Psychometrics: The Science of Measuring Psychological Abilities and Problems
Types and Categories of Psychological Tests
Psychological tests are classified into different types and categories based on various criteria, such as the purpose, content, format, administration, scoring, and interpretation of the test. In this article, we will explore some of the most common types and categories of psychological tests and their characteristics.

Purpose-Based Classification
One way to classify psychological tests is based on their purpose or goal. Some of the main purposes of psychological testing are:
Ability Tests: These tests measure cognitive abilities, such as intelligence, aptitude, achievement, memory, or creativity.
Personality Tests: These tests measure personality traits, such as interests, values, attitudes, motives, or preferences.
Clinical Tests: These tests measure psychological disorders, such as depression, anxiety, schizophrenia, or autism.
Neuropsychological Tests: These tests measure brain functions, such as attention, perception, language, or executive skills.
Forensic Tests: These tests measure legal issues, such as competency to stand trial, criminal responsibility, or risk assessment.
Educational Tests: These tests measure academic skills, such as reading, writing, math, or science.
Occupational Tests: These tests measure vocational skills, such as aptitude for a specific job or career.
Content-Based Classification
Another way to classify psychological tests is based on their content or domain. Some of the main domains of psychological testing are:
Cognitive Domain: This domain covers mental processes that involve thinking, reasoning, learning, problem-solving, or decision-making.
Affective Domain: This domain covers emotional processes that involve feelings, moods, motivations, or attitudes.
Behavioral Domain: This domain covers observable actions that involve physical movements, speech, gestures, or expressions.
Social Domain: This domain covers interpersonal processes that involve communication, interaction, relationship, or group dynamics.
Biological Domain: This domain covers physiological processes that involve brain structures, neural pathways, hormones, or genes.
Format-Based Classification
A third way to classify psychological tests is based on their format or structure. Some of the main formats of psychological testing are:
Paper-and-Pencil Tests: These tests require the test-taker to write or mark their responses on a paper sheet or booklet.
Computerized Tests: These tests require the test-taker to use a computer or an electronic device to enter their responses.
Performance Tests: These tests require the test-taker to perform a task or an activity that demonstrates their skills or abilities.
Projective Tests: These tests require the test-taker to interpret ambiguous stimuli such as inkblots, pictures, or words, and reveal their personality or unconscious thoughts.
Objective Tests: These tests have clear and definite stimuli, such as multiple-choice, true-false, or matching items, and have standardized scoring and interpretation procedures.
Subjective Tests: These tests have vague and open-ended stimuli, such as essay, short-answer, or fill-in-the-blank items, and have flexible scoring and interpretation procedures.
Administration-Based Classification
A fourth way to classify psychological tests is based on their administration or delivery. Some of the main modes of administration of psychological testing are:
Individual Tests: These tests are administered to one person at a time by a trained examiner who observes and records the test-taker's responses and behavior.
Group Tests: These tests are administered to several people at the same time by a proctor who instructs and monitors the test-takers' responses and behavior.
Self-Report Tests: These tests are administered to the test-taker by themselves, who reads and responds to the test items without any external guidance or supervision.
Observational Tests: These tests are administered to the test-taker by an observer, who watches and records the test-taker's behavior in a natural or controlled setting.
Situational Tests: These tests are administered to the test-taker by a simulator, who creates and manipulates a realistic scenario or environment that elicits the test-taker's behavior.
Scoring-Based Classification
A fifth way to classify psychological tests is based on their scoring or evaluation. Some of the main methods of scoring of psychological testing are:
Norm-Referenced Tests: These tests compare the test-taker's score to the scores of a representative sample of people who have taken the same test before.
Criterion-Referenced Tests: These tests compare the test-taker's score to a predetermined standard or criterion of performance.
Ipsative Tests: These tests compare the test-taker's score to their own previous scores or to their own expectations or goals.
Qualitative Tests: These tests use descriptive or narrative methods to evaluate the test-taker's responses or behavior.
Quantitative Tests: These tests use numerical or statistical methods to evaluate the test-taker's responses or behavior.
Interpretation-Based Classification
A sixth way to classify psychological tests is based on their interpretation or meaning. Some of the main approaches to interpretation of psychological testing are:
Nomothetic Interpretation: This approach uses general principles or theories to explain the test-taker's responses or behavior.
Idiographic Interpretation: This approach uses individual factors or contexts to explain the test-taker's responses or behavior.
Mechanistic Interpretation: This approach uses causal or deterministic factors to explain the test-taker's responses or behavior.
Organismic Interpretation: This approach uses holistic or dynamic factors to explain the test-taker's responses or behavior.
Ethical Interpretation: This approach uses moral or value-based factors to explain the test-taker's responses or behavior.
Conclusion
In conclusion, psychological tests are diverse and complex instruments that measure various aspects of human behavior, cognition, personality, and mental health. They can be classified into different types and categories based on various criteria, such as purpose, content, format, administration, scoring, and interpretation. Understanding these types and categories can help psychologists and other professionals select, use, and evaluate psychological tests appropriately and effectively.
