Parent-Led School Readiness Trial Targets a Gap That Starts Before Primary School
Young children with neurodevelopmental delays and disabilities are still too often left at the edge of early education systems, even before formal schooling begins. The EN-REACH trial was designed to test whether a structured parent group intervention can improve school readiness for children aged 4 to 6 years in Bangladesh, Nepal, and Tanzania, including children who face developmental and functional barriers to learning. The study is built around a simple but consequential premise: if families receive practical coaching early enough, the transition from home to preschool and early primary education may become more accessible, more inclusive, and more realistic.
This is not a narrow classroom experiment. It is a cluster randomized controlled trial that treats school readiness as both a developmental and systems issue, with the home, the caregiver, and the local service environment all part of the intervention logic.
Three Countries, One Intervention, and a Design Built Around Real-World Delivery
EN-REACH uses a cluster randomized design with at least 150 clusters across the three countries. Geographic information systems will define roughly 50 clusters in each setting, and each cluster will contain about 10 parent-child dyads. Half of the clusters will be assigned to the intervention arm and half to control. The study plans to enroll approximately 500 participants from the EN-SMILING cohort at each site, linking the trial to an earlier observational platform and extending that work into an interventional phase.
The intervention itself is delivered by trained parent-teacher facilitator pairs. That delivery model matters because it is intended to be workable in ordinary community settings rather than dependent on highly specialized staff. Parent-led group sessions can be adapted around local routines, cultural expectations, and practical barriers such as transportation, caregiving burden, and limited access to specialized developmental services. In settings where disability inclusion is still uneven, the ability to deliver coaching through community-facing facilitators may determine whether a program remains a research exercise or becomes something health and education systems can actually absorb.
One sentence captures the central clinical and policy pressure point: the intervention is meant to move children from home-based care into early learning with fewer exclusions.
School Readiness as the Primary Endpoint
The primary endpoint is school readiness, measured with the Measuring Early Learning Quality and Outcomes tool. That choice signals a focus on functional preparedness rather than a narrow diagnostic lens. School readiness is shaped by multiple dimensions at once: cognition, language, behavior, attention, motor skills, sensory function, and the child’s ability to participate in a learning environment. In children with developmental delays or disabilities, these domains do not move in isolation. A child with reduced hearing, for example, may struggle with language acquisition and classroom engagement long before any formal academic test is attempted. A child with motor impairment may face barriers to participation that are mistaken for low readiness when the real issue is environmental fit.
Secondary outcomes widen the lens further. Investigators will assess Intelligence Quotient, child functioning, growth, and visual and hearing status. Those measures matter because educational readiness in early childhood is inseparable from health status. Hearing loss, visual impairment, undernutrition, and impaired global functioning can all suppress a child’s ability to engage with play-based learning and structured instruction. By measuring these domains alongside school readiness, the trial avoids treating learning as if it were disconnected from the body.
Why the Embedded Process Evaluation May Be as Important as the Outcome Data
The trial includes a process evaluation using the RE-AIM framework: Reach, Effectiveness, Adoption, Implementation, and Maintenance. That framework is especially relevant for a disability-inclusive intervention because efficacy alone does not answer the questions that determine scale. A program can improve readiness in a controlled setting and still fail if families do not attend sessions, facilitators cannot deliver the material consistently, or local institutions do not adopt the model after the study ends.
Quantitative data on coverage and quality of care will be paired with qualitative input from children, caregivers, facilitators, and stakeholders. That mixed-methods approach can expose where the intervention is working as intended and where it is being diluted by logistics, social norms, or health system constraints. In practice, the most informative data may come from the friction points: how families experience the group format, whether caregivers find the advice usable, whether facilitators can maintain fidelity, and whether the content fits the realities of children with different developmental profiles.
The protocol is explicit about the program’s intent to support co-designed, disability-inclusive school readiness. Co-design is more than a slogan in this setting. If families and local providers help shape the intervention, the content is more likely to reflect real caregiving practices, communication barriers, and early learning opportunities that exist in homes rather than in theoretical manuals.
From Developmental Equity to Policy-Relevant Evidence
The investigators frame the trial as a bridge between home life and early primary education, with potential relevance far beyond the enrolled cohort. That broader ambition is credible because the intervention sits at the intersection of child development, education access, and disability inclusion. In countries where early education systems already face pressure from uneven access and limited specialist resources, a parent-based model could offer a lower-intensity route to broader reach if the trial shows benefit and feasibility.
There is also a public health logic behind the work. Early childhood is a period of rapid neurodevelopment, and delays that go unaddressed can compound over time into poorer participation, lower attainment, and deeper exclusion. A program that supports readiness before school entry may prevent some of that downstream loss, especially for children whose developmental needs have not been identified or accommodated. For health and education systems, the question is not only whether the intervention improves scores on a readiness tool, but whether it can be delivered consistently enough to matter at population level.
Registration, Timing, and the Remaining Questions
The trial was retrospectively registered on ClinicalTrials.gov on 29 February 2024 under NCT06334627. Because this is a protocol, no efficacy conclusions are available yet, and the key unanswered questions remain practical: how large the effect on school readiness will be, whether the program works similarly across Bangladesh, Nepal, and Tanzania, and how well the intervention can be maintained once research staff are no longer driving delivery.
For children with disabilities, those questions carry special weight. A readiness program that works only for families with easier access to services would miss the population most likely to be excluded from early learning. EN-REACH is built to test whether a parent group model can reach that gap without leaving disability inclusion behind.
