Incorrect PIRLS Finding Points to Urgent Areas for Support in Education

Revisiting PIRLS Findings and Data Errors

On Sunday, 25 October the Sunday Times reported that education economist Prof. Martin Gustafsson had uncovered a fundamental error in the 2016 Progress in International Reading Literacy Study (PIRLS) data for South Africa. The PIRLS had initially found no improvement in grade 4 reading levels, but this was later proven incorrect, with South Africa showing significant gains.

The Role of PIRLS in Measuring Education Outcomes

Outside of matric results, PIRLS—alongside TIMSS and SACMEQ—is one of the key tools used to assess learner performance nationally and internationally. Its findings have significantly influenced education priorities, particularly the focus on literacy as a national imperative.

Persistent Literacy Challenges Despite Improvements

Although the stagnation finding was incorrect, the reality remains that most learners struggle with reading comprehension. A significant proportion of learners are unable to read for meaning by the end of grade 4, and South Africa continues to lag behind international peers.

South Africa’s Measurement Problem

The PIRLS data issue highlights a deeper systemic problem: the lack of reliable, ongoing national assessments. Without consistent early-grade measurement, it becomes difficult to track progress, identify challenges early and implement timely interventions.

The Need for Early and Continuous Assessment

A robust national assessment system—similar to the former Annual National Assessments (ANA)—is critical to understanding learner progression before Grade 12. Waiting for matric results or periodic international studies is insufficient for guiding system-wide improvement.

Strengthening Systems and African Language Benchmarks

Beyond learners and teachers, systemic elements such as assessment frameworks, district support and language benchmarks are essential. There is a critical need to develop standardised reading benchmarks for African languages to better understand learner progress and address gaps in literacy development.

The Role of Social Investment in Literacy Improvement

Social investors have a key role to play in strengthening literacy systems, particularly through funding, collaboration and supporting large-scale initiatives. While improvements in PIRLS offer some optimism, sustained and deliberate investment in literacy—especially at foundational levels—remains essential to long-term education reform.
