AAC use in the community

Hello,

I am new to the NAS forum/community and I work with a number of young people who use iPads as their voice . 

I am wondering if anyone has any experience with having to explain to a disability centre that using an AAC device is not the same as 'having screentime'? I am trying to help a centre understand that their no tablet policy means the young person has no access to express themselves when on site. 

Thank you

AK
