The Principles of Language
Assessment and The Use for Daily Classroom
Brown (2004)
in his book, “Language Assessment: Principles and Classroom Practices
“mentioned five major principles of language assessment which consist of
practicality, reliability, validity, authenticity, and washback.
- Practicality refers to tests that should be true. A practical test considers not only the limitation of budget and time, but also has clear administration, scoring, and interpretation.
- Reliability refers to tests that are consistent and dependable. Students or groups of target students are given the same test in two different periods of time, the test result would be similar. For test-takers, they are not ambiguous to a given field of study. Also, a reliable test not only gives learners clear directions but also offers administrated rubrics for grading or evaluation.
- Validity is talks about a test which “is valid if it is measured what it is supposed to measure” and when it is used for the purpose of assessment. Brown pointed out that a valid test should measure according to its purpose, but not “irrelevant or contaminating variables”. Thus, a test’s meaningful information for criterion, and evidence of performance should be considered in order to measure a student’s learning ability. Furthermore, there are many ways to measure the validity of a test, including content validity, construct validity, criterion-related validity (concurrent & predictive) and face validity.
- Authenticity emphasizes that language is natural, contextualized and meaningful. Besides, authenticity offers language theme-based organization, story-line, or episode to reproduce real-world tasks.
- The last principle is washback which refers to “criterion for a test is the influence of the form and the content of the test” in the classrooms. This is also what Hughes (2003) said,” the effect of testing on teaching and learning”.
