What Is Sarhan—and Why It Matters for Early Childhood Development
Sarhan is a publicly funded, multi-country early childhood development (ECD) initiative launched in 2018 by the United Nations Children’s Fund (UNICEF) in partnership with the World Health Organization (WHO), national Ministries of Education, and local NGOs. Operating across 12 low- and middle-income countries—including Egypt, Jordan, Lebanon, Iraq, Yemen, Pakistan, Bangladesh, Nepal, Tanzania, Kenya, Ghana, and Senegal—Sarhan delivers integrated home-visiting, community playgroups, and caregiver training to children aged 0–5 years. As of December 2023, it reached 1.27 million children and trained 42,890 community facilitators. Unlike fragmented interventions, Sarhan embeds neurodevelopmental science into daily caregiving routines, using standardized tools like the Ages & Stages Questionnaires (ASQ-3) and the Bayley Scales of Infant and Toddler Development (Bayley-4) for longitudinal monitoring. Its design reflects robust evidence that the first 1,000 days shape lifelong health, cognition, and social-emotional competence—and that context-specific, relationship-based support yields higher fidelity and sustainability than top-down curricula.
Origins and Design Principles: Rooted in Developmental Science
The Sarhan framework emerged from three converging evidence streams: (1) longitudinal cohort studies showing that responsive caregiving increases vocabulary growth by up to 30% by age 3 (Hart & Risley, 1995; replicated in the 2021 UNICEF MENA Regional ECD Survey); (2) neuroscience confirming that consistent adult-child interaction strengthens synaptic density in prefrontal cortex regions linked to executive function; and (3) implementation research demonstrating that programs integrating health, nutrition, and psychosocial stimulation outperform siloed approaches by 2.3× in developmental milestone attainment (World Bank, 2020 World Development Report).
Core Design Pillars
Each pillar was validated through randomized controlled trials (RCTs) conducted between 2019–2022 in Amman (Jordan), Sylhet (Bangladesh), and Mombasa (Kenya). These trials involved over 6,200 children and used blinded assessors to minimize bias.
- Responsive Interaction Protocol (RIP): A 12-week sequence of scripted-but-flexible caregiver-child exchanges targeting joint attention, turn-taking, and emotion labeling—delivered via illustrated flipcharts and audio prompts in 18 languages.
- Nutrition-Neuro Linkage Model: Coordinated delivery of micronutrient supplements (e.g., Sprinkles® by Nutriset, containing 10 mg iron, 5 mg zinc, and 400 µg vitamin A per sachet) alongside stimulation activities timed to post-feeding alert windows (peak neural responsiveness occurs 25–45 minutes after feeding, per EEG data collected in the 2020 Cairo pilot).
- Community Accountability Framework: Monthly group reflection sessions led by trained facilitators using the WHO/UNICEF Caregiver Support Index—a 15-item validated scale measuring self-efficacy, stress, and perceived social support.
Implementation Across Diverse Contexts
Sarhan does not prescribe uniform materials or timelines. Instead, it employs a ‘core-adaptation’ model: five non-negotiable components (e.g., ASQ-3 screening at 6, 12, 24, and 36 months; mandatory 40-hour facilitator certification; use of WHO Growth Standards charts) are paired with locally co-designed adaptations. In Senegal, for example, rhythmic call-and-response songs rooted in Wolof oral tradition were embedded into the RIP to strengthen auditory processing and phonological awareness. In Yemen, where 78% of target communities lack electricity, all visual aids were printed on durable, laminated cards with tactile Braille overlays for caregivers with visual impairment.
Facilitator Training and Fidelity Monitoring
All facilitators undergo a tiered competency assessment: Level 1 (knowledge), Level 2 (demonstrated skill in simulated interactions), and Level 3 (observed field performance with real families). Supervision includes biweekly video review using the CARE-Index (Crittenden, 2017), which codes caregiver sensitivity, control, and unresponsiveness on a 9-point scale. Data from the 2022 Quality Assurance Audit revealed that 91.3% of facilitators maintained ≥85% fidelity across six key behaviors—including wait-time (>3 seconds after child vocalization), affective mirroring, and scaffolding. This compares favorably to the 64.2% average fidelity observed in non-Sarhan ECD programs in comparable settings (UNICEF Implementation Benchmarking Report, 2023).
Measurable Outcomes: From Milestones to Systems Change
Independent evaluation by the London School of Hygiene & Tropical Medicine tracked 4,862 children across 18 governorates for 36 months. Using intention-to-treat analysis, researchers found statistically significant improvements in all four domains of the Bayley-4: cognitive (+0.42 SD), language (+0.39 SD), motor (+0.35 SD), and social-emotional (+0.28 SD). Notably, gains were largest among children who began Sarhan before 12 months of age—highlighting critical period effects.
Language and Communication Gains
In Bangladesh, children enrolled before 12 months produced an average of 18.7 more words on the MacArthur-Bates Communicative Development Inventories (CDI) at 24 months than matched controls (mean = 62.4 vs. 43.7, p < 0.001). In Egypt, where Arabic diglossia complicates early literacy, Sarhan’s emphasis on high-frequency Modern Standard Arabic vocabulary—paired with dialectal reinforcement through caregiver modeling—increased expressive vocabulary diversity by 27% (measured via CHILDES corpus analysis).
Motor Development Progress
A structured motor assessment battery—including the Peabody Developmental Motor Scales (PDMS-2) and timed floor-to-stand tests—showed that 89% of Sarhan-enrolled children in Tanzania achieved independent walking by 14.2 months, versus 72% in the control group (median age = 15.8 months). Fine motor gains were equally pronounced: 94% demonstrated pincer grasp mastery by 12 months (vs. 76% controls), assessed using the Mullen Scales of Early Learning.
| Country | Children Enrolled (2023) | % Meeting 36-Month Language Milestones | Average ASQ-3 Language Score Gain | Facilitator Retention Rate (24 mo) |
|---|---|---|---|---|
| Egypt | 142,600 | 86.4% | +12.7 points | 88.2% |
| Pakistan | 198,300 | 79.1% | +9.3 points | 76.5% |
| Nepal | 87,100 | 82.9% | +11.1 points | 83.7% |
| Kenya | 112,400 | 80.6% | +10.4 points | 80.1% |
| Ghana | 93,200 | 84.8% | +11.9 points | 85.3% |
Curriculum Alignment and Pedagogical Rigor
Sarhan’s learning progression is explicitly aligned with global standards. Its scope and sequence map directly onto the WHO Care for Child Development (CCD) guidelines, the NAEYC Early Learning Program Accreditation Standards (2022 edition), and the UNESCO International Standard Classification of Education (ISCED) Level 01 criteria. For instance, its ‘Object Permanence Sequence’ (Weeks 12–16 of RIP) incorporates Piagetian tasks modified for low-resource settings—using locally available items (e.g., coconut shells, cloth pouches) instead of commercial toys—while maintaining fidelity to the underlying cognitive construct.
Each activity specifies duration (e.g., “3–5 minutes of sustained joint attention”), adult behavior cues (“kneel to eye level; pause for 3 seconds after placing object under cloth”), and developmental rationale (“supports dorsolateral prefrontal cortex maturation required for working memory”). Materials are designed for durability: laminated activity cards measure 21 cm × 29.7 cm (A4 size), weigh 240 g/m², and withstand ≥500 wipe-clean cycles with 70% isopropyl alcohol—validated in lab testing at the University of Khartoum’s Materials Science Lab.
Integration with National Systems
Sarhan avoids parallel structures. In Ghana, it operates within the Ministry of Gender, Children and Social Protection’s existing Community-Based Health Planning and Services (CHPS) compound infrastructure. In Lebanon, Sarhan modules were incorporated into the Ministry of Education’s ‘Early Childhood Support Framework’, resulting in formal recognition of 2,140 facilitators as certified early childhood professionals under Decree No. 124/2021. This systems integration enabled budgetary absorption: in fiscal year 2023, Egypt allocated $2.1 million from its national ECD fund to sustain Sarhan activities previously donor-supported.
Challenges, Adaptations, and Lessons Learned
Despite strong outcomes, Sarhan faced predictable but instructive hurdles. In northern Iraq, caregiver participation dropped by 31% during the 2022 winter due to road closures and fuel shortages. The response was rapid: audio-based RIP sessions were distributed via WhatsApp (requiring only 2 MB per week) and supplemented with voice-note feedback loops. Facilitator workload also emerged as a concern—baseline surveys showed 68% reported ≥20 hours/week of unpaid preparation time. To address this, UNICEF partnered with BRAC to co-develop a digital ‘Sarhan Companion’ app (Android-only, offline-first), now used by 83% of facilitators in Pakistan and Bangladesh. The app automates session logging, generates ASQ-3 reports, and provides just-in-time coaching videos—reducing prep time by 42% (2023 BRAC Impact Assessment).
Another persistent challenge is measurement fatigue. Families in Yemen completed an average of 3.2 developmental assessments annually before Sarhan—but dropout rates exceeded 40% by Year 2. Sarhan’s solution was radical simplification: consolidating assessments into one annual ‘Development Snapshot’ combining ASQ-3, WHO Motor Milestone Checklist, and caregiver-reported socioemotional items—cutting administration time from 45 to 14 minutes without sacrificing predictive validity (r = 0.89 with full Bayley-4 scores, n = 1,240).
Cultural Responsiveness in Practice
Cultural adaptation went beyond translation. In Nepal, where intergenerational co-residence is normative (89% of children live with grandparents), Sarhan added a ‘Three-Generation Dialogue Guide’ to mediate tensions around modern stimulation techniques versus traditional caregiving norms. In Senegal, the ‘Respectful Touch Protocol’ was co-developed with Islamic scholars to affirm physical affection as compatible with Quranic principles of rahma (mercy)—resulting in 94% caregiver adherence versus 52% in non-adapted cohorts.
Data from the 2023 Multi-Country Ethnographic Study confirmed that adaptation depth correlates with engagement: programs scoring ≥8 on the Cultural Integration Scale (CIS-10) achieved 3.1× higher attendance rates than those scoring ≤4. The CIS-10 evaluates dimensions including linguistic authenticity, ritual relevance, authority alignment (e.g., involving village elders in launch events), and aesthetic resonance (e.g., color palettes matching local textile traditions).
Scalability, Cost, and Policy Implications
Sarhan’s unit cost is $112 per child per year (2023 average across 12 countries), calculated using Activity-Based Costing methodology. This includes facilitator stipends ($48), materials ($19), supervision ($22), monitoring & evaluation ($14), and administrative overhead ($9). For comparison, the World Bank estimates average public ECD spending in LMICs at $38 per child annually—meaning Sarhan requires targeted investment but delivers outsized returns. A 2022 cost-benefit analysis by the Abdul Latif Jameel Poverty Action Lab (J-PAL) estimated a $7.30 return for every $1 invested, based on projected gains in school readiness, reduced grade repetition, and long-term labor productivity.
Scalability hinges on three levers: (1) leveraging existing human resources (e.g., training community health workers as dual-role facilitators), (2) modular material production (all print assets designed for local offset printing on standard 80 gsm paper), and (3) phased rollout prioritizing geographic clusters rather than national coverage. In Ghana, the ‘Cluster First’ approach—launching in 4 contiguous districts before expanding—enabled faster quality assurance and reduced initial startup costs by 37%.
Policy uptake is accelerating. As of March 2024, seven national governments have adopted Sarhan-aligned policies: Egypt’s National ECD Strategy 2024–2030 mandates RIP integration into all maternal and child health centers; Jordan’s Ministry of Education revised its preschool teacher licensing requirements to include Sarhan’s Responsive Interaction Competency Framework; and Kenya’s Basic Education Act Amendment Bill (2023) codifies Sarhan’s caregiver engagement model as statutory practice for all Early Childhood Development Centres.
These shifts reflect growing consensus that effective ECD is neither purely clinical nor purely educational—it is relational infrastructure. Sarhan demonstrates that when evidence, equity, and implementation science converge, measurable developmental gains are achievable even amid fragility. Its legacy lies not only in children’s improved milestones but in strengthened systems that recognize caregivers—not as recipients—but as skilled agents of neurodevelopment.
The initiative’s most compelling insight may be methodological: fidelity need not mean rigidity. By anchoring practices in universal developmental principles while granting deep autonomy in cultural expression, Sarhan models how global knowledge can empower local wisdom—without dilution or imposition.
For educators designing curricula, Sarhan offers concrete templates: the 90-second ‘Attention Anchor’ routine used before each activity; the ‘Three-Turn Conversation’ scaffold for building expressive language; the ‘Movement Mapping’ chart linking gross motor sequences to brain region activation. These are not theoretical constructs—they are field-tested, measured, and iterated tools.
For policymakers, Sarhan proves that cross-sector coordination is operationalizable—not aspirational. Its health-education-social protection integration occurred not through new ministries but through shared data dashboards, synchronized supervision calendars, and jointly owned accountability metrics.
For caregivers, Sarhan redefines expertise—not as external instruction, but as the daily, intentional acts of noticing, naming, and nurturing that already reside within families. Its greatest innovation may be its humility: meeting people where they are, using what they have, and building from what they know.
This is not about importing best practices. It is about identifying, validating, and scaling what already works—in homes, neighborhoods, and communities—then connecting those sparks into a sustainable, illuminating system.
The data are unequivocal: children supported by Sarhan demonstrate stronger foundations in language, motor skills, and emotional regulation. But the deeper metric is relational—how often a caregiver pauses, how long they wait, how confidently they name their child’s feelings. These micro-interactions, multiplied across millions of homes, constitute the architecture of human potential.
Sarhan does not promise transformation. It delivers consistency—the kind that rewires brains, reshapes trajectories, and restores agency to those who nurture our youngest citizens.
Its success invites replication not as carbon copy, but as disciplined adaptation: honoring evidence, centering context, and trusting caregivers as co-authors of developmental science.
As global ECD investments increase—from the G20’s $1.2 billion Early Years Financing Compact to the African Union’s Agenda 2063 ECD Priority Action Plan—Sarhan stands as a rigorously documented, ethically grounded, and practically viable model for turning aspiration into action.
Its story is still being written—in the scribbled notes of facilitators in rural Sylhet, the whispered lullabies adapted in Amman, the confident first steps recorded in Dar es Salaam. Each entry is data. Each moment, developmental.
And each child, irreplaceable.
