Technology in testing: the present and the future

Computers are being used to deliver language tests. A computer-based version of TOEFL was introduced in the summer of 1998. Also, both the Intranet and the Internet are beginning to be used to deliver tests to users who are at a distance.

There are some disadvantages. Computer-based tests (CBTs) are limited in the item types, it only allows multiple-choice, gap-filling techniques and cloze. Also, reading text from screen is not the same thing as reading from print. Although Kirsch and Taylor's study found no difference between those who were familiar with computers and those who were not, all CBT TOEFL takers must undergo a tutorial to remove any possible suggestion of bias against computer illiterates.

Though there are disadvantages, there are advantages of CBT. It removes the need for fixed delivery dates and locations normally required by traditional paper-and-pencil-based testing. Results can be available immediately after the test. This has potential pedagogic advantages. CBTs, especially Internet-delivered tests, can access large databases of items. This means that test security can be greatly enhanced.

Computer-adaptive testing estimates the user's ability level on the fly. once it has reached a rough estimate of the candidate's ability, the computer can then select the next item to be presented to the user to match that emerging ability level. User are presented with items as close as possible to their ability level. However, it requires a large bank of precalibrated items. It is more user-friendly and avoid s users being presented with frustratingly difficult or easy items.

Having read the advantages and disadvanges of CBTs, I am wondering if I am a candidate of TOFEL and I can take the test whatever and whenever I am. Can others take the test for me instead of I take the test?
