In Texas, schools manage "activity funds" which consist of two types.
Campus Level Activity Fund promote general welfare of each school and the educational development and morale of all students. This would be for school-sponsored fundraisers, yearbook sales, picture sales, etc.
Student Activity Funds are the property of student organizations and are held by the school in a trustee capacity. (All the different clubs and organizations).
Parent and booster organization funds are NOT allowed to be accounted for in the school’s activity fund. They must be maintained independently by the organization owning them.
That being said, the principal does have many governance rights such as:
- Requirement that organization be properly/legally organized
- Approval rights for any information distributed throughout the school
- Approval rights for any activity held on school property
- Pre-approval of any fundraisers or activities
They may not exercise all these rights (and this isn't necessarily an all-inclusive list).
As far as fundraisers go, if the school "owns" it, the proceeds are deposited in the Activity fund. If fund belong to a PTA, PTO, Booster Club they cannot be deposited in the school accounts. Nor can the group use the school's sales tax exemption.

Booster clubs and parent-teacher organizations are separate legal entities from the school district and must maintain separate federal identification numbers and bank accounts. The University Interscholastic League (UIL) provides booster club guidelines on its website, as do national and/or parent-teacher organizations.
