- RELIABILITY: The test should produce consistent results over time or across different occasions when administered under similar conditions.
- STANDARDISATION: The test should be administered, scored, and interpreted in the same way for everyone to ensure fairness and accuracy.
- OBJECTIVITY: The scoring and interpretation should not depend on the examiner’s personal judgment or bias.
- NORMS: A good test provides average scores or standards (norms) that allow comparison of an individual’s performance with that of a larger group.
- PRACTICALITY: The test should be easy to administer, score, and interpret without requiring too much time, cost, or effort.

- Attitude tests eg Situational Judgment tests, Likert scale
- Emotional intelligence tests eg Mayer Salovey Caruso emotional intelligence test
Process of psychological testing

What are psychological topologies?
Psychological topologies are classifications used by psychologists to describe the differences between people.
4 types of classifications
- Geographical classification: This involves grouping psychological data based on location or region. For example, test results may be classified according to countries, states, or urban vs rural areas to compare psychological traits or behaviors across different environments.
- Chronological classification: This refers to organizing data according to time or age. In psychological testing, individuals may be grouped by age (e.g., children, adolescents, adults) or by time periods (e.g., before vs after treatment) to observe developmental or temporal changes.
- Quantitative classification: This is the classification of data based on numerical values or measurable quantities. In psychology, this includes scores from tests (e.g., IQ scores, anxiety levels), which can be grouped into ranges or categories like high, average, or low.
- Qualitative classification: This involves grouping data based on non-numerical characteristics or qualities. In psychological testing, individuals may be classified by traits such as personality type, gender, emotional state, or diagnostic categories (e.g., depressed vs non-depressed).
What is test construction?
Test construction is the systematic process of designing, developing, and standardizing a psychological test to measure a specific psychological trait, ability, or behavior accurately and reliably.
5 stages of test construction
- Planning
- Writing
- Testing
- Trying
- The use of the test
Key points in test construction
- Planning
- Defining the test
- Selecting a scaling method
- Constructing the items
- Item analysis
Sources of psychological tests
- Academic databases eg PsychINFO
- APA psych test
- Professional resources
- Test publishers
- Primary sources like journals, projects, books, dissertations, thesis, academic library etc
Procedure for questionnaire construction
- Decide the information required
- Define the target respondent
- Choose the method of reaching your target respondent
- Decide on question content
- Develop the question wordings
- Put questions into a meaningful order and format
- Logically order questions
- Design the layout
- Pilot test the questionnaire
Limitations to test development in Nigeria
- Lack of skilled manpower and members
- Insufficient funds
- Time constraints
- Work overload
- Cultural bias of foreign tests
