The Korean government’s move to implement criterion-referenced assessment in
secondary schools has impacted the nation socially and politically as well as
educationally. Since education policy is a matter not of only education itself but
of a nation’s politics, culture and economy, the issue of criterion-referenced
assessment in secondary schools has been hotly debated before and even during
its implementation. With the government’s interest in implementing
criterion-referenced assessment in secondary schools, this study examined the
validity of its use using argument-based approaches to validity. Although the
government’s attempt to implement criterion-referenced assessment in second
education is worthwhile, it needs careful scrutiny with regard to the potential
positive or negative effects of the new assessment program. This study showed
how to build and support (or refute) arguments for (or against) the use of
criterion-referenced assessment in the domain of English language subjects from
various aspects. More specifically, it illustrated how to pose proper research
questions based upon theoretical underpinnings of argument-based approaches to
validity. By clarifying these issues, it is hoped that this study provides a better
all-around understanding of criterion-referenced assessment in secondary English
education and assessment in Korea.
