Most scholars consider the birth of modern language testing as a field of study to be the year 1961 with the publication of Robert Lado's book Language Testing and John Carroll's chapter `Fundamental Considerations in Language Testing'.
In the decades since it has grown in scope into a deeper and wider theoretical and intellectual field of study.
The intellectual growth has come with the birth of psychometrics, specifically, in using statistical analyses for test development and research; with ideas from linguistics, in developing language tests that are communicatively oriented; with ideas from ethics, specifically, in developing qualities, codes, and standards so that tests are fair and just.
This has been coupled with the growth of the field into a billion-dollar worldwide enterprise partly fuelled by the practical need to assess the English language ability of test-takers who want to study at English-medium universities or work in offices that mainly use English for communication. This new four-volume collection from Routledge captures this burgeoning field by offering a cogent and comprehensive state-of-the-art coverage of the very best material.
The volumes have been conceptualized both as a scholarly contribution in terms of theories and research as well as a practical guide in terms of test development in the field of language testing and assessment.
