PSY-335 at Southern New Hampshire University introduces the main kinds of psychological tests and how they are built and used.
The catalog says students are introduced to a variety of tests as measures of personality, intellectual functioning, cognitive functioning and attitudes, and gain knowledge about the types of tests and techniques available, the construction of tests, and the ethical issues that may arise.
The listed prerequisite is either PSY-223 Research I: Statistics for Psychology or PSY-260 Statistical Literacy in Psychology. Students find the course demanding because evaluating a test needs both statistical ideas and careful ethical judgment.

What PSY-335 Covers
The catalog names three learning areas and four things tests can measure.
| Area | What to understand |
|---|---|
| Types of tests and techniques | What kinds of test exist and when each is appropriate |
| Test construction | How items are written, tried out, scored and refined |
| Ethical issues | Consent, confidentiality, fairness, misuse of scores and qualifications to administer |
| Personality measures | What self-report and other approaches claim to capture |
| Intellectual and cognitive functioning | What ability tests measure and what they leave out |
| Attitudes | How opinions and beliefs are measured |
Key Ideas Explained
Reliability
A reliable test gives consistent results: the same person tested again, or scored by a different rater, should get similar results. Know the main ways of checking this and what each shows.
Illustration: A questionnaire gives very different scores for the same person on two days a week apart. That points to a reliability problem, so a user should be cautious about using the scores to make decisions.
Validity
A valid test measures what it claims to measure. Reliability is necessary but not enough, so a consistent test can still measure the wrong thing.
Fairness and Ethics
Consider whether items work equally well for people from different backgrounds, and who should be allowed to administer and interpret a test. Scores should support decisions, not make them alone.
Typical Assignments and How to Approach Them
The catalog does not list graded assessments. These are typical for a testing course; confirm yours in the course.
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Test evaluations | Judging a test on quality criteria | Describe the purpose, then assess reliability, validity, norms and fairness |
| Comparison papers | Contrasting two measures | Use the same criteria for both and finish with a reasoned preference |
| Ethics cases | Applying professional standards | Identify the issue, the standards involved and the responsible action |
| Discussion posts | Explaining concepts with examples | Define the term, give a short example, mention a limit |
Where Students Get Stuck
- Confusing reliability and validity. Remember consistency versus accuracy of meaning.
- Treating scores as facts about people. Scores are estimates with error.
- Weak statistics. Revisit the ideas from your prerequisite, such as correlation and distributions.
- Ignoring norms. A score only makes sense compared with an appropriate reference group.
- Using unpublished or unvetted tests. Choose well-documented instruments for evaluation tasks.
Evaluating a Test
| Criterion | Question to ask | Evidence to look for |
|---|---|---|
| Purpose | What decision is the test meant to inform? | Manual or published description |
| Reliability | Are scores consistent? | Reported reliability evidence |
| Validity | Does it measure what it claims? | Studies linking it to other measures or outcomes |
| Norms | Who was the comparison group? | Sample details |
| Fairness | Does it work across groups? | Bias studies, accessibility |
Writing a Test Review
A good review reads like a short report. Begin with what the test claims to measure and for whom. Then summarize the evidence on reliability and validity, describe the norm group, and note any concerns about fairness or misuse.
End with a judgment: for which purposes would you recommend the test, and for which would you not? A balanced conclusion that names a suitable and an unsuitable use usually shows stronger understanding than a simple pass or fail verdict.
Common Errors in Test Discussions
Three errors recur in student work. First, calling a test valid or reliable in general: these are properties of scores for a particular use. Second, quoting a score without its norm group. Third, treating a single test as sufficient for a decision about a person.
Avoid all three by stating the use, the comparison group and the other information that should accompany the score. This phrasing is also closer to how professional standards are written, so it reads as informed.
Study Tips for PSY-335
- Make flashcards pairing each concept with a short example.
- Practice evaluating a published test with the table above.
- Review correlation basics before reliability and validity.
- Always state who a test is suitable for.
- Note the professional standards your course cites.
- Use library databases for reviews of well-known tests.
