The 200-word examination instruction list
CLEP Human Growth and Development asks you to connect behaviour and evidence to development across the lifespan. Identify what changed, when it changed and how the researchers measured it before choosing a theory or conclusion.

What CLEP Human Growth and Development requires
| Exam component | Format and scope |
|---|---|
| Exam format | Approximately 90 questions in 90 minutes, including some unscored pretest items. |
| Scope | Physical, cognitive and social development across infancy, childhood, adolescence, adulthood and ageing. |
| Approach | Apply developmental theories and research methods to scenarios. College Board identifies DSM-5 terminology for questions involving diagnostic classification. |
CLEP is a U.S.-based college-credit examination programme. The receiving institution decides which exams and scores it accepts and how credit applies. Candidates outside the United States should check testing options with their test centre and acceptance with their institution.
Read the task before choosing an answer
When comparing ages, check whether the study followed the same people or compared groups born at different times. In a developmental example, choose the concept by the behaviour shown rather than relying on age alone.
Worked examples for common instructions
Identify a study design
Prompt. Researchers assess the same children at ages five, seven and nine. Name the design.
Answer. This is a longitudinal design because the same participants are measured repeatedly.
Distinguish assimilation and accommodation
Prompt. A child calls a zebra a horse, then learns to distinguish the two categories. What happens at each step?
Answer. The child first assimilates the zebra into an existing horse category. Revising the category to handle the distinction illustrates accommodation.
Recognise conservation
Prompt. A child says the amount of water stays the same after it moves from a wide glass to a narrow one. What is demonstrated?
Answer. Conservation of liquid quantity. The child judges the amount as unchanged despite its different appearance.
Identify a possible cohort effect
Prompt. At one point in time, older and younger adults report different use of a communication tool. What other explanation should be considered?
Answer. Their birth cohorts may have had different access to the technology or different work routines. A cross-sectional comparison alone cannot separate age from cohort.
Use the Fencing Method to build an answer
Start with one accurate response. Add the specific evidence or detail that makes it fit. Explain the connection, then apply the same reasoning to a new example.
Start. The design is longitudinal.
Add context. Researchers followed the same children from age five to age nine.
Add reasoning. Repeated observations allow the researchers to measure change within individuals. Participant loss could affect which trajectories remain observable.
Transfer. Change the study to compare different children at one time and explain how the inference changes.
Practise with the 200 terms
Choose two study designs and describe the evidence each can produce. Then take one developmental example and identify the behaviour that supports the interpretation.
Frequently asked questions
What is the first check in an age comparison?
Check how the groups were formed and whether the same people were measured more than once. Then ask which explanations the design can distinguish.
