Existing studies have shown that academic performance deficits of students with SEN are resulted from their cognitive impairments. Cognitive trainings can improve their academic results with a lower cost in time, money, and potential side-effects, comparing to other behavioral therapies and medications. Therefore, we suggest that designing a cognitive training platform for students with SEN can tackle most of the fore-mentioned problems. In this online training platform, materials are designed for students in primary grade 1 to grade 6. For each grade, students will have to identify themselves with their respective SEN group (i.e., Chinese Dyslexia, AD/HD, or ASD). For each SEN group of all grades, there will be six or more cognitive training tasks that are age-appropriate and focus on the respective deficits. All of the adopted cognitive trainings can be incorporated in the online system easily, without the need of additional trainers, and have been proven effective in previous  studies targeting the respective SEN groups
