In-house exam timetables are generated in the same way, and from the same place as external exams. You can see how this is done here: Creating, printing and sharing candidate exam timetables
Can we exclude in-house exams from timetables?
No, it is not possible to exclude in-house exams from your timetables.
If they take place at different times of the year, you can try changing the date range to only include the exams ran at a certain time, which may exclude your in-house exams.
Can we print timetables for just our in-house exams?
Yes, remove all series from the Series box to only include In-house exams in your timetables.
Top Tip: You will need to have added students as in-house candidates to generate timetables with in-house exams: Set up your In-house exam candidates
