Grade 12 Mathematics National Senior Certificate Examination Papers’ Task Cognitive Levels: Do They Align with the CAPS Recommendations?

Mathematics education policy in South Africa specifies a structured distribution of cognitive demand in school-leaving examinations intended to promote a balance between procedural fluency, conceptual understanding and problem-solving. However, there is limited empirical evidence on the extent to which the alignment between the Curriculum and assessment Policy Statement (CAPS) Programme of Assessment (PoA) cognitive demand requirements and the cognitive demand of National Senior Certificate (NSC) mathematics examination tasks. Guided by the Mathematical Task Framework (MTF) cognitive demand categories, this study employed a quantitative content analysis of publicly available Grade 12 Mathematics NSC examination papers (Paper 1 and Paper 2) from 2018 to 2023. A purposive, criterion-based sampling strategy was used to select 12 examination papers (two papers per year across 6 years), ensuring coverage of consecutive national examination cycles. The study is theoretically grounded in the integration of the MTF and CAPS PoA, which together provide a framework for analysing cognitive demand in mathematical tasks. Each examination task was coded according to a structured MTF–CAPS analytical framework, and alignment was assessed by comparing observed cognitive demand distributions with CAPS-prescribed weighting. The inter-rater reliability between coders was substantial (Cohen’s κ=0.71) indicating acceptable coding consistency. Findings indicate a persistent overrepresentation of routine procedural tasks across the 6 year period, consistently exceeding CAPS recommendations, alongside a low and often negligible proportion of complex procedures and problem-solving tasks. This pattern was consistent across both examination papers. Statistical analysis further confirmed a significant deviation between observed and expected cognitive demand distributions. These results indicate a systematic misalignment between the intended curriculum and the assessed curriculum in Grade 12 mathematics examinations. Rather than reflecting the full cognitive spectrum outlined in CAPS, the examinations predominantly emphasise procedural forms of mathematical activity, thereby limiting opportunities for engagement with higher-order mathematical reasoning as defined in the curriculum framework. This study contributes new empirical evidence on the alignment between the cognitive demand levels of Grade 12 mathematics NSC examination tasks and the CAPS PoA recommendations in South Africa. Unlike previous studies that focused on textbooks, classroom practices, or international assessments, this study specifically examines high-stakes national examinations and highlights a significant misalignment between the intended and assessed curriculum. The findings contribute to debates on curriculum implementation and assessment quality by showing how assessment practices may limit learners’ opportunities to engage in higher-order mathematical reasoning and problem-solving.
