Although direct testing is now widely accepted as the best way to evaluate students’ speaking and writing skills, the fact remains that these types of tests are much more difficult to mark objectively than, for example, multiple choice questions.
Awarding one mark or score for a speaking or writing test based on the examiner’s overall impression is clearly subjective. A more objective alternative involves analyzing different aspects of a student’s speaking or writing and allocating a score for each of these areas.
For example, the IELTS speaking and writing tests use detailed ‘band descriptors’ from 0 to 9, which cover all levels from A1 to C2 on the CEFR.
In the speaking test, candidates are awarded a score for each of the following areas:
* Fluency and coherence
* Lexical resource
* Grammatical range and accuracy
* Pronunciation

* Task achievement
* Coherence and cohesion
* Lexical resource
* Grammatical range and accuracy
