Abstract
Learning to read is the most important outcome of primary education. However, despite substantial improvements in primary school enrolment, most students in low- and middle-income countries (LMICs) fail to learn to read by age 10. We report reading assessment data from over half a million pupils from 48 LMICs tested primarily in a language of instruction and show that these pupils are failing to acquire the most basic skills that contribute to reading comprehension. Pupils in LMICs across the first three instructional years are not acquiring the ability to decode printed words fluently and, in most cases, are failing to master the names and sounds associated with letters. Moreover, performance gaps against benchmarks widen with each instructional year. Literacy goals in LMICs will be reached only by ensuring focus on decoding skills in early-grade readers. Effective literacy instruction will require rigorous systematic phonics programmes and assessments suitable for LMIC contexts.
