Clash Prevention proactively blocks students from selecting activities that overlap with their existing team commitments or other activities they are already scheduled onto. When enabled, conflicting activities appear disabled in the Portal with a clear explanation, preventing selection errors before they occur.
​

This feature saves significant administrative time by eliminating the need to manually identify and resolve scheduling conflicts after Activity Selection closes.

Eliminates hours of manual work identifying and resolving scheduling conflicts after selections close. Schools no longer need to move students between activities or contact families about double bookings.
​

Families receive immediate, clear feedback about scheduling conflicts upfront, rather than discovering issues after submitting their selections. This creates a fairer and more transparent selection process.
​

Ensures students are only enrolled in activities they can actually attend, reducing no-shows and improving participation rates across your extracurricular programme.
​

Particularly valuable for schools with preferential selection systems, rolling enrolment programmes (like music tuition), or extensive co-curricular offerings where manual conflict checking becomes impractical.
​
​

Important: Clash Prevention detects conflicts between a student's existing Current Team or Session assignments and the Activity they are about to select. If a student is already assigned to a team with Sessions that overlap the new activity's Sessions, the selection will be blocked. However, two Activities selected in the same cart or preferenced together will not trigger a clash against each other - only pre-existing commitments are checked.

Clash Prevention only checks against teams with Current status. Teams marked as Planned won't trigger conflict detection. This means you should consider moving teams from Planned to Current status before opening Activity Selection.
​

When Clash Prevention is enabled, conflicting activities appear differently in the Portal.
​

For multi-option activities: A conflict warning appears, and the specific conflicting option is disabled.

For single-option activities: The entire activity shows as unavailable with the message: "You are already enrolled in an activity that conflicts with this selection"
​

Students can still view the Activity details and Session Calendar, but cannot select it until the conflict is resolved.
​​

Prerequisites:

Step-by-step setup:

The feature will now actively prevent students from selecting this activity if they have scheduling conflicts with their existing commitments.
​
​

The Clash Calendar defines the date range used for conflict detection. Clipboard only checks for Session overlaps within this configured period.

Best practice: Set your Clash Calendar to cover the entire term or programme period for which you're running Activity Selection. This ensures conflicts are detected across the full duration of activities.
​

Situation: Sam is on Basketball Team A, which has Sessions every Monday 3-4pm. Sam tries to select Chess Club, which also runs Monday 3-4pm.

Result: Chess Club appears disabled in the Portal with an error message explaining the conflict. Sam cannot select Chess Club unless they're removed from Basketball Team A.

Situation: Jordan is not currently placed in any teams for Basketball or Drama Club. Jordan tries to select both "Basketball" (Monday 3pm) and "Drama Club" (Monday 3pm) in the same selection round.
​Result: No clash is detected. Clash Prevention checks against existing team assignments, not against other items in the same cart or preference list. Jordan can select both activities.

​Tip: If Jordan is later placed in the Basketball team, a clash would then be detected if they tried to select another Monday 3pm activity.
​

Situation: Alex is on Football Team A with 'Planned' status, which has Sessions Wednesday 3-4pm. Alex tries to select Drama Club, also Wednesday 3-4pm.

Result: No clash is detected because the team status is Planned, not Current or Confirmed.

Impact: Always move teams from Planned to Current status before opening Activity Selection to ensure proper conflict detection.
​
​

Solution: Check that you've toggled on Prevent students and guardians from selecting activities that conflict with the linked Team's schedule. Also, verify that:

Solution: Clash Prevention only detects conflicts between a student's existing team or session assignments and a new selection. If the student isn't already assigned to a Linked team with overlapping sessions, no clash will be detected. Check that:

Solution: Review the student's existing team memberships and already-selected activities. The system may be detecting legitimate conflicts you weren't aware of. Check:

If the conflict is incorrect, you may need to adjust Session times or temporarily disable Clash Prevention for that activity.
​
​

Ensure team assignments are up to date: Since Clash Prevention checks against existing team assignments, make sure students are placed in their Current Teams before opening Activity Selection. This gives the system accurate data to detect genuine scheduling conflicts.

Move teams to Current status early: Since Planned teams don't trigger conflict detection, update team statuses before opening Activity Selection to ensure accurate clash prevention.

Configure Clash Calendars carefully: Set date ranges that cover the entire period when activities run. A Clash Calendar that's too narrow may miss legitimate conflicts.

Test before opening selections: Create test student accounts and verify that Clash Prevention works as expected before opening Activity Selection to your school community.

Communicate clearly with families: Let parents and guardians know that clash prevention is enabled, so they understand why certain activities appear disabled. Consider adding a note in your Activity Selection communications.

Use alongside preferential selection: Clash Prevention works particularly well with preferential Activity Selection systems, ensuring students only list preferences they can actually fulfil.
