This study was primarily carried out to obtain a basic information in the internal (domestic) test method by comparing the current circumstance of internal test with that of foreign test. Data from Korea, England, Denmark, U.S.A. and West Germany were analysed. The results are summarized as follows; 1. It appears that the change of current test type from individual performance test to sib or progeny test is required for estimation of carcass performance. 2. Although no significant difference was found in terms of listed condition for the pig to be tested among 6 conturies, future consideration should be taken in reproductive performance such as the number of teats, and prevention of diseases. 3. The alteration in the type of pig test may be an initial step for the changes of test items due to its close link to test items. However one should purse an objective estimation for the performance of lean meat production. 4. It is suggested that the effect of stepwise change of the nutrition level during the test period should be examined for the estimation in the performance of the lean meat production. 5. Since higher proportion of lean meat may be required of the introduction of the carcass classification and pork export, there should be reconsideration about the current off-test weight ($lt;90㎏).
