Understand the development of a child from one to five years
This subtopic covers the typical physical, intellectual, and social developmental milestones for children aged one to five years, alongside the critical role of play in fostering holistic growth. It equips learners with the skills to observe real children objectively, plan age-appropriate play activities targeting specific developmental areas, and evaluate their effectiveness. Practical application is central, enabling learners to translate theory into high-quality care and education practices in early years settings.

Quick Revision Summary (Key Takeaway)
Cambridge National in Child Development covers the physical, intellectual, emotional, and social development of children from birth to five years. It includes understanding developmental milestones, the role of play, and the responsibilities of practitioners in supporting children's growth.
Topic Overview
Child development is the study of how children grow and change from birth to five years. This period is critical as it lays the foundation for future health, learning, and wellbeing. The Cambridge National in Child Development covers the key areas of physical, intellectual, emotional, and social development, and how these are interconnected. You will learn about the expected milestones at different ages, the factors that influence development, and the importance of early experiences.
This topic is central to the qualification because it underpins all aspects of working with children. Whether you are considering a career in early years education, health visiting, or social work, understanding how children develop is essential. The course also emphasises the role of play and how practitioners can create environments that support learning and development. You will explore how to observe children effectively, plan activities, and work in partnership with families.
In the wider subject, this knowledge is applied in real-world settings. You will learn about the responsibilities of a child development practitioner, including safeguarding, promoting equality, and supporting children with additional needs. The skills you gain, such as observation and analysis, are not only vital for exams but also for practical work placements. By the end of this topic, you will have a solid foundation for further study or employment in the childcare sector.
Key Concepts
Core ideas you must understand for this topic
- →Developmental milestones: key skills and behaviours that most children can do by a certain age, e.g., walking by 12-15 months.
- →PIES: Physical, Intellectual, Emotional, Social development – the four main areas of development.
- →Holistic development: viewing the child as a whole, recognising that all areas of development are interconnected.
- →Observation: a key skill used to assess development, plan activities, and identify any concerns.
- →The role of play: play is essential for learning and development, and practitioners must provide a range of play opportunities.
Learning Objectives
What you need to know and understand
- Physical, intellectual and social developmental norms from one to five years, Stages and types of play and how play benefits development, Observe the development of a child aged one to five years, Plan and evaluate play activities for a child aged one to five years for a chosen area of development
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurate identification of key physical milestones between one and five years (e.g., walking independently by 18 months, hopping by 4 years).
- Credit given for clear explanation of the link between a specific type of play (e.g., sensory play) and a developmental domain (e.g., cognitive).
- Observation evidence must include objective, factual recording without interpretation, and be linked to a developmental norm.
- When evaluating a planned play activity, credit analysis of why the activity was or wasn't effective in promoting the chosen area of development, with suggestions for improvement.
Assessment Guidance
Guidance for achieving higher grades
- 💡When documenting observations, use the 'what, why, how' format: what you observed, why it links to a developmental norm, and how it supports the child's development.
- 💡Always reference the specific developmental area (physical, intellectual, social) when planning a play activity, and choose activities with clear, measurable developmental intentions.
- 💡Use correct terminology for play stages (solitary, parallel, associative, cooperative) and link them accurately to age ranges, e.g., associating parallel play with ages 2–3.
- 💡In evaluations, go beyond simply stating if the child enjoyed the activity; focus on evidence of progress towards the developmental goal and how the activity could be adapted.
- 💡Always use specific ages when describing milestones, e.g., 'by 6 months' rather than 'babies can sit up'. This shows precise knowledge.
- 💡When answering evaluation questions, use a balanced approach – give both strengths and limitations, and come to a justified conclusion.
- 💡Use the PIES framework to structure answers about development – it ensures you cover all areas and gain full marks.
Common Mistakes
Common errors to avoid in your coursework
- Confusing the typical age range for achieving milestones (e.g., assuming all children walk by 12 months or can skip by 3 years).
- Providing an observation that includes personal opinions or assumptions (e.g., 'The child was angry') rather than factual descriptions (e.g., 'The child frowned and pushed the toy away').
- Selecting a play activity that is mismatched to the child's age and stage (e.g., expecting a 2-year-old to share and take turns in a complex board game).
- Describing the play activity in detail but failing to evaluate its actual impact on the child's development, or making evaluation statements without evidence.
- Misconception: All children develop at the same rate. Correction: While there are typical milestones, each child is unique and may develop at different rates. Practitioners should be aware of 'normal' ranges but not overly concerned if a child is slightly behind.
- Misconception: Intellectual development only involves learning to read and write. Correction: Intellectual development includes thinking, problem-solving, memory, and language. For example, a baby exploring objects with their mouth is intellectual development.
- Misconception: Play is just for fun and not important. Correction: Play is crucial for all areas of development. It helps children learn social skills, physical coordination, and cognitive abilities. Practitioners should plan purposeful play activities.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on learning the developmental milestones for each age group (0-1, 1-2, 2-3, 3-5). Create flashcards or a timeline. Test yourself daily.
- 2Week 2: Study the factors affecting development (e.g., genetics, nutrition, environment). Make mind maps linking factors to PIES areas.
- 3Week 3: Practise observation techniques and how to plan activities. Do past paper questions on these topics.
- 4Week 4: Revise the role of play and how to support development. Use active recall to summarise key points from memory.
- 5Week 5: Take full practice papers under timed conditions. Review your answers against mark schemes.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions: Test recall of key facts, e.g., 'At what age do most babies start to sit up?' – Learn precise ages and definitions.
- 📋Short-answer questions: Require brief explanations, e.g., 'Give two factors that can affect development.' – Use bullet points and specific examples.
- 📋Extended writing questions (6-8 marks): Often ask to 'Explain' or 'Evaluate' a topic, e.g., 'Evaluate the importance of play.' – Structure with PEE (Point, Evidence, Explanation) and include a conclusion.
- 📋Practical-based questions: May describe a scenario and ask how a practitioner would respond, e.g., 'A child is not meeting milestones. What should the practitioner do?' – Apply knowledge of observation and referral.
Command Word Expectations (OCR)
What examiners look for when using specific command words in this specification
Give a detailed account of the features or characteristics of something. For example, 'Describe the physical development of a 2-year-old.' You should state the key milestones without explanation.
Give reasons or causes for something. For example, 'Explain how play supports intellectual development.' You must give a point and then elaborate on how or why it happens.
Make a judgement based on evidence. For example, 'Evaluate the use of observations in child development.' You must consider strengths and weaknesses and come to a conclusion.
