    Book review Baker, D. 1989: Language testing: a critical survey and practical guide. London: Edward Arnold. iii + 1 14 pp. ISBN 0-71 31 -6538-3.

    There are by now so many different interests in language testing that books tend to be written for particular audiences, and the one comprehensive text of the traditional kind, intended to cover all requirements, is either too superficial or too massive to be viable. It is therefore worth establishing which group of readers would find this book most useful for their needs - specialists, students, teachers, learners, or combinations, e.g., teachers as students on initial or development courses. Baker considers that there is currently some confusion about the means and ends of language testing as a result of controversy between 'adherents to different schools'. I am not sure about the appropriateness of this mediaeval parallel (not how many angels can dance on the head of a pin but how many dimensions can dance under the heading of a construct?) because it seems to imply that the language testing world is one nation divided among itself into mutually antagonistic groups of theorists. I would prefer to see testing as an area in which all contributions are welcome because they help to improve thinking and, eventually, promote the student's interests. Baker's stated aim is 'to put [the] issues into perspective and to give the user or writer of language tests the necessary conceptual tools to make sound, informed decisions in this field' (p. 2). The statement is usefully specific about intentions, but 'the user or writer' could be almost anybody.

    Summarizing the areas covered should help to clarify who would find the book most useful. The first chapter is concerned with what testing is supposed to achieve, rightly emphasizing its purpose as a means of helping users to reach good decisions and suggesting that by nature it is a substitute for more complete procedures. Chapter 2 introduces four models of language test types. Baker's rather negative view of theorists leads him to start afresh with his own categorization, attempting a neutral and jargon- free description of possibilities for language test types. These are set out in a two-dimensional grid, with 'performance-referenced' and 'system- referenced' plotted against 'direct' and 'indirect'. The third chapter begins with a historical review of language testing from the second world war onwards and develops into a discussion of the 'psychometric approach', with an evaluation of its merits and disadvantages and comments on norm-and criterion-referenced assessment. Chapter 4 deals with the use and interpreta- tion of statistics, including distributions, ranking, item analysis, correlation

    and factor analysis. Chapter 5 is headed 'The integrative interlude', and includes an account of the rise and fall of the Unitary Competence Hypothesis, the structure of language proficiency and the use of cloze and dictation tests, and Chapter 6 considers 'performance-referenced' tests, both 'direct' and 'indirect' (he regards the label 'communicative' as 'probably the least helpful' description), suggesting ways in which they can be most appropriately used. Chapter 7 is concerned with the different contexts in which tests are deployed, for example the various kinds of test required within a programme of language instruction as against an external examina- tion set by a national or international body. This chapter ends with seven key questions which help to establish whether, in a given situation, a test is necessary at all, and if so what introducing it will involve. There follow short lists of references and further reading, and an index.

    The tone of the book is certainly 'critical' in the best sense: it takes nothing for granted, questioning the meanings of various approaches to testing and taking a healthily sceptical view of the use of test statistics as sole evidence about debatable points. Baker makes commendable efforts to avoid using what he regards as jargon, but (not surprisingly in view of the need to label concepts) tends to get wrapped up in some of his own, for example: 'The model for this kind of test construction resembles that of the direct test except that between the test and criterion performance are now interposed the two intermediate constructs of criterion and test proficiency' (p. 91). In any case, avoiding the common language of the field does not necessarily making things clearer, as the discussion about norm-referenced and criterion-referenced testing shows (pp. 39-40). This may seem a rather trivial level of comment, but it reflects a certain inconsistency in approach. The book seems to be attempting on occasion a somewhat academic tone, but in that case deals rather too briefly with complex issues such as difficulty levels and the implications of multiple-choice formats and is too unspecific about sources ('recent research has shown . . .'). On the other hand, if it is aimed at people who are relatively new to testing, such as teachers in training, it includes diversions such as the historical account of testing developments since the 1940s, at the expense perhaps of more guidance on test content and test writing. There are lots of good things in the book, deriving mainly from Baker's logical approach to what is involved in testing in general. But there are also many points on which I would disagree with the conclusions reached, for example that there are occasions when 'we can see how difficult a test is by just looking at it' (p. 89) and the notion that it is legitimate to calibrate a test of one skill against that of another (p. 95). There is also a tendency to oversimplify quite complex situations: 'All the test constructor has to do is to sample from this proficiency and devise a test to measure it.' All, indeed!

    On the whole, I find the book a better critical survey than practical guide. It covers a great deal of ground in quite a small space and attempts a refreshingly unbiased approach, but I am still uncertain which kind of reader would gain most from it - perhaps after all it is the 'general' book in the middle, for the non-specialist.
