Teacher readiness is crucial for the successful implementation of reforms in 2017. The revised Primary School Standards-based Curriculum (KSSR) was used by the Malaysian Ministry of Education (MoE) to issue the Standards-based Curriculum and Assessment Document (DSKP) for Visual Arts Education (VAE). This study aims to identify the level of understanding, implementation of teaching and learning (T&L), and classroom assessment (CA) practices among primary school VAE teachers based on the DSKP KSSR VAE. Through systematic random sampling, 246 primary school VAE teachers in Selangor participated in an online survey. The study findings indicate that primary school VAE teachers have a high level of understanding (mean = 4.33, SD = 0.683), high T&L implementation (mean = 4.31, SD = 0.641), and high CA implementation (mean = 4.29, SD = 0.637). Pearson correlation analysis reveals a significant positive linear relationship between understanding and T&L implementation (r = 0.698, p = 0.00), as well as the relationship between understanding and CA implementation (r = 0.636, p = 0.00). Overall, primary school VAE teachers in Selangor exhibit a strong understanding of DSKP KSSR (2017 Revision) VAE and effectively implement T&L and CA practices. Recommendations for future research include exploring other factors influencing teachers' understanding and implementation, such as locality disparities between urban and rural schools.
