Besides, The Common European Framework of reference for languages (CEFRL) (2001) refers to assessment as broader than evaluation because any kind of assessment is a form of evaluation. CEFRL states that all language tests are a form of assessment, but there are also many forms of assessment which would not be described as tests because they can be observations or games, which would not be graded but assessed by the teacher. However, in order to consolidate the term assessment, the CEFRL offers three concepts: validity, reliability and feasibility. Validity refers to testing what has been actually taught. Reliability is when the test can be applied in any group or individual student, and has reliable results according to the rank and standard decided to the test. Finally, Feasibility is when the test takes into account the time to be developed and also the students’ abilities according to the type of test. These concepts are applied to the different types of assessment that the CEFRL suggests.
