Clarion Ladies Academy

Clarion Ladies Academy is a finishing school in Connecticut, that Mr. Dare wanted Rachel to attend in The Last Olympian. She makes a deal with her father to go to this private school if he would let her leave the family holiday they were currently on in order to warn Percy that he was not the hero of the prophecy.

Rachel's Mom and the Academy
It is also said that Rachel's mom went to Clarion Ladies Academy some years before she met Rachel's father, Mr. Dare. Rachel tells Percy some of it in The Last Olympian inside Paul Blofis's car while staring out to the Atlantic Ocean while Percy is waiting for some time for the get-go to attack the Princess Andromeda offshore with Beckendorf.
