Abstract

The evaluation of validity of a language certificate is of major importance in the field of language testing. Thus the present study evaluates the validity of the Greek state certificate of English language proficiency (KPG) via two different statistical methods which are Principal Components Analysis and Implicative Statistical Analysis. There were 141 candidates’ responses analysed. A comparison of the results is discussed and the advantages and disadvantages of each method are evaluated. Implications for testing methods and future validation methodologies and issues are also considered. The application of the two distinct methods allows data analysis and designates different aspects of the results. Consequently, their combination offers a more detailed and a more complete analysis and data investigation, contributing thus to more detailed conclusions being drawn.
