The iPad with the Proloquo2Go application has taken the world of autism by storm, and given individuals that do not have a voice, a voice. This study looks at the effectiveness of the iPad with the Proloquo2Go application to enhance the manding repertoire for children with autism. Participants included three children (2 girls and 1 boy) diagnosed with an autism spectrum disorder, or exhibiting characteristics of an autism spectrum disorder, between the ages of 3 and 5. A multiple probe design across participants was used to assess the effectiveness of the iPad. Methods included completing The Reinforcer Assessment for Individuals with Severe Disabilities (RAISD) with the parents and/or teachers of each participant and running a six stimuli preference assessment before implementing each Phase. Pretest probes were conducted before implementing Phases 1 through 4. These phases were comparable to Phases 1 through 4 of the Picture Exchange Communication System (PECS) (Bondy & Frost, 1994). Results of this study support that children with autism can acquire the skills needed to mand using the iPad with the Proloquo2Go application with training comparable to that of the Picture Exchange Communication System (Bondy & Frost, 1994). In addition, vocal requesting increased for the participants during the training phases in comparison to pretest probes.
