English skills alone are only part of the big picture however, and a small one at that it seems. However, it must be noted that it is still a weak correlation. "The results of this study show that IELTS scores are at the minimum just as valid as TOEFL scores for predicting academic success, which may help for decisions being made about which test scores to accept. At least the DET leaves part of that assessment to the university, since it will weigh part of your suitability in the unscored sections.įrom research done on IELTS, for example by Researchers from the University of Western Ontario So, for that issue, you may need to judge for yourself. Well, that remains to be seen, but there is little evidence IELTS, TOEFL, PTE, CanTEST or CAEL is any more a valid predictive tool for university success. In pain English, that means how well does this test tell you or the University that you can handle studying and handling university English demands? Reliability of a test is one issue but perhaps the more important issue is how predictively valid the DET is. These are good figures if they hold up in subsequent research. When a person retests, the person will get the same score about 86% of the time. This indicates that with two runs of the same test taker, it will be the same score at about 96%. These results suggest that the certified DET scores are very reliable" ".internal consistency reliability coefficients are both 0.96, and the test-retest reliability coefficient is 0.84 with only a small effect size in score change. It does provide research to show high reliability and unlike other tests, they make this research very available for others on their website DET does provide assurance that accents will not be punished and that hasty judgments will not be made. However, in other areas that require judgment you may feel wary. There are sections when this does not seem problematic and this is becoming standard practice with many other tests such as PTE. The whole scored sections of the test is marked based on an algorithm. It is a worthwhile alternative but you need to understand its features:
Duolingo test is a new more affordable option that is being accepted at a number of universities around the world.
