Early Childhood Development in Tonga: Baseline Results from the Tongan Early Human Capability Index

Core Content

This report presents the baseline results of the Tongan Early Human Capability Index (TeHCI), a study conducted by the World Bank in collaboration with the Tongan Ministry of Education and Training. The study is part of the Pacific Early Age Readiness and Learning (PEARL) Programme, which aims to improve early childhood development (ECD) in the Pacific Islands. The report highlights the importance of measuring ECD to inform policy and support the development of child-friendly programs.

Main Viewpoints

• Early Childhood Development (ECD) is defined as the holistic development of children from conception to about eight years, encompassing physical, cognitive, social, and emotional growth.
• The TeHCI measures children's capabilities rather than focusing on developmental delays or pathologies, offering a more comprehensive and positive view of child development.
• The study found that girls outperform boys in most developmental domains, with the exception of approaches to learning, a trend consistent with global literature.
• Mother's educational background significantly influences child development, as higher-educated mothers are more likely to engage in stimulating home activities and provide early education opportunities.
• There is little or no difference in development outcomes across islands, except for physical development, which suggests that geographic disparities are not as pronounced as expected.
• Home-based stimulation such as reading, singing, and playing with children is positively associated with better developmental outcomes, especially in literacy and numeracy.
• Preschool participation has a positive impact on development, although its effect is less than that of home stimulation.
• Over half of Tonga's children start school without any prior exposure to early education programs, highlighting the need for improved access to ECD services.
• Geographic mapping of the TeHCI results helps communities understand their children's developmental status relative to others and facilitates targeted interventions.

Key Information

Overview of Tonga

• Tonga is an upper-middle-income economy with a population of over 100,000.
• The country is composed of five main island groups: Tongatapu, Vava'u, 'Eua, Ha'apai, and the Niuas.
• The capital, Nuku'alofa, is located on Tongatapu and is the main commercial and harbor center.
• High net migration exists, with over 66% of the population living abroad.
• Absolute poverty is low, but hardship (lack of cash for basic goods) is more widespread.

PEARL Programme

• Funded by the Global Partnership for Education and implemented by the World Bank.
• Aims to support Pacific Island countries in building capacity for evidence-based ECD programs.
• Focuses on two key areas: early childhood education and community-based development.

TeHCI Development

• The index was developed through a consultation process involving key stakeholders in Tonga.
• It assesses children in seven developmental domains:
  • Physical health
  • Verbal communication
  • Cultural identity and spirituality
  • Social and emotional wellbeing
  • Perseverance and approaches to learning
  • Numeracy and concepts
  • Literacy (reading and writing)
• The index was tested across all three- to five-year-olds in Tonga through a country-wide census.

Findings

• Girls outperform boys in most domains.
• Mother's education level is strongly linked to child development outcomes.
• Home-based stimulation (e.g., reading, playing) has a greater impact on development than preschool attendance.
• Preschool participation still positively affects development, especially in literacy and numeracy.
• Geographic disparities are minimal, except for physical development.
• Over 50% of children start school without any early education experience.

Conclusion

The TeHCI provides a valuable tool for monitoring early childhood development in Tonga and has demonstrated the importance of home-based stimulation and early education in shaping children's future. The study underscores the need for improved access to ECD services, especially in remote areas, and highlights the role of local leadership and community engagement in driving positive change. The results also serve as a model for other Pacific Island countries to follow in their efforts to improve early childhood outcomes.

Future Use

• The TeHCI can be used to design targeted interventions and improve ECD services.
• It supports policy planning and strategic investments in early education.
• The geographic mapping of results helps in resource allocation and community awareness.
• The PEARL programme aims to scale and sustain these initiatives across the Pacific region.

Key Contributions

• The World Bank and Tonga's Ministry of Education and Training collaborated to develop and implement the TeHCI.
• The study involved community engagement, stakeholder consultations, and technical support from various experts and institutions.
• The data dissemination process included public meetings to encourage discussion and action at the local level.
