The logistics of the Listening Comprehension assessment

It is clear that all Group 2 teachers are spending quite some time figuring out how to best develop the students' listening skills in preparation for the new assessments.  The conversations in our Facebook group are a great starting point, and we encourage everyone to continue sharing thoughts, strategies, activities and successes. 
May 2020 will probably be upon us sooner than we realise, and besides helping the students prepare for the exams, we also need to think about the practical and technological implications of the discreet listening comprehension assessment.
Schools that offer a range of Group 2 courses will need to think carefully about the spaces in which the Listening Comprehension exams will take place.  I am aware of schools with as many as seven Group 2 courses, and several of these may have their final assessments on the same day.  This is challenge #1.
In addition, the quality of the exam space needs to be ensured.  Does everyone have the perfect sound system to play the recordings over one or two speakers that allow all the students to hear the sound files in the same way ? Or is your school equipped in such a way that every student will have their own listening device, which would allow you to drown out any outside noises ? Challenge #2.
For many of us this new assessment may have budgetary implications, even if it's just to ensure that we have adequate equipment to conduct this assessment.  Challenge #3.
One thing is for sure - the whole school will need to be notified when the listening comprehension exams take place, and probably the maintenance team most of all.  You may already be in this habit from the Individual Oral exams, but it could certainly be argued that a whole class listening to one single recording poses a greater challenge than one student listening to one teacher who sits just a meter or two away from them.  Challenge #4.
How are you preparing yourselves from a logistical point of view ? Please share.
