OET reports a scaled score (from 0 to 500) and a letter grade (from E to A) for each individual sub-test. OET does not report overall scores or grades.

Note: In these sets of data, Nationality and First Language statistics are self-reported by candidates. Nationality may indicate where candidates are currently residing or from where they have immigrated, therefore, it is not an indicator of what language a candidate might speak or their proficiency in English.

Nationality may not correlate to proficiency of the official or common languages spoken in that country. First language is not an indicator of what a candidate’s proficiency in that self-reported first language might be; it also does not take into account other languages that candidate may possess.

The reliability of the Listening and Reading sub-tests is reported using Cronbach Alpha, and the reliability of the Writing and Speaking sub-tests is reported using Spearman Reliability. The figures below show the average reliability values for the combined administrations of the OET test per sub-test in 2021. Also provided are conditional reliability figures at C+ and B, which are the score points at which decisions are typically made.
