Child learning statistics show a wide gap between being enrolled in school and mastering foundational skills. UNICEF reported that, in half of the countries it analyzed, only 30% of Grade 3 children had foundational reading skills and only 18% had foundational numeracy skills. U.S. and OECD studies add detail about early education, family learning activities, digital-device use, and the conditions associated with stronger early outcomes.

Foundational reading and numeracy
Foundational skills are the early abilities children need to continue learning: reading simple text, understanding meaning, working with basic numbers, and applying basic mathematical ideas. The UNICEF findings concern children attending Grade 3 in the countries included in its analysis, so they should not be read as a universal estimate for every country or every child.
According to UNICEF’s Are Children Really Learning? (2022), in half of the countries analyzed, 30% of children attending Grade 3 had foundational reading skills. In the same group of countries, 18% of Grade 3 children had foundational numeracy skills. These figures describe the share who reached the specified foundational level, not the percentage who were enrolled.
UNICEF also compared the expected time for learning with the average time suggested by the results. In the countries analyzed, most schoolchildren would need an average of 7 years to learn foundational reading skills that should have been grasped in 2 years. For foundational numeracy, most schoolchildren would need an average of 11 years to learn skills that should have been grasped in 2 years. The comparison is about learning time in the analyzed countries; it is not a forecast for an individual child.
| Indicator | Reported result | Scope and period |
|---|---|---|
| Grade 3 children with foundational reading skills | 30% in half of analyzed countries | UNICEF analysis, 2022 |
| Grade 3 children with foundational numeracy skills | 18% in half of analyzed countries | UNICEF analysis, 2022 |
| Average time for foundational reading | 7 years, versus 2 years expected | Countries analyzed by UNICEF |
| Average time for foundational numeracy | 11 years, versus 2 years expected | Countries analyzed by UNICEF |
These results place basic skill acquisition at the center of child learning. A child can spend years in school while still lacking the skills that later lessons assume. That distinction matters when interpreting enrollment figures: attendance and progression do not by themselves demonstrate mastery.
Learning disruption and school re-entry
The UNICEF DATA report Are Children Really Learning? (2022) described major interruptions during the COVID-19 pandemic. UNICEF estimated that 23 countries were still yet to fully open schools during the third year of the pandemic. Those 23 countries were home to around 405 million schoolchildren. Nearly 147 million children missed more than half of their in-person schooling over the prior two years, amounting to 2 trillion hours of lost learning.
The effects varied by country and by group. In South Africa, the number of out-of-school children tripled from 250,000 to 750,000 between March 2020 and July 2021. In Malawi, the dropout rate among girls in secondary education increased by 48% between 2020 and 2021. In Liberia, 43% of students reportedly did not return to the classroom when schools reopened. In Uganda, about 1 in 10 students at the primary and secondary levels did not report back to school at reopening.
The same UNICEF DATA source reported particularly severe learning conditions in some settings. In the Central African Republic, out-of-school children had no foundational reading skills in the UNICEF analysis. In Chad, half of all children aged 8–14 were out of school. These country-specific results should remain tied to their stated geography and the 2022 reporting context.
Wealth and access gaps
Learning opportunities are not distributed evenly. UNICEF DATA (2022) reported that children in the lowest wealth quintile had foundational reading skills 16 percentage points less often than children in the highest wealth quintile. For foundational numeracy, children in the lowest wealth quintile had the skill 9 percentage points less often than children in the highest wealth quintile.
A percentage-point difference compares two rates directly. It does not mean that the lower-wealth group had a result that was 16% lower in every interpretation. The UNICEF measure indicates a gap in the share of children reaching the foundational skill level, with wealth quintiles used to compare economic groups.
The access pattern also appears in early childhood education. In the OECD study Early Learning and Child Well-being in the United States (2020), 80% of U.S. five-year-olds had attended an early childhood education and care setting before starting school. Attendance was 73% among children in the lowest socio-economic quartile and 91% among children in the top socio-economic quartile. Those figures describe the U.S. study sample and the socio-economic groups used by that study.
Early childhood education in the United States
The OECD’s 2020 U.S. early-learning study measured several early conditions alongside children’s skills and well-being. In the study sample, 13% of children had parents reporting learning difficulties such as speech or language delay or intellectual disability. Also, 39% of five-year-olds had mothers who had completed higher education.
The study reported differences in assessments of expressive language. Seven percent of parents rated their child’s expressive language development as below average, while about 21% of educators rated children’s expressive language skills as below average. These are separate ratings by two respondent groups, so they should not be treated as two measurements of exactly the same assessment.
Five-year-olds who had ever attended ECEC had higher emergent literacy scores than children who had never attended. They also had higher emergent numeracy scores. The reported associations do not establish that attendance alone caused every difference; children and families entering different arrangements may also differ in other ways.
The study included more specific age-and-hours comparisons. Five-year-olds who had more than 20 hours per week of ECEC at age 1 had working memory scores 25 points higher than children who did not attend at that age. Five-year-olds who attended ECEC for less than 20 hours per week at age 4 had mental flexibility scores 16 points higher than children who did not attend at that age. Both comparisons apply to the U.S. study and its measured score scales.
The NCES/IES report What Do Parents Look for When Choosing an Early Childhood Care Arrangement? (2024), using the 2019 U.S. NHES survey, reported that 59% of children age 5 and under were in a care arrangement. Parents’ priorities varied by the child’s age: learning activities were rated as very important by 59% of parents for children under age 1, 64% for children ages 1–2, and 74% for children ages 3–5.
Family activities and early learning
Family activities provide another view of children’s learning environments. In the NCES/IES report The Growing Reading Gap (2021), 2019 data showed that 85% of U.S. 3- to 5-year-olds were read to by a family member three or more times in the prior week. In the same year, 87% were told a story by a family member at least once in the prior week, and 96% were taught letters, words, or numbers by a family member at least once in the prior week.
Library visits were less common: 37% of U.S. 3- to 5-year-olds visited a library with a family member at least once in the prior month. These measures use different time windows, so reading, storytelling, teaching, and library visits should not be ranked as if they were identical behaviors.
The OECD U.S. study (2020) also connected home reading frequency with measured outcomes. In the United States, children whose parents read to them most often had significantly higher emotion identification and emotion attribution scores than children read to less frequently. The finding concerns the study’s measured association and does not specify that a particular number of reading days guarantees a particular score.
The same OECD study reported that children whose parents were moderately or strongly involved in school activities had higher emergent literacy scores and higher emergent numeracy scores than children with less-involved parents. They also had higher prosocial behaviour scores, trust scores, and non-disruptive behaviour scores. These comparisons cover academic, social, and behavioral measures rather than one single definition of learning.
Reading, language, and digital-device use
The 2020 OECD study recorded how often U.S. parents read books to their five-year-olds. Seven percent read less than once a week, 20% read one or two days a week, 32% read 3–4 days a week, and 43% read 5–7 days a week. The categories describe the distribution reported for the United States; they are not a recommended schedule.
Digital-device use was also measured. In the United States, 49% of five-year-olds used a digital device such as a laptop, tablet, or smartphone every day. Across the three OECD countries in the study, 83% used a digital device at least once a week and 42% used one every day. The U.S. daily-use figure and the three-country figures have different geographic scopes.
U.S. preschool enrollment changed only slightly for some age groups. NCES Fast Facts: Preprimary education enrollment reports that the U.S. preschool enrollment rate for 3- to 4-year-olds rose from 48% in 2012 to 49% in 2019. For 5-year-olds, the rate was 86% in both 2012 and 2019. These are enrollment rates for the stated years, not measures of learning achievement.
Taken together, the figures point to several measurable parts of child learning: foundational skill mastery, time spent in early education, family reading and teaching, language development, and continuity of schooling. The sources use different populations, countries, years, and outcome measures, so each statistic is most useful when read with its original scope and measurement period.
