Zambia Records Major Gains in PISA 2025, But Inequality and Digital Use Remain Challenges
By Alain Kabinda | Lusaka
Zambia has recorded significant improvements in the 2025 Programme for International Student Assessment (PISA), with 15-year-olds posting major gains in Reading, Science and Mathematics compared to 2018.
The results, released internationally on Monday, show Zambia’s reading score rose from 275 points in 2018 to 325 points in 2025 — a 50-point jump. Science increased from 309 to 357 points, a gain of 48 points. Mathematics also improved from the country’s previous participation in PISA for Development.
For a country that has long ranked near the bottom of international education comparisons, the gains are being hailed as early proof that education reforms are working.
Speaking at the launch, Ministry of Education Permanent Secretary Dr. Kelvin Mambwe said the results must be used to guide policy, not filed away.
“It is an opportunity to learn from our own data rather than learning from social media critics,” he said.
Government has rolled out free education, recruited over 40,000 teachers, and increased investment in classrooms, school furniture, grants, school feeding and new schools.
According to PISA National Coordinator Dr. Shadreck Nkoya, more than 2.5 million additional children have entered school since free education began.
“Rather than seeing the quality of education go down, we have seen improvement. This is not common in education,” Dr. Nkoya said.
ECZ Executive Director Dr. Michael Chilala said the next step is to identify which interventions are driving results. Priority areas include school feeding, teacher recruitment, new learning modules from the Curriculum Development Centre, and catch-up programmes.
Dr. Chilala said this matches Zambia’s shift to competency-based education under the 2023 Curriculum Framework, aimed at producing critical thinkers who can adapt to technology and a changing economy.
OECD Data Manager Guillaume Bousquet noted positive attitudes among Zambian learners. Nearly 60% disagreed that intelligence is fixed, and Zambian students scored 10 percentage points above the OECD average in willingness to work harder when faced with difficult work. Concerns Over Inequality and TechnologyDespite the gains, officials warned that averages hide disparities.
“There is a clear pathway. Inequality is one of the things we have seen. There is a lot of inequality between schools,” Dr. Nkoya said.
Mr. Bousquet also flagged digital use. Zambian learners average almost 2 hours per day on digital devices — below the OECD average. He cautioned that the focus should be on how technology is used, especially with AI entering classrooms.
“They must teach them how to use it responsibly — including how to verify information, recognise limitations and judge whether sources are trustworthy,” he said.
He added that while teacher recruitment is positive, more money alone will not sustain gains without improvements in teaching, curriculum, school safety and learning time.
The 2025 PISA results will be compared with Zambia’s 2026 National Assessment Survey to validate findings. The country is also expected to join PISA 2029 on a computer-based platform, which will provide more detailed data.
Dr. Mambwe said the Ministry will review implications for teaching, teacher development, curriculum, assessment and school leadership.
“We must ensure that data and evidence do not remain confined to reports,” he said.
