The purpose of this study was to develop and apply the K-PSI test on the Korean population. K-PSI sentences in the Format I and II were developed, each consisting of 18 words and 12 sentences at 3-year-old difficulty level. The standardization results showed that the performance was 100% for children aged 3 years or more. Reliability and validity tests of K-PSI revealed that it is considered as an effective tool to measure early speech perception level in hearing-impaired children.
