System Wide Enrolment Rules

These rules are maintained within the ENROLMENT/SYS-WIDE Rule Subgroup. Other Enrolment rules include message rules (sub groups MSG-GEN and MSG-SPEC) which are described in a separate document.

Sys-wide rules are applied to all units on enrolment. Currently there are two such rules, the System Wide Unit Rule and the System Wide Unit Quota Restriction rule (Unit Offering Quota Rule).

System Wide Unit Rule

This rule defines whether or not Unit Translation Set checking is enabled. If it is enabled, the rule further defines which units are evaluated in the checking process, in terms of:

• Passed units only or both passed and enrolled units, and
• Context course attempt only or all course attempts (institution-wide)

The application of this rule is also affected by the Translation Expansion Level rule, which is maintained in the rule sub-group SYSTEM SET-RULES. This rule defines the extent to which any rule translations will cascade.

RULE OPTIONS FOR SYSTEM WIDE UNIT RULE

Rule stem options	Rule Options	Usage
Context unit incompatible with	context course enrolled/failed units	unit cannot be enrolled if it has previously been attempted in, or is currently enrolled for, the context course attempt
	context course enrolled/passed units	unit cannot be enrolled if it has previously been passed in, or is currently enrolled for, the context course attempt
	institution wide enrolled/failed units	unit cannot be enrolled if it has previously been attempted, or is currently enrolled, in any of the student's course attempts
	institution wide enrolled/passed units	unit cannot be enrolled if it has previously been passed, or is currently enrolled, in any of the student's course attempts
Disable system wide unit rule		disables this rule only
Incompatible with	number previous (I/W) failures in context unit	unit cannot be enrolled if it has been failed the specified number of times previously
Level	{unit level,…} units require number (I/W) credit points	cannot enrol in the unit due to insufficient credit points having been achieved in the course
	{unit level,…} units require number (I/W) passed units from {unit,…}	cannot enrol in this unit due to insufficient units having been passed in the course
Must not exceed	number enrolled credit points in teaching period(s) { EASTER }	cannot enrol in this unit because credit points in teaching period(s) has been exceeded.
	number enrolled credit points in load period(s) { LOAD-CAL-1 }	cannot enrol in this unit because credit points in load period(s) has been exceeded.
Must have at least	number enrolled credit points in teaching period(s) { EASTER }	cannot enrol in this unit because the teaching period(s) must have at least the specified number of credit points.
	number enrolled credit points in load period(s) { LOAD-CAL-1 }	cannot enrol in this unit because the load period(s) must have at least the specified number of credit points.
Must have passed	number credit points in teaching period(s) { EASTER }	cannot enrol in this unit because must have passed a specified number of credit points in teaching period(s).
	number credit points in load period(s) { LOAD-CAL-1 }	cannot enrol in this unit because must have passed a specified number of credit points in load period(s).

Unit Offering Quota Rule

This rule specifies whether or not Callista's unit enrolment quota checking is enabled or disabled and whether or not this system wide setting can be overridden by individual unit quota rules. Unit quota rules are maintained via the Maintain Unit Version Rules form (CRSF2700). When enabled, quota rules are called either at the time a student unit attempt is added to a student or when a student's existing unit attempt is altered (in ENRF3000). The rules can also be checked by the Bulk Unit Rule Checking process (ENRJ0010).

The rules check the number of students already enrolled in a unit against the enrolment quota for the unit (specified in CRSF2500). The rule is failed if the current student unit attempt would cause the quota to be exceeded. The rules only apply to Unit Offering Options with quotas recorded for them.

The following table shows the four system wide rule options, the two unit quota rule options (plus null) and the effects of the interaction between these two types of rule.

Note:

· if no quota has been recorded for a unit offering option, these rules will not be tested for that unit during a student's enrolment.

· the unit quota rules shown in red text have no effect in that particular combination

System Wide Quota Rules	Unit Quota Rule Specified Against a Unit Offering Option	Overall Effect on Rule Checking of Combining the Two Types of Rule
Rule Option	Rule Option	Combined Effect
Quotas off - system wide - no override (Quota checking is disabled system wide, unit offering option rules are unable to override this)	null	No quota rule checking
	Quotas off (This option overrides the System Wide Quota Rule Quotas off - system wide - no override)	No quota rule checking
	Quotas on (This option overrides the System Wide Quota Rule 'Quotas off - system wide - override allowed')	No quota rule checking
Quotas off - system wide - override allowed (Quota checking is disabled system wide, unit offering option rules are able to override this)	null	No quota rule checking
	Quotas off	No quota rule checking
	Quotas on	Quota rule checking performed for specific unit offering options only
Quotas on - system wide - no override (Quota checking is enabled system wide, unit offering option rules are unable to override this)	null	Quota rule checking performed for all unit offering options with quotas
	Quotas off	Quota rule checking performed for all unit offering options with quotas
	Quotas on	Quota rule checking performed for all unit offering options with quotas
Quotas on - system wide - override allowed (Quota checking is enabled system wide, unit offering option rules are able to override this)	null	Quota rule checking performed for all unit offering options with quotas
	Quotas off	Quota rule checking is performed for unit offering options with quotas but not for specific unit offering options
	Quotas on	Quota rule checking performed for all unit offering options with quotas
