ILTO uses recycled test items from the Test of English Communication Skills – TECS, which have been calibrated, validated and psychometrically audited. Since the item bank for the TECS is replaced to assure that test takers do not memorize the questions, these items are used in the EDE in order for the test taker to familiarize with the TECS.

This test may be taken in in a non-secure environment, without any proctor and may be done anywhere. It is also used as a placement test or entry test.

The EDE is not an international certification and thus, ILTO is not accountable for the real result of this test. For a more comprehensive international standardized test certificate, ILTO suggests the TECS (Test of English Communication Skills) which is taken in a secure environment, with a fraud prevention code that prevents any kind of plagiarism or abnormal situation and issues an official certificate supported by ILTO.
