Our Impact
Data-driven evidence of how Zazi iZandi is transforming early literacy outcomes in the Eastern Cape.
Measuring What Matters
Four core metrics tracking real literacy gains for Grade 1 learners — from baseline to endline.
Letter Knowledge
+179%Grade 1 learners nearly tripled their letter-sound fluency over the course of the programme.
Hitting Benchmark
4xThe proportion of Grade 1 learners meeting the reading benchmark quadrupled from baseline to endline.
Zero-Letter Knowledge
-95%Nearly every child who started knowing zero letter sounds gained measurable literacy by end of year.
Word Reading
+68%Grade 1 learners improved their connected-text reading fluency significantly over the intervention period.
Exceeding National Benchmarks
Zazi iZandi learners consistently outperform national averages in Foundation Phase reading assessments.
Doubling the Number of Children Hitting Benchmark
In 6 months, Zazi iZandi doubles the number of children hitting the Grade 1 benchmark of 40 letters correct per minute. Research by Nik Spaull indicates this is highly correlated with becoming a future reader in Grades 3 & 4.
Building Foundations from Age 3
Zazi iZandi is effective with 3–5 year old children too — not just Grade R and Grade 1. Early intervention builds the letter-sound knowledge that unlocks reading.
ECD Letter Knowledge Growth
Children aged 3–5 in the Zazi iZandi programme show extraordinary gains in letter-sound knowledge, growing from near-zero to over 22 letters correct per minute — proving that structured early literacy intervention works well before formal schooling begins.

Grade R Pilot Results
Placeholder — describe the 6-week Grade R pilot results showing letter sounds known more than doubling from beginning to end of the intervention.

ECD Centres: Assessment Performance Over Time
ECD centres showed improvement of 14.9 letters from midline to endline, with children progressing from near-zero letter knowledge to over 22 letters correct.

ECD: Eliminating Zero Letter Knowledge
Placeholder — describe how the proportion of ECD children with zero letter knowledge was dramatically reduced through the intervention.
