Advancing behavior-development expertise with AI-powered training.

The QBA is a mastery-level supervisor credential for designing and overseeing programs, while the QASP-S is an intermediate-level supervisor credential for implementation guidance and training. The QBA requires a master's degree or higher to sit for the exam, and the QASP-S a bachelor's degree or higher. Required coursework also differs—270 hours for QBA and 188 hours for QASP-S—as does fieldwork: 2,000 hours for QBA and 1,000 hours for QASP-S. Both credentials require passing the QABA-approved computer-based (CBT) exam.

Yes. You can earn the QBA credential online from Korea. As a QABA-approved coursework provider, SpectrumHub helps you complete every step—from coursework to the exam—within Korea, with Korean-language learning support, 1:1 matching with a qualified supervisor, and mock exams and study materials. The exam is computer-based (CBT).

Coursework is a QABA-approved online curriculum you complete at your own pace through video lectures, readings, and quizzes. For supervision, you are matched 1:1 with a qualified supervisor for regular meetings and case reviews. All learning and fieldwork records accumulate in our own learning-management system, so you can use them directly when applying for your credential.

Credentialing costs arise in stages—coursework, supervision, and the exam fee—and vary by enrollment timing and package. Enrolling all at once through a cohort package costs less than the sum of individual items, and we also offer scholarship benefits for selected applicants. For exact pricing, we'll guide you through our KakaoTalk 1:1 channel consultation.

It depends on the credential. ABAT typically takes 1–2 months (entry level, 40 hours of coursework), QASP-S 8–12 months (intermediate level, 188 hours of coursework + 1,000 hours of fieldwork), and QBA 15–24 months (mastery level, 270 hours of coursework + 2,000 hours of fieldwork). Timelines vary with your learning pace and available fieldwork hours, and SpectrumHub supports you in progressing at your own pace.

Beyond group enrollment of an organization's professionals, we run a partnership model in which the organization itself registers as an internationally accredited institution—serving both as in-house workforce training and as a reputational asset.
