NAEP Device-Agnostic Research: Designing an Assessment Experience that Works Anywhere


NAEP Device Agnostic Research

When the National Assessment of Educational Progress (NAEP) explored allowing students to take assessments at home during COVID, the design team faced a critical question: How can we create a device-agnostic experience that works equally well on phones, tablets, and computers?

My Role


As the Lead UX Strategy & Research, I conducted a short mixed-method study to understand the range of devices students actually use, how many they have access to, and how socioeconomic factors influence their technology use.

Study Approach


To gather quick, relevant data, I recruited participants through local Facebook groups in Hilliard, Ohio. Parents provided information about their children’s ages and primary devices.

In total, 63 students (ages 10–18) reported 98 total devices.

The study explored:


  • What devices students currently own or use
  • How many devices each student uses
  • How socioeconomic status affects school-related device use
  • The prevalence of hand-me-down devices

Key Findings


  • iPhones dominated — 50% of all devices, and 71% of “one-device” users relied on them.
  • Over half (55%) of students had only one device.
  • 12% used a hand-me-down device, most often iPhones or MacBooks.
  • Lower-income students were more likely to rely on phones rather than laptops for schoolwork.

Design Implications


These findings directly shaped NAEP’s prototype direction. We prioritized:


  • Responsive layouts that adapt to any screen size
  • Touch-friendly navigation for mobile users
  • Simplified task flows to reduce device-based friction

By grounding design in real-world device data, the team could ensure NAEP’s assessment tools were not only accessible but truly device-agnostic — giving every student an equal opportunity to succeed, no matter what technology they have at home.
