In 2008, Belgium formally ratified the Convention on the Rights of Persons with Disabilities (2009), which together with the Salamanca Statement (1994), became the inspiration for the Flemish M-decree on pupils with special educational needs (Decreet betreffende maatregelen voor leerlingen met specifieke onderwijsbehoeften, 2014). An important part of this decree entails the right to reasonable accommodations (Article 24, 2C) to be able to include students with special educational needs (SEN). Recently (2021), reasonable accommodations (RA) were included in the Belgian constitution (Title II, article 22), which strengthens the legal background of RA even more. Consequently, students with SEN and their parents have the legal right to ask for RA to make the school environment more accessible. RA can take on many forms, like providing additional instruction, providing more time to finish tests or tasks, providing supportive educational materials (e.g., headphones, reading and writing software), or providing extra structure in the classroom and school environment. (Gunter et al., 2000). When deciding upon RA, they should always entail individualized measures that compensate for the needs the student is struggling with (de Beco, 2014). Although many scholars (Jansen et al., 2017) have investigated the results or output of a decision-making process on RA (e.g., for students with an Autism Spectrum Disorder) and are focusing on received accommodations, this inquiry attempts to grasp the decision-making process from the parents' point of view. In national and international literature, parents' position regarding the decision-making process on RA is often unquestionable. First of all, parents are often missing as important partners around the table in deciding upon RA for their child with SEN (de Boer et al., 2010; Mann et al., 2015; Van Miegem et al., 2018). Considering the position of students with SEN, whose participation is also often neglected, scholars report on the missing voices of parents and students. Secondly, the term RA is often unclear and unambiguous (Meta-evaluatie M-decreet, 2017). Parents (and professionals) miss a decretal background and clarification within the leading M-decree. Third, RA are often strongly dependent on the school policy on support for students with SEN (Struyf et al., 2015). A policy that parents are sometimes not aware of. For example, some parents reported a special education transfer when the school denied RA. At last, Belgium is still a worldwide leader in referring students to special education (EASIE, 2018), which can be an indication that the decision-making process on RA is missing some practical insight to guide parents and students in a direction towards an inclusive school trajectory. This IPA study is part of a larger research project, in which the decision-making process on reasonable accommodations for students with special educational needs is the focus point.
