I hate to mention this so late in the game (finally got up the courage to tackle this thread today), but you all do know that all of the briefing and court orders are public record in the DC Superior Court records, right? Free to read by all, no speculation required. I couldn’t figure out how to link to the docket, so you are going to have to all look it up for yourselves. 
It will take you about 10 minutes to scroll to the end of the docket and click on the order.
Gist is, the court dismissed the breach of contract (settlement agreement) claims based on the Plaintiff’s failure to allege damages (emotional distress isn’t good enough in contract claims).
For the retaliation claims, the court sided with Sidwell because the only evidence Plaintiff offered were her own interpretations and opinions of what happened. Not facts. The court found that Sidwell’s explanations of why grades were or weren’t changed, or how Dayo was evaluated as to different schools as reasonable, and ultimately the Adetus’ dissatisfaction with Sidwell’s actions does not create a question of fact as to their propriety.
