . School Years } for the challenged course code is the same as the list of { Potential CHA Equivalent . School Years } for the same course code.

Each potentially equivalent course that passes this validation is then added to the final list of course challenge equivalent courses:

• CHA Equivalent Course . Challenged Course Code = Potential CHA Equivalent . Challenged Course Code
• CHA Equivalent Course . Equivalent Course Code = Potential CHA Equivalent . Equivalent Course Code

When needed, the official mark calculator can then reference this list of course challenge equivalent courses.

Consider the following set of course enrolments:

Consider the following set of evaluated marks:

The list of challenged courses would include:

Consider the following Course Relationships for ABC1111:

The list of potentially equivalent CHA courses would include:

Validating the school years compares the list of school years for the passed courses against the list of school years for the potentially equivalent courses:

Therefore, the validated list of equivalent CHA courses includes:
