This academic critique examines the effectiveness of Nessy Reading and Spelling, a computer-assisted reading intervention (CARI) that adopts a game-based approach, designed to develop reading and spelling skills in primary-aged children. Nessy employs a structured literacy approach with a focus on phonological awareness, aligning with the explicit and systematic synthetic phonics guidance promoted by the Department for Education in England. Due to the paucity of published research on Nessy, a systematic literature review was conducted to explore whether game-based or gamified digital reading interventions are effective in supporting the development of literacy skills in primary-aged children in mainstream primary schools. Although the findings suggest that CARIs can enhance phonemic awareness and motivate struggling readers, evidence on their long-term effectiveness remains limited. Furthermore, methodological challenges complicate the drawing of conclusions regarding the impact of CARIs compared to traditional interventions. While findings indicate positive effects on word reading and spelling accuracy, as well as student motivation and engagement, they also suggest the need for sustained intervention support to develop reading fluency and raise concerns over the potential for declining intrinsic motivation over time. This critique concludes that while Nessy offers a promising supplementary tool for struggling readers, further longitudinal research is needed to evaluate its long-term effectiveness and its potential to complement or replace traditional literacy support. Implications for educational psychology practice emphasise the importance of a balanced, evidence-informed approach when suggesting CARIs for literacy support.
