Do I need to block out (indirect) time for testing, billing, or paperwork?

Generally, the answer to all of these questions is "no."  You do not need to block out time for testing, billing, paperwork, etc.

By default, the scheduling engine will attempt to give you large blocks of unscheduled time in every schedule that it generates.  The engine makes decisions about scheduling that result in the largest possible free blocks, which means that they might occur anywhere in your schedule.  It's generally best to let the schedule optimize this on its own, on your behalf.  This means omitting any special "Must Not" therapist availability entries for things like testing, billing, paperwork, etc.

If you've tried letting the scheduler handle it, and the it doesn't carve out sufficient time for your required activities, try scheduling again--but this time with your caseload Preference for "Maximize Productivity" set to 10.

If the gaps leftover between scheduled sessions do not suffice for your indirect needs, some alternative options exist:

• Have SLP Scheduler schedule a block of indirect time, wherever it best fits.  Just add a new student named "Indirect Time".
• Enter special "Must Not" therapist availability entries for things like testing, billing, paperwork, etc.  This makes the best sense if you require that one of these activities takes place during a specific day/time.  Just be sure to add them at days/times that don't place unnecessary constraints on the rest of your schedule.

If you have sufficient indirect time, but it's in too few blocks to be useful, please see:  Help! SLP Scheduler made me a schedule that's TOO efficient!
