This book investigates the influence of test taker characteristics on
performance in tests of English as a foreign language by exploring the
relationships between these two groups of variables. Data from a test
taker questionnaire and performance on the First Certificate in English
(FCE) and the Test of English as a Foreign Language (TOEFL) were used
for the study. The research was conducted in a construct validation
context and aimed to increase our understanding of the individual
differences among test takers that influence their test performance. The
application of a structural modeling approach to investigate the
influence of test taker characteristics on test performance makes this
study a valuable contribution to language testing research. As such, it
will be of considerable relevance to academic researchers and graduate
students in the field of language testing and assessment, as well as to
others interested in second language acquisition and learning.
