Clash Detector

Use the Run Clash Detector option in the Timetable Manager module to check for lesson clashes on your selected timetable. Clashes maybe imported from your existing timetable or can occur while you are adding lessons or correcting errors in the timetable. You can check for lesson clashes on student, teacher and room timetables with this tool. You can then access timetables directly from the option if you need to edit, delete or hide lessons in timetables.

Clashes on timetables do not stop the module functioning but can cause confusion to students and teaching staff if they are not amended in the timetable.

To use the Clash Detector, follow the steps below:

1. Open the Timetable Manager module and select the timetable tab that you want to work with:
   
2. Select Run Clash Detector in the right hand options menu:
   
3. Select a tab to check for clashes on either a Student, Teacher or Room timetables.
4. Select a student year group, teacher or classroom from the list displayed (the option available depends on the tab that you are working in).
5. Click Locate Clashes.
   All students/teachers/rooms with timetabled lessons are displayed. An icon is displayed next to each listing, this indicates whether lesson clashes are present or not:
   
   • indicates that there are no lesson clashes.
   • indicates that lesson clashes are present. The total number of clashes for each listing is shown in the Total column. The period numbers with clashes is shown in the Clashing Periods column.
   These icons are useful for checking lesson clashes on student timetables where timetables are listed for the whole student year group. Use the icons to quickly run through the records and identify those which have lesson clashes.
6. Click to view the clashes in a selected timetable. The edit timetable window is displayed:
   
7. Scroll through the timetable to locate lesson clashes.
8. Either:
   
   • Click on a lesson to edit it. Select a different teaching set, teacher or room for the lesson. See Edit a Lesson to guide you through this procedure. Move individual students into different teaching sets if you have multiple clashes on one student timetable; edit teaching sets in the Teaching Manager module.
     or
   • Click on a lesson to delete it. This removes the lesson from all timetables. The delete lesson function is setup in the Configuration tab and may not be available. Go to the Manage Lesson Schedule option if the delete icon is not available and you still want to delete a lesson.
     or
   • Click on a lesson to hide it. The lesson is only hidden in the timetable selected. Hiding a lesson does not change the lesson anywhere else in the module and the lesson is still listed as a clash in the Clash Detector screen. This is useful if you have one student in a teaching set displaying a clash on their timetable and you do not want change their teaching set. This may occur if a student has extra learning support tutorials.
9. Click Close Window to go back to the Clash Detector screen. Click Locate Clashes again if you have edited or deleted lessons, the list is updated.

Remember that any changes to timetables does not just change your selected timetable but all timetables which include this lesson. For example, if you select to delete a lesson this lesson is removed across the module.
