Total testing time would depend on the test(s) being performed and the student.
in my opinion multiple tests should not be administered in one sitting -- it may be overtiring for the student and produce erroneous results.
My son has been tested extensively by the sd and privately. All testing was done over several days.
When a student is referred for the initial evaluation, there is a 60 day timeline within which the sd must complete the evaluations. I haven't located a reg that depicts a time requirement for reevaluations.
Sds perform a huge number of evaluations yearly. They have some type of tracking system for scheduling (similar to a doctor's appointment schedule). They should be able to provide the dates your child is scheduled (if they have been scheduled).
