The alphabet soup of school parent volunteer groups (PTA, PTO, etc.) and their meanings can be pretty confusing, especially since the differences between the organizations can vary a lot!
This post will clear up any and all confusion you might have about school parent group names so you can get clear on what the name means and what resources you have available at your disposal.

What’s a PTO?
PTO (Parent Teacher Organization) is the umbrella name for all school parent groups (think “facial tissues”) and they’re independent/stand alone organizations that do not feed up into a larger organization.
PTOs generally have to learn on their own the best practices for running their group.
PTOs do not have any guidelines to follow outside of any local, state or federal laws.
PTOs are not required to charge membership dues.
And there’s no set offices or positions that must be filled each year.
There’s no list of PTOs, aside what you can find by searching for groups online.
Some PTOs are 501c3 organizations, but only if they have filed the appropriate paperwork with the IRS or if not based in the United States, with their country’s tax authority.
All school parent groups are PTOs (even if they’re a PTA).

What’s a PTA?
PTA (Parent Teacher Association) is the “brand name” for PTOs (think “Kleenex” or “Puffs”) and local units feed up into a national group through state PTAs and are organized into districts.
In addition to local, state and federal laws and regulations, PTAs have a set of guidelines to follow set forth by the National PTA.
PTAs are required to collect membership dues.
And they have certain positions that must be filled each year to be considered a PTA.
There are also various reports that need to be filed each year to stay in compliance with their State PTA or the National PTA.
State PTAs have different requirements for the reporting and compliance requirements.
Additionally, PTAs are usually 501c3 tax-exempt organizations that flows through from their affiliation with the State PTA.
All PTAs are PTOs.
If you’re considering leaving PTA to become a PTO, then you should definitely check out this post for a deeper explanation of the differences (and similarities, because there are a ton of them!).
The TLDR advice is to not leave PTA because I think it’s a waste of time, money and volunteer resources for an effort that does not benefit the students, staff or school.
My group is called something else…
Some school parent groups chose to have an entirely different name altogether.
And that doesn’t mean the group isn’t a PTO.
For example, some of the common names you might see for parent groups include:
Boosters
Home School Association (HSA)
Parent Association (PA)
Parent + Child (P+C)
Parent Council (PC)
Parent Child Council (PCC)
Parent Advisory Committee (PAC)
Parent Faculty Association or Parent and Family Association (PFA)
Parent Faculty Club (PFC)
Parent Group (PG)
Partners In Education or Parents for Inclusive Education (PIE)
Parents In Partnership or Partners in Parenting (PIP)
Parent-Initiated Treatment (PIT)
Parent(s) Organization (PO)
Parent Student Organization (PSO)
Parent Support Partner (PSP)
Parent Teacher Advisory Council (PTAC)
Parent Teacher Council (PTC)
Parent-Teacher-Counselor Organization or Parent Teachers and Community Members Organization (PTCO)
Parent Focused Treatment (PFT)
Parent Teacher League (PTL)
Parent Teacher Fellowship (PTF)
Parent Teacher Group (PTG)
Parent Teacher Partnership (PTP)
Parent Teacher Student Association (PTSA)
Parent Teacher Student Council (PTSC)
Parent Teacher Student Organization (PTSO)
Parent Teacher Teams (PTT)
Parent-Teacher Union (PTU)
Parent Volunteer Organization (PVO)
Student Council Association (SCA)
School Community Organization (SCO)
School Home Partnership (SHP)
Or another similar name!
While the specific function of the group may slightly differ, all of these school parent groups all have the same goal of enriching the school community for students and staff and are led by parent volunteers.
And so basically, no matter the exact name of the group, they all fall into the PTO category and should follow the guidance here on the site about how to organize and operate.
If you’re looking to get started as a PTO, reading this article is the first stop in the process.
PTA vs. PTO: Which group type is better?
The resources available to PTA groups is infinitely more than what’s available to PTOs, especially the network of volunteers that run from the local PTA units, up through the district level to the state PTA and then up to the National PTA.
PTOs have nothing similar to rely upon when issues arise, and they will arise at some point.
Principals or other administrators may infringe upon the independence of your group and if you are a PTO, then you don’t have other leaders to consult with on how best to respond. With a PTA structure, you have that built in network.
This is just one example of where having the support of the larger PTA organization can come to the rescue.
Watch this!
This video dives into the differences between PTO versus PTA parent groups.
Watch to learn the distinction and why that distinction ultimately matters!
Summing it all up
All PTAs are PTOs.
But not all PTOs are PTAs.
If your group name isn’t PTA, and you’re a school parent volunteer organization, you’re a PTO.
Got it?
Knowing the difference between the group names will help you understand what resources are available to you in your role as a parent group leader!
But at the end of the day, a name is just a name and all school parent groups are making a tremendous impact in their school community.
