Abstract
The alternate form test-retest reliability coefficients estimated for the TOEIC® Speaking and Writing tests from this study are considered reasonably high and acceptable for their intended purposes. Factors such as the reduction of score range and homogeneity of groups, however, should always be considered when trying to interpret and use the data. This paper is part of the Research Foundation for TOEIC: A Compendium of Studies, published by ETS in 2010.
