Yes, the Bartons have notified the district that they intend to sue. The district has six months to respond.
I hope they win. I hope the District uses this as an opportunity to change their system and train their teachers. I hope they have to pay for Alex's psychological counseling and a new school placement, such as a private situation with full support. I hope they respond to the filing by clearly agreeing to do these things, and then following through.
The district now has a fabulous opportunity to right some wrongs. Let's see if they do the right thing.
