Walton Penner, a stay-at-home parent, supports the “school choice” education reform movement, seeking to shift resources from public education to privately-funded options or impose market economic frameworks on public education. One summary biography of her explains that the Walton Family Foundation, of which she is a board member, “believes that the best way to achieve continuous and sustainable improvements in K–12 schools is to create competition among schools by empowering parents to choose among them.”

Her previous jobs have included:

  • Program Officer for Education, Walton Family Foundation
  • Research Analyst for an evaluation of the Michigan Mathematics and Science Centers

Political giving

Walton Penner is an active donor to politicians at both the federal and state level, and has used her wealth to promote political causes in states she doesn’t live in.

Federal contributions

Walton Penner has been an active donor to politicians running for federal office. She gave the most during the 2004 election cycle, when she gave more than $100,000 to politicians—97% to Republican candidates.

Examples of state-level contributions

  • Louisiana: In October 2011, Walton Penner and her husband Greg Penner each donated $5,000 to Kira Orange Jones, a candidate for the Louisiana State Board of Elementary and Secondary Education (BESE). Orange Jones, the Teach for America head in New Orleans who was elected to the BESE in this fall’s election, is said to have “[run] as the embodiment of post-Katrina reform efforts in New Orleans”—reform efforts that have been focused on charter schools and school privatization. Greg Penner is on the board of Teach for America.
  • Wisconsin: Walton Penner has funded Republican candidates for state office in Wisconsin, a state she doesn’t live in. As the Wisconsin Center for Investigative Journalism reported in September 2011, Carrie Walton Penner was the second-largest individual contributor to winning state legislative candidates in the 2010 elections that put Republicans in control of the state government; six of the top ten donors were members of the Walton family. Under the first budget passed by Gov. Scott Walker and the Republican-majority legislature, funding for public schools was cut by $800 million over two years, while funding for programs that funnel public money to private schools increased by $17 million over two years.
