The 14 conference papers and discussion transcripts in this volume were arranged to suggest both an outline of the state of the art of foreign language testing and a practical guide for test writers and users. The first two papers (T.R. Hopkins, Language Testing of North American Indians; and E.J. Briere, Testing ESL Among Navajo Children) deal with specific groups. A paper by D.A. White (Second Language Testing Requirements of the Canadian Public Service Commission) shows the vast range of problems and their consequences. Two papers present models of language behavior (L.A. Jakobovits, Dimensionality of Compound-Coordinate Bilingualism; and R.L. Cooper, An Elaborated Language Testing Model). The three following papers discuss testing variables and instrumentation (P. Pimsleur, Aptitude Testing; B. Spolsky et al., Preliminary studies in the Development of Techniques for Testing Overall Second Language Proficiency; and T. Plaister, Testing Aural Comprehension). Test validity is dealt with in papers by R.M. Valette (Evaluating Oral and Written Communication), E.G. Lewis (International Education Assessment--English as a Foreign Language), and E. Ingram (Testing in the Context of a Language Learning Experiment). Finally, two papers discuss classification of tests (W.F. Mackey, The Typology, Classification and Analysis of Language Tests; and J. Savard, A Proposed System for Classifying Language Tests). A summary of the conference was written by L.A. Palmer. (JD)
