“ACT’s commitment to helping people be successful in their education and careers is why I joined the organization. As a first-generation college student from a small rural area I know firsthand the life-changing impact education can have on an individual, a family and a community. I’m committed to providing research-based products and services that provide meaningful and reliable information, and supporting evidence-based outcomes that close achievement gaps, and increase opportunities and access.”
