This article describes the implementation of a special accommodations policy for a suite of localised English language and numeracy tests, the Workplace Literacy and Numeracy (WPLN) Assessments. The WPLN are computer-delivered assessments, part of the WPLN training and assessment programme, which exists to provide access to workforce skills training across the Singaporean population. Operational and interview data were analysed to investigate three main areas: the extent to which WPLN accommodations are considered appropriate and effective for the test-taker population; the impact of the accommodations on test-takers' future opportunities; and the main factors perceived by stakeholders as playing an important role in test accommodations. The findings indicate that while the accommodations provided are generally considered to be appropriate and effective for the diverse WPLN test-taker population and facilitate improved future educational and workplace opportunities, some areas of the process are problematic or worthy of further consideration. Specifically, recommendations are made for future improvement in special accommodations policy development, dissemination, and implementation in large-scale test systems to safeguard access and inclusion.
