Children’s Health & Wellbeing Matrix™

This matrix compares age-appropriate opportunities for children to interact with daylight, fresh air, vegetation, natural surfaces, water, wildlife and outdoor environments through everyday family, educational and recreational activities.

Purpose

The Children’s Health & Wellbeing Matrix™ provides a structured framework for identifying practical and progressive opportunities for environmental interaction throughout childhood. It supports families, carers and educators in comparing settings according to environmental richness, accessibility and the level of adult support required.

Scope

This matrix applies to children participating in ordinary home, neighbourhood, school, recreational and natural-environment activities. It considers environmental opportunities rather than academic performance, parenting quality, physical ability, family income or access to specialised programmes.

Standardised conditions

Unless otherwise stated, classifications assume:

• age-appropriate participation
• suitable adult supervision where required
• lawful access to the environment
• ordinary weather conditions
• activities suited to the child’s capabilities
• appropriate clothing, footwear and protective measures
• no acute illness or emergency conditions

The practical suitability of an environment may vary according to age, development, mobility, sensory needs, experience, weather, family circumstances and the availability of responsible supervision without changing the underlying environmental classification.

Important methodological boundary

This matrix does not rank children, families, schools or parenting approaches. A higher environmental class does not mean an activity is automatically more appropriate for every child. Classification reflects the richness of environmental interaction, while age suitability, accessibility, supervision and individual needs must be assessed separately.

Children’s Health & Wellbeing Matrix™

Children’s environments are assessed through separate measures of environmental quality, interaction opportunity and the level of adult support commonly required. A richer environment is not automatically the most suitable choice for every child or every stage of development.

Children’s environment Typical family, educational or recreational setting Environmental class Quality of environmental interaction Interaction opportunity Relative opportunity for active and sensory engagement Adult support Typical level of supervision or assistance required Interpretation How the setting may support age-appropriate participation
Windowless indoor activity space An enclosed setting with artificial lighting, controlled air and no direct access to natural views, vegetation or outdoor conditions. A Very limited Low Minimal direct environmental engagement Routine Ordinary age-appropriate supervision May support indoor learning or play but provides little direct environmental interaction. Nature-themed decoration or screens do not replace access to daylight, fresh air or living environments.
Indoor room with daylight and natural views A home, classroom or activity room with useful daylight and views of trees, sky, gardens or changing outdoor conditions. B Limited Moderate Useful visual and daylight contact Routine Ordinary supervision Provides a practical starting point where outdoor access is limited. Direct contact with air, vegetation, soil and weather remains restricted.
Balcony or terrace A small outdoor area providing daylight, fresh air, open sky and limited opportunities for planting, observation or quiet activity. C Moderate Moderate Convenient short-form outdoor interaction Close Direct supervision usually required Useful for brief outdoor contact, container gardening and observation. Suitability depends on secure barriers, surface conditions and the child’s age.
Private backyard or garden A familiar outdoor space with vegetation, natural light, open air and opportunities for free play, gardening and observation. C Moderate High Strong everyday interaction opportunity Variable Depends on age, layout and activity Combines familiarity with direct outdoor access. Mature planting, natural surfaces and varied activities may strengthen engagement without automatically changing the environmental class.
Schoolyard with limited planting A predominantly paved or structured outdoor area with open sky, some shade and scattered vegetation. B Limited Moderate Regular outdoor activity with limited natural variety Structured School or educator supervision Provides routine outdoor time but may remain dominated by hard surfaces, buildings and organised activity. Outdoor access alone does not establish a high environmental class.
Nature-rich schoolyard or sensory garden An educational outdoor area with diverse planting, shade, natural materials, garden beds and spaces for observation or quiet activity. C Moderate High Varied educational and sensory engagement Structured Educator guidance appropriate to activities Can support repeated, familiar environmental interaction during the school week. Managed design and limited scale generally keep it within Class C.
Local playground within an urban park A managed play area surrounded by lawns, established trees, shade and short walking routes within an urban setting. C Moderate High Accessible play and outdoor movement Close to variable Depends on age and playground design Offers practical outdoor activity and some contact with mature vegetation. Play equipment alone does not increase environmental classification.
Community garden A shared growing environment with soil, plants, seasonal change, insects and opportunities for guided participation. C Moderate High Direct, practical interaction with living systems Guided Adult instruction commonly required Provides meaningful hands-on environmental participation despite its usually small and managed setting. Tools, plants and shared areas require suitable guidance.
Botanical garden or large landscaped garden A managed public landscape with diverse plants, mature trees, shade, paths and extended opportunities for observation and walking. D High Very high Rich visual, sensory and educational opportunity Active Supervision appropriate to age and venue Provides sustained access to diverse vegetation in a structured setting. Institutional prestige, collection rarity or garden size alone do not justify Class D.
Riverside or lakeside park A freshwater environment combining water, vegetation, open views, wildlife and continuous outdoor routes. D High Very high Strong multisensory environmental engagement Close Direct waterside supervision required May provide rich environmental interaction through water, birds, plants and movement. Water hazards remain separate from the environmental grade.
Accessible beach or sheltered coastline An open coastal environment with sand, water, sea air, broad sky, natural sound and extensive opportunities for movement and observation. D High Very high Rich tactile, sensory and movement opportunity Close Active supervision essential near water Offers diverse environmental interaction, but suitability varies with surf, weather, heat and the child’s experience. Water risk does not increase the environmental class.
Forest or mature woodland A sustained natural setting with tree canopy, layered vegetation, natural surfaces, wildlife signs and reduced urban disturbance. D High Very high Strong immersive exploration opportunity Active Support depends on age, route and experience Provides sustained environmental variety and opportunities for observation, movement and imaginative play. Remoteness or route difficulty does not increase classification.
Exceptional accessible multi-habitat nature reserve An unusually rich setting combining mature woodland, water, open landscape, biodiversity, varied natural surfaces and long connected routes. E Exceptional Exceptional Maximum environmental interaction opportunity in this framework Planned Supervision and preparation matched to the child Suitable as a planned family or educational experience where routes and facilities match the child’s needs. Class E reflects environmental richness and continuity, not remoteness, difficulty, danger or prestige.
Class A Very limited direct interaction with daylight, fresh air, vegetation, natural surfaces or changing outdoor conditions.
Class B Limited environmental interaction through daylight, outdoor time or minor contact with natural features.
Class C Moderate interaction through accessible outdoor space, vegetation, soil, gardening, play or managed nature-rich settings.
Class D High interaction through mature vegetation, water, diverse habitats, sustained routes or meaningful separation from built surroundings.
Class E An exceptionally rich, continuous, accessible and diverse multi-habitat environment that clearly exceeds ordinary Class D settings.

How the Children’s Matrix is classified

The environmental class measures the richness of the setting. Interaction opportunity considers the range of age-appropriate sensory, practical and movement experiences available. Adult support is recorded separately because the need for supervision does not increase or reduce environmental quality.

  • Natural daylight
  • Fresh-air exposure
  • Vegetation diversity
  • Natural ground and tactile surfaces
  • Water and natural sound
  • Wildlife observation
  • Open space and movement
  • Shade and thermal comfort
  • Environmental continuity
  • Opportunities for gardening or practical participation
  • Quiet observation and imaginative play
  • Accessibility for different ages and abilities
  • Familiarity and frequency of use
  • Required adult support
  • Distance and practical access
  • Separation from traffic and built disturbance

A highly supervised setting may still provide exceptional environmental interaction. Conversely, an easily supervised indoor or paved setting may remain Class A or B. Supervision and suitability are therefore not used as environmental grading bonuses or penalties.

Quality-assurance review: Every Class D and E entry was challenged before publication. Nature-rich schoolyards, community gardens and urban playgrounds remain Class C because they provide useful but managed and comparatively limited environmental interaction. Botanical gardens, freshwater parks, beaches and forests reach Class D where mature natural features and sustained access are present. Class E is restricted to an unusually rich, accessible multi-habitat environment that clearly exceeds those settings. Danger, remoteness, difficulty, expense and prestige do not increase classification.

How to read the Children’s Matrix

The matrix separates environmental quality, interaction opportunity and the level of adult support commonly required. These measures should be considered together rather than treated as interchangeable ratings.

Read the environmental class first

The A–E class describes the richness and continuity of the environment itself. It does not change according to the child’s age, ability, confidence or level of supervision.

Then consider interaction opportunity

Interaction opportunity reflects the range of age-appropriate sensory, movement, observation and practical activities available within the setting.

Adult support remains separate

Some environments require closer supervision or more preparation than others. This affects suitability and access, but it does not raise or lower the environmental class.

Suitability is individual

The most environmentally rich setting is not automatically the best choice for every child. Age, mobility, sensory needs, confidence, weather and familiarity must be considered separately.

Environmental class

Measures daylight, fresh air, vegetation, water, natural surfaces, habitat diversity and separation from built disturbance.

Interaction opportunity

Considers movement, observation, touch, gardening, imaginative play, wildlife awareness and practical participation.

Adult support

Describes the typical level of supervision, guidance, planning or assistance needed for age-appropriate participation.

Class A: Very limited Little or no direct interaction with daylight, fresh air, vegetation, natural surfaces or changing outdoor conditions.
Class B: Limited Some daylight, outdoor time or minor contact with natural features is present, but the setting remains substantially built or controlled.
Class C: Moderate Accessible outdoor space, vegetation, gardening, soil, play or managed nature-rich settings provide a useful but incomplete environmental range.
Class D: High Mature vegetation, water, diverse habitats, sustained routes or meaningful separation from built surroundings provide strong environmental interaction.
Class E: Exceptional An unusually rich, continuous, accessible and diverse multi-habitat environment clearly exceeds ordinary Class D settings.

Factors affecting interpretation

The most useful setting is one that combines meaningful environmental interaction with realistic access, suitable support and the child’s individual needs. A familiar Class C environment used regularly may be more practical than a distant Class E setting used rarely.

  • Environmental class
  • Interaction opportunity
  • Child’s age and development
  • Mobility and accessibility
  • Sensory needs
  • Familiarity with the setting
  • Adult supervision
  • Available time
  • Travel requirements
  • Weather and temperature
  • Shade and shelter
  • Water proximity
  • Traffic separation
  • Natural surfaces
  • Opportunities for play and exploration
  • Quiet observation areas
  • Frequency of realistic use
  • Family and educational circumstances

Danger, remoteness, physical difficulty, expense and prestige do not increase environmental value. They may instead reduce suitability or access for a particular child.

Suggested progression

Progression should begin with familiar and practical environments, then expand toward richer settings as confidence, experience, mobility and available adult support allow. No child needs to advance through every stage.

Begin with daylight and natural views

Use a bright indoor area with views of trees, gardens, sky or changing weather when direct outdoor access is limited.

Add brief outdoor contact

Use a secure balcony, terrace, courtyard or doorway for short periods of fresh air, observation and weather awareness.

Use a familiar backyard or garden

Introduce free play, quiet sitting, simple gardening or observation in a familiar outdoor environment.

Explore a local playground or park

Choose an accessible setting with shade, vegetation and suitable space for movement while maintaining support appropriate to the child.

Add practical nature participation

Use a community garden, school garden or home planting activity to introduce soil, plants, seasons and living systems.

Visit a botanical or landscaped garden

Progress to a larger managed environment with mature trees, diverse plants, walking routes and opportunities for observation.

Introduce water environments carefully

Use a riverside, lakeside or sheltered coastal environment with supervision appropriate to the child and the setting.

Explore mature woodland

Use accessible forest or woodland paths for observation, movement and imaginative play as experience and confidence increase.

Plan richer multi-habitat visits

Use nature reserves or national parks where routes, facilities, duration and support match the child’s needs.

Build a regular personal pattern

Combine everyday local access with occasional visits to richer environments rather than relying only on infrequent major outings.

The best environment is one the child can use meaningfully

Environmental richness matters, but age-appropriate access, familiarity, support and regular use matter too. Children can begin with daylight, fresh air and nearby vegetation, then progress toward richer natural environments as their needs, confidence and circumstances allow.
