With a mention in the new National Cyber Workforce and Education Strategy and even a dedicated state law , K–12 cybersecurity education clearly has the eye of policymakers. However, despite public attention and new opportunities for high school students to pursue cybersecurity coursework, high schools often struggle to provide students with a clear understanding of what cybersecurity careers actually look like. Hands-on learning experiences, like those we’ve had at our schools and during our internship with NICE at NIST, can help bring cybersecurity education and career pathways into focus for
