When should my child switch from PECS to an AAC app?

Ask an AAC-trained speech-language pathologist. There is no single symbol count or age rule that fits every child. The decision should consider motor access, language goals, settings, and training.

Does OAP funding cover AAC devices?

Yes. AAC devices and apps are eligible OAP expenses when recommended by a speech-language pathologist as part of the child's therapy plan. This includes iPads with AAC software, dedicated communication devices, and PECS materials. The Assistive Devices Program (ADP) through OHIP may also contribute to device costs.

Which AAC app is best for autism?

The most widely used AAC apps for autism are Proloquo2Go, TouchChat with WordPower, and LAMP Words for Life. The best choice depends on your child's motor skills, language level, and learning style. A speech-language pathologist experienced in AAC should assess your child and recommend the most appropriate system. Many apps offer free trials.
