Presbyterian Middle School (PMS for short) is the name of the school Massie Block attended prior to the beginning of The Clique series. During her time at PMS, Massie was a part of a clique called The Ahnnabees. The other clique in their grade was LMNOP, which Massie wanted to be a part of, but she couldn't be, as LMNOP already had an "M". Massie transfers from PMS to Octavian Country Day (OCD) at the end of Charmed and Dangerous: The Rise of the Pretty Committee.
