This dataset includes data from 191 children and caregivers in the Nuwara Eliya province of Sri Lanka in June 2017. The data were collected as the baseline of a quasi-experimental impact evaluation examining the effectiveness of a preschool program for children living on tea plantations. The average age of children was four years.
IDELA Domains and Equity
Average learning and development scores in IDELA domains
On average, children scored 29% correct on the IDELA assessment.
Distribution of Total IDELA scores
Distribution of children’s ages
Children in the sample were three to five years old, with an average age of four years.
Average IDELA scores by child’s age
Age was significantly associated with IDELA scores, and on average, one additional year was associated with an additional 11 percentage points correct in overall IDELA score.
Distribution of children’s gender
54% of children in the sample were female. We observe no significant differences in IDELA scores by gender.
Home Learning Activities
Caregivers are asked about the types of learning activities they engaged in with their children in the past week. For example, caregivers are asked questions about whether they read stories to their child, taught letters or numbers, and/or sang songs with their child. Home learning activities provide stimulation which can help children reach their full developmental potential.
How many types of learning activities did caregivers engage in with children in the last week?
The majority of caregivers reported engaging in more than four types of learning activities with their children.
Do children who engage in more types of learning activities have stronger early learning and development?
Learning Materials in the Home
Caregivers are asked about the types of reading materials and toys they have in the home. For example, caregivers are asked if they have storybooks, puzzles, and/or toys that children can practice counting with. Toys and reading material provide a stimulating environment for children to explore, which can help boost early learning and development.
How many types of reading materials and toys do children have at home?
The majority of caregivers reported owning at least 4 types of reading materials or toys.
Do children with more types of learning materials have stronger early learning and development?
The home learning environment was significantly positively associated with overall IDELA score. An additional reading material or toy in the home was associated with a one percentage point higher Total IDELA score.
Caregivers are asked about the types of possessions that they own. The exact types of possessions asked about is contextual. For example, caregivers may be asked if they have a mobile phone, a bicycle, and/or electricity in the home. While not directly impacting early learning and development, children from wealthier families often have more opportunities.
How many types of possessions do families own?
On average, 59% of caregivers reported owning at least four types of common household possessions, and 41% owned one to three possessions. This measurement or wealth was not significantly associated with overall IDELA score.
