TESTS
A TEST is an activiity whose main purpose is to convey how well a test-taker knows how to/ can do something.
Reasons for testing
- to gain information how much Ss know and what to do next
- information how much Ss know for Ss
- asses for purpose external to current teaching
- motivate Ss
- review knowledge and skills
- punish Ss
- practice
- give Ss a sense of achievement
- get Ss to make an effort
- give Ss a sense of structure (signal that a “stage” in learning has been reached, such as finishing a coursebook unit, covering a lexical / grammatical area, etc.)
Classification of tests
According to | Types of tests | Comments |
Frame Reference | norm-referenced |
|
criteria-referenced |
| |
Purpose of Test (information being sought) | proficiency | criterion-referenced; measures Ss’ abilities in using language to perform particular tasks |
achievement | measures Ss’ mastery of the syllabus or content covered | |
diagnostic | measures the level of particular sub-skills, aspects of grammar, lexis, pronunciation. It may diagnose learning difficulties. | |
placement | criterion-referenced; identifies candidates who meet requirements for particular groups / classes. | |
Number of language elements tested at a time | discrete point (one element) |
|
integrative (more elements) |
| |
Score | objective | key |
subjective |
| |
Test Construction | direct |

indirect |

TEST VALIDITY is the extent to which a test measures what it is supposed to measure (and nothing else).
Test Validity (types):
- face validity - perceived, surface credibility, “test appeal”
- content validity - representative sample of the course
- construct validity - designed in accordance with the current language teaching theory
- criterion-related validity - concurrent and predictive (comparing the test results with some other measure)
Test Reliability
A reliable test produces consistent results when administered on different occasions.
Factors affecting test reliability:
- the extent of the sample of material selected for testing
- administration conditions
- test instructions
- personal factors (e.g. illness, motivation)
- scoring the test
A valid test ensures a certain degree of reliability.
How to design a reliable and valid test? Some hints:
- ensure questions do not allow freedom of interpretation
- give Ss as many opportunities as possible
- provide clear and specific instructions
- avoid ambiguous items
- make sure the test is as objectively scored as possible
- the fewer choices regarding questions, the better
- make sure Ss are familiar with tasks / test type
- agree on a marking key
- provide double marking when tasks are subjective
- ask your colleagues for feedback
Test Practicality
The degree of practicality depends on how easy and cheap the test design, administering and scoring are.
Wash-Back Effect
The Wash-back Effect is the effect of testing on teaching and learning.
Basically, this effect may be beneficial, harmful or (hardly ever) neutral.
How to make the Wash-Back Effect beneficial?
- test the abilities whose development you want to encourage
- sample widely and unpredictably
- use direct testing
- use criterion-referenced test frame
- base achievement tests on objectives
- ensure the test (type) is known and understood by Ts and Ss
Types of test according to their purpose
Course tests
Final achievement test - takes place at the end of the course; measures Ss’ mastery of the syllabus or content covered.
Progress test - conducted throughout a course; measure sSs’ achievement since previous test.
Quiz - informal “small” test; encourages; provides feedback.
Other tests
Proficiency test - criterion-referenced; measures Ss’ abilities in using language to perform particular tasks.
Selection test - norm-referenced; identifies best candidates.
Placement test - criterion-referenced; identifies candidates who meet requirements for particular groups / classes.
Diagnostic test - measures the level of particular sub-skills, aspects of grammar, lexis, pronunciation. It may diagnose learning difficulties.
Common test errors:
- the test tests:
- certain mental ability instead of language knowledge
- background knowledge instead of language knowledge
- two things at a time
- problems with distractors:
- easy to eliminate
- of different types (e.g. phonological and lexical)
- inconsistent
- nonsense (elementary levels -> exposure to wrong language; advanced levels -> easy to eliminate)
- there’s more than one correct answer
- the answer is embedded in the question
- difficult scoring
- lack of content
Test Design
1. Specifications of the test
- what to test
- how to test
- how many test items
- how to score
2. Item writing and moderation
- method effect (the method of testing affects ss’ score)
Make sure you use more than 1 method for testing any ability.
3. Pre-testing and analysis
Try to test another (not target) group.
4. Administration
- testing environment
- giving instructions
- maintain the environment
- collect the papers
5. Scoring
- objective versus subjective
- holistic versus analytic
6. Reporting and integrating scores
- seperately or altogether
- cut-off points
7. Test analysis
- comparing the test to previous ones
- common difficulties may stem from unclear instructions
8. Developing and improving tests
