Revisiting the English language test of Singapore’s primary school leaving examination: a comprehensive validity review

This study reviews the English language test of Singapore’s Primary School Leaving Examination, a high-stakes national assessment taken annually by nearly all primary six students for secondary school placement. Given the test’s importance in shaping students’ academic pathways and recent format changes, it is crucial to evaluate its validity, specifically its ability to provide accurate and fair assessments of students’ English language proficiency and academic readiness. The review outlines the test’s educational and policy context, followed by a description of the latest formats for both the English language and foundation English language versions. The analysis focuses on core dimensions of test validity, including content representativeness, construct validity, criterion-related validity (concurrent and predictive), and reliability (inter-rater reliability and internal consistency). Drawing on official documents and limited empirical studies, the review finds moderate improvements in content representativeness and construct validity. However, both longstanding and emerging concerns (e.g., the exclusion of local linguistic norms and genre scope) indicate that key limitations remain. While predictive validity, inter-rater reliability, and internal consistency appear supported, empirical research remains sparse across all reviewed test qualities, particularly in concurrent validity. The review integrates identified research gaps and proposes inquiry directions to inform future test development and policy adaptation. Strengthening the evidence base is essential for ensuring a valid, reliable, and equitable assessment system in Singapore’s primary education landscape.
