The PTO dilemma

No man ought to looke a geuen hors in the mouth. —John Heywood, 1546.
Our school district is blessed with active, involved parent/teacher organizations. These groups of dedicated parents raise funds and then use those funds to supplement district-purchased resources. And trust me, we as educators are grateful.
The problem comes when there is also a district goal to create equity among buildings, especially in regard to technology access. Disparities arise when different PTOs have differing abilities and desires to raise funds and when they have different priorities for how those funds are spent. Some buildings become quite technology-rich with the help of their parent organizations, while other buildings get by on what the district and building budget can provide.
Too often people view resources acquired through means other than district funds (grants, foundation gifts, PTO donation, fund raisers) as "nice extras" not as essential. If educational technology is viewed only as a "nice extra," I suspect many teachers and administrators will not regard it as a serious educational tool. If we genuinely believe technology can help students learn, why would we provide technology to some students, but not to all?
So when PTOs offer to purchase technology for a building, how should we respond? Are there some tech purchases that can be made but allow us to still maintain equity of access for all kids across the district? What if...
- All PTOs contribute to a single district-wide project or resource. Were all PTOs across a district to put their funds into a single pot which then could be used for district-wide purchases, equity would be increased. Let the PTO support e-book collections that are accessible to all kids. Let them contribute to an initiative that puts more student devices in all classrooms. Let them fund equipment for maker-spaces in all libraries. (In my experience, PTOs are not likely to accept this kind of plan.)
- PTOs fund technologies that the district is planning to purchase in the near future. If the district is planning to put voice amplification systems in all classrooms over a period of years, PTOs could contribute to doing this in individual buildings so kids get the benefit of the technology early. Possible, but not likely.
- PTOs fund staff grants for innovative uses of technology. I have a teacher who wants $600 to use Mindcraft stuff to investigate collaboration. Cool project, but there is no pot of district money to support such a project. What if PTOs were to fund well-articulated grants that had stated goals, metrics for measuring success, and means of diseminating the lessons learned from the funded projects. I think I like this one best.
Often times parents have a greater faith in the power of technology to help educate than do educators themselves so they encourage the use of PTO donations to acquire it. It's happened for the past 25 years in my experience and I doubt it will go away soon.
How do you handle PTO offers of technology purchases in ways that maintain equity of access?
