It is widely accepted that students with additional support needs beneﬁt substantially from the implementation of individualised, intentional and planned interventions (e.g. Pretti-Frontczak and Bricker 2000; Wolery 2000). These interventions are usu- ally reported in the Individualised Education Programme (IEP) that constitutes the educational map for students with disabilities (Ruble et al. 2010) and contributes to ‘bridge (…) “what is” and “what can be”’ in students’ life (Thompson et al. 2009, 138). These geographical metaphors are pertinent because they suggest a parallel between a journey and the three central dimensions of an IEP (Bateman and Herr 2006; Lee-Tarver 2006): (a) a speciﬁc departure point – the child’s present level of performance; (b) a personal destination – measurable goals; (c) an individualised route and vehicle – needed supports and services. Individualisation, therefore, has been described as the nuclear factor for intervention effectiveness (Wolery 2000).
