Submission rules may be entered to ensure students select subjects in line with curriculum guidelines.
1. Co-requisite rule
Some subjects may require a second subject to also be selected. This is entered as a 'co-req' course rule.
Go to Lines > Elective data > Courses, and next to the subject that requires a second subject to also be selected, enter the CourseCode of the subject they must also select.
Go to Lines > Elective data > Courses, and next to the subject that requires a second subject to also be selected, enter the CourseCode of the subject they must also select.
Example: If a student selects Maths - Specialist, they must also select Maths - General. 11MAG has been entered as the co-requisite course.
A Student will not be able to select Maths - Specialist without also selecting Maths - General.
2. Units rules
Sometimes there may be rules around selecting a minimum or maximum of a type of subject. These are known in Edval as 'at least' and 'no more than' rules:
a) ‘at least’ rule
The 'at least' rule requires that students have 'at least' the specified number of units of a subject category as part of their program.
Some examples:
- Year 11 students must select an English subject as part of their program
- Year 10 students may be required to select an English, a Maths, a Science and a Humanities subject as part of their program
- Year 9 students may be required to select both an Arts and a Technology type subject.
Some examples:
- Year 11 students must select an English subject as part of their program
- Year 10 students may be required to select an English, a Maths, a Science and a Humanities subject as part of their program
- Year 9 students may be required to select both an Arts and a Technology type subject.
b) ‘no more than’ rule
The 'no more than' rule stops students from selecting more than the specified number of units of a subject category.
For example:
- Year 11 students may not be able to select more than two Science type subjects as part of their program
- Year 9 students may not be allowed to have more than one Arts or one Technology subject.
For example:
- Year 11 students may not be able to select more than two Science type subjects as part of their program
- Year 9 students may not be allowed to have more than one Arts or one Technology subject.
Step 1: Categorise courses
In the Lines > Elective data > Courses > Rules field, assign a letter (A-Z), a digit (0-9) or a special character from the following !@#$%^&*() _+ to categorise, or group, subjects of a type that need a submission rule associated.
For example, all English type subjects might be given the letter E, Science type subjects might be given the letter S and Mathematics type subjects might be given the special character $.
Step 2: Enter a rule
Go to the Action bar on the right and select 'Rules and Constraints'. Enter the required 'at least' or 'no more than' rules.
Example:
- Students must select 2 units of an English subject. All English courses have been assigned the letter E in the Courses Rules field, then the 'at least' rule added. at least - 2 Units - Group E
- Students must not select more than two Science courses ( or 4 units). All Science type courses have been assigned the letter S in the Courses Rules field, then the 'no more than' rule added. no more than - 4 Units - Group S
- Students must select 2 units of an English subject. All English courses have been assigned the letter E in the Courses Rules field, then the 'at least' rule added. at least - 2 Units - Group E
- Students must not select more than two Science courses ( or 4 units). All Science type courses have been assigned the letter S in the Courses Rules field, then the 'no more than' rule added. no more than - 4 Units - Group S
A Student will not be able to select 6 units of Science type subjects.

Both the Coreq rule and Units rule are used during online Choice subject selections and line generation. Any violation of these rules are flagged in the Elective data > Students screen.
3. Prerequisite rules
A prerequisite rule determines who is automatically eligible for a course. Eligible students are able to select the course during online Choice subject selection.
Go to Lines > Elective data > Courses, under the Prereq field enter the requirements for a course. Multiple combinations of requirements, including attendance or exam results, can be added.
Important: Prereq rules are only used during online Choice subject selection process and are not considered during line generation. Any violation of prereq rules are not flagged in Elective data > Students screen. The prereq rules do not apply if student's subject choices are manually imported or entered into the etz file.
