Principles of language assessment "test"
Practicality
has clear directions for administration
appropriately utilizes available human resources
can be completed by the test-taker within appropriate time constraints
does not exceed available material resources
stays within budgetary limits
considers the time and effort involved for both design and scoring
Washback
offers learners a chance to adequately prepare
gives learners feedback that enhances their language development
positively influences what and how learners learn
is more formative in nature than summative
positively influences what and how teachers teach
provides conditions for peak performance by the learner
Validity
is supported by a theoretical rationale or argument
Content-Related Evidence
offers useful, meaningful information about a test-taker's ability
Criterion-Related Evidence
involves performance that samples the test's criterion (objective)
Construct-Related Evidence
relies as much as possible on empirical evidence (performance)
Consequential Validity (Impact)
does not measure irrelevant or "contaminating" variables
Face Validity
measures exactly what it proposes to measure
Reliability
contains items/tasks that are unambiguous to the test-taker
Student-Related Reliability
lends itself to consistent application of those rubrics by the scorer
Rater Reliability
has uniform rubrics for scoring/evaluation
Test Administration Reliability
gives clear directions for scoring/evaluation
Test Reliability
is consistent in its conditions across two or more administrations
Authenticity
includes meaningful, relevant, interesting topics
provides some thematic organization to items, such as through a story line or episode
has items that are contextualized rather than isolated
offers tasks that replicate real-world tasks
contais language that is as natural as possible
