The 2015’ revised Special Education Currculum had about five decades since the Education Department
issued the first Special Schools Currculum in 1967. The object of the current study is to answer the
following questions based on the half-century history. First, what is the key characteristics of the change in
Korean deaf curriculum? Second, to what extent has the curriculum been appropriate? To answer those
inquiries, the author first conducted a longitudinal comparison of the deaf curriculum. In addition, the
author reviewed the literature of the appropriateness of the deaf curriculum. The results tell us that first,
the deaf curriculum has been improved in both universality and particularity. Still it faces endogenous
demand for the betterment of deaf students’ academic ability and exogenous demand for the reflection of
the societal turbulences. Second, the appropriateness of the deaf curriculum is directly related to its
achievement standard. The balance between content- and performance- standard is the key to raise the
curriculum achievement level.
