Roots is a part of Roots Education Association which functions as a Private Membership Association (specifically a Private Education Association). Private Membership Associations (PMAs) do business in the private sector only and require the customer to sign up for membership in the PMA in order to engage in all business transactions (similar to Costco, which is also a PMA). A PMA is simply a business structure, like an LLC or S Corp. Unlike an LLC or S Corp, a PMA does not have oversight by any governmental agency or licensing board.
Being a PMA gives Roots the freedom to be a school (a place of learning) without being a "school" (an institution beholden to the mandates of governmental oversight). As a PMA, the business of Roots, and the individuals working for the business, take responsibility for themselves and for the services provided. In addition, the members of the Roots PMA (i.e. parents and families) take responsibility for their choice to join the Roots PMA and engage in business with Roots. In this way, we are all called to act with integrity, honesty, authenticity, respect, and freedom.
