Direct and indirect testing image

is not excessively expensive

is relatively easy to administer

has a scoring/evaluation procedure that is specific and time-efficient

stays within appropriate time constraints

if a test is consistent and dependable

Most common learner-related issue

temporary illness, fatigue, a "bad day", anxiety, physical or psychological factors

Like human error, subjectivity, and blas may enter into the scoring process. Inter-rater reliability occurs when two or more scorers yield inconsistent scores of the same test

Conditions in which the test is administered

outside noise, photocopying, variations in room temperature, amount of light in different parts of the room and conditions in desks and chairs

Sometimes the nature of the test itself can cause measurement errors.

if a test is too long, time test

The extent to which inferences made from assessment results are appropriate, meaningful, and useful in terms of the purpose of the assessment

Face Validity image

Authenticity image

indirect test, learners are not performing the task itself but rather a task that is related in some way

direct testing involves the test-takers in actually performing the target task

if you can clearly define the achievement that you are measuring

the extent to which the "criterion" of the test has actually been reached

Consequential Validity image

Washback image

the effects the test have on instructions in terms for the test

the task is likely to be enacted in the "real word" image

accompasses all the consequences of a test, its accuracy, its impact and the (intended and unintended) social consequences of a test's interpretation and use

will likely be high if learners encounter

directions that are crystal clear

taks that related to their course work

items that are clear and uncomplicated

a test that is clearly doable within the allotted time limit

a difficulty level that presents a reasonable challenge

a well constructed, expected format with familiar tasks

the psychological state of earner (confidence, anxiety) is an important ingredient in peak performance by a learner
