Abstract
The goal of preschool education is to support children’s cognitive, physical, and socio-emotional development, providing a safe and nurturing environment for young children to learn and interact with their peers. However, estimates indicate that 250 million children (43%) younger than 5 years in low- and middle-income countries are at risk of not reaching their developmental potential due, in part, due to inadequate and inequitable access to preschools. In Ecuador, 60% of the children aged 3 to 4 years old remained unenrolled in 2020-21; numbers further declined after the covid-19 pandemic, with only 27% of 3- and 4-year-old children being provided with early childhood education services among rural and vulnerable populations. Recognising the lack of access to public preschools and additionally the lack of motivation among parents to send their child to preschools, the Ecuadorian Ministry of Education (MoE) launched a programme to provide regular home visits to ‘vulnerable’ families in 2018. In our study we collaborate with the MoE to improve the quality of this programme through professional development, technology-aided monitoring, and support for both teachers and parents. The evaluation will test if these programme improvements lead to an increase in child development outcomes using a cluster randomised control trial.

Other child development impacts: Motor skills using IDELA, Socio-emotional development using IDELA and parent-reported SDQ, Social preferences, Mental health/psychological state (self-portrait); Intervention take-up: participation in training sessions by teachers, tracking usage of the digital MIS by teachers and supervisors; Pathways to impact: teachers' knowledge, and professional and personal well-being, caregivers' self-efficacy, interaction with the child, and home learning environment.
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
Randomization will occur in the 48 districts of the Sierra regime. 48 districts have been purposively sampled (out of 61 districts). A total of 10 districts were excluded from the evaluation as they were newly created districts by 2022; 1 district in Sierra regime was found to be non-operational using the enrolment register for September 2022; 2 districts were found to have overlap between Sierra and Costa. The 48 study districts will be stratified by their size in terms of number of teachers per district. After stratification, equal number of districts will be assigned to 2 arms (Treatment=improved programme and Control=standard programme).
