Introduction Language testing for higher education is extremely widespread, and most of it is English testing for academic purposes. Score users are normally academic institutions who wish to know whether an international student has the language abilities necessary to succeed in an academic environment. Of course, an admissions tutor in a University will take many factors into account when making a decision. These factors may include previous learning experience and evidence of content knowledge, references from previous teachers, personal statements, and even indications of personability, ability to work with others, and enthusiasm. If the applicant is a postgraduate it is common to take into account the ranking of the University from which they received their first degree. In addition, the tutor will wish to be reasonably certain that the applicant will be able to read the texts expected of first year students, take part in seminars, tutorials and lectures, and crucially to write assignments in the relevant academic genre. Universities offer both pre- and in-sessional language support programmes that may provide additional assistance. Students are frequently referred to such programmes if their scores on the language test are within the error range of the established cut-score for admission.
Testing English for Academic Purposes (EAP) is now a huge industry. The first thing we need to consider is just why English has become the primary language of higher education, not only in countries where English is the first language, but increasingly around the world (see this paper by Coleman on the use of English in Europe). In his book English as a Global Language, and this YouTube video, David Crystal argues that it is because of power: the language of science and the language of economics has been English for the last 400 years. This has given English, and English medium Universities, both status and advantage. Studying in these Universities has therefore become a goal of more and more international students, as their programs are perceived to provide more opportunities and career enhancement. As a result English language testing has expanded rapidly and is now a multi-million pound industry with the main test providers competing fiercely for market share.
TOEFL
The Test of English as a Foreign Language (TOEFL) was originally developed in the 1960s, but underwent a major retrofit in readiness for the release of the internet based test (iBT) in 2005. You can read about the retrofit in a book by Chapelle et al. (2008). ETS has long developed tests for University access, including the GRE and the College Board's SAT. In this YouTube video, released by ETS for its 60th anniversary, the CEO of the company explains the rationale behind the work: to provide meritocratic means of giving access to Universities - an aim that goes back to the 1930s. The TOEFL iBT is a linear test, even though its CBT predecessor was computer adaptive. Other novel features include the use of integrated tasks. The format is as follows:

IELTS
Similarly the International English Language Testing System has undergone many retrofits since its inception in the late 1970s. Much of this is documented in Davies (2008), which also contains sample test tasks from various versions of the test. IELTS had two forerunners in the United Kingdom. The first was the English Proficiency Test Battery (EPTB), which was developed in the 1960s by Alan Davies. This was superseded by the English Language Testing Service in the late 1970s. ELTS differed from IELTS primarily in the provision of subject-specific modules in additional to a general academic module: life sciences, medicine, physical science, social studies, and technology. Following a number of studies, including an ELTS validation study, IELTS was launched in 1989. The major change was the removal of the subject specific (ESP) modules, primarily because research had shown that given the generality of the material in the test, subject specific knowledge did not provide an advantage on a subject specific test (Clapham, 1996). Further retrofits have taken place at intervals since its introduction. The format is as follows:
Section

Listening

Sample materials are available from the test producer. Research Reports are also freely available.
Pearson PTE The PTE Academic was rolled out in 2009 with the explicit aim of taking market share away from the two established tests (see the review of 2009). It differs from the others primarily in the fact that testing is 'on demand' rather than on set test dates, and the scores are issued within 5 working days. This speed is achieved through the use of automated scoring, even for the speaking component. For an introduction to automated scoring see the video on this topic by Xiaoming Xi. PTE Academic also claims to have the most advanced biometric test security system to ensure that ghost writers cannot take tests on behalf of others. The format of this computer based test is as follows:

Testing and Immigration
In many European countries and Australia language testing for University entrance has become wrapped up in immigration policy (see Extra et al., Hogan-Brun et al., and Slade et al.). This is partly because countries have tried to attract students into higher education with the promise that on graduation they may stay and work, and that their spouses may obtain a work permit while they are studying. When the financial and economic climate is not so good these are usually withdrawn. Also, a reduction in student numbers is one of the few ways that governments can be seen to control immigration. In this news clip from the United Kingdom the controversy is clear. On the one hand students are seen as vital to the economy, while on the other politicians wish to restrict student visas and insist that students return home at the end of their studies. The use of set scores on language tests as a criterion for issuing student visas is the easiest way to implement such policies, but it is a highly controversial practice.
For Discussion
The primary users of language test scores for higher education are admissions tutors. Do a Google search on 'admissions tutor': what precisely is their job? Can you think of other kinds of information they may take into account apart from those listed above? What are the consequences of making a poor decision?
Look at sample materials from the three tests mentioned on this page, along with the overview of the test from the website of the test provider. In what ways are they similar? How is each one distinctive? Are there any features that you think are particularly attractive or problematic?
Each of the tests listed on this page publishes research into the validity of the test for its intended purpose. What kinds of evidence does each present? Select one piece of research and write a critical review.
Tests are designed for particular purposes. The constructs, skills, abilities or knowledge that the test is designed to measure are defined in the test specifications. The tests described on this page are all intended to serve the same decision making purpose. For this reason decision makers sometimes wish to have score comparisons, like this one produced by ETS: Score Comparison Tool. You can also find a link on this page to the research conducted to construct this tool. Why do you think admissions tutors wish to have this kind of information even though it is very difficult to compare results on tests that are not generated by the same specifications?
Look at the news links on the right side of this web page. Choose one or two that look interesting and/or controversial. What are the issues that are of concern to the wider public in language testing for University entry?
Using these language tests in immigration policy is highly controversial and raises many ethical issues. But as Bishop (2004) correctly argues there is nothing in the Standards for Educational and Psychological Assessment, or even the ILTA Code of Ethics, that clearly makes such use unethical. Yet, it makes many language testers uneasy. Why do you think this is the case? What is your position on this use of tests?
When designing domain specific tests it can be useful to have access to a corpus like the Michigan Corpus of Academic English (MICASE). Look at examples of specific speech events from this corpus. How might you use this data in researching a test of spoken academic English?
