Test Data Statistics

Grade information

For the period covered by this report, OET was assessed on a 5-grade scale (A to E) and reports grades for each individual sub-test . Grades for each sub-test are shown here according to a variety of classifications. OET does not report overall grades, only for each individual sub-test.

Note: for country of origin and first language, the tables show the top countries and languages, listed alphabetically, not in order of the size of the candidature.

The reliability of each sub-test is reported using Cronbach’s Alpha, which measures the internal consistency of a test. The figures below show the average reliability values for the combined administrations of the OET test per sub-test in 2017.
