Every SkillYah innovation begins with research. Our Ei5 and ii5 assessments were designed through collaboration with educators, linguists, and industry professionals. Unlike traditional tests that prioritize memorization, our approach measures real communication ability.
In 2025, we launched Japan's first bilateral language study—the largest of its kind. With over 100 beta testers, we found:
4.8/5.0 average satisfaction rating
Strong correlation between Ei5 scores and workplace performance
HR managers reported clearer hiring insights compared to traditional exams
"Real speaking ability doesn't always match high test scores. Our mission is to close that gap."
Learners gain diagnostic reports and personalized growth kits that help them understand their communication strengths and areas for improvement.
Companies improve hiring fairness and reduce bias by evaluating real communication ability rather than just test-taking skills.
Universities strengthen admissions and placement accuracy with assessments that reflect true communication competency.
Innovative assessment approach protected by intellectual property
Meeting the highest standards for organizational performance
Combining artificial intelligence with human expertise for accuracy
Validated across diverse cultural and linguistic environments
Our research is not just theory—it's transforming real classrooms, workplaces, and organizations today.
