PECS IV+ is the solution for transitioning from PECS® to high-tech AAC. For learners who have mastered Phases I through IV of the Picture Exchange Communication System® using traditional PECS books, PECS IV+ is the high-tech next step! From Pyramid Educational Consultants, the developers of the evidence-based and world-renowned PECS®, PECS IV+ allows users to construct a multi-picture Sentence Strip™ via a dedicated Sentence Starter™ page and up to 20 digital PECS book pages for the in-app voice to speak.

Features of PECS IV+:
• Looks like a traditional PECS book with colored, tabbed pages with VELCRO® strips and a Sentence Strip so you can create a PECS IV+ book that looks identical to your student’s PECS book
• Drag and drop pictures from the tabbed pages to the Sentence Strip just like with a traditional PECS book
• Switch between pages by scrolling between and tapping on different tabs
• Rearrange pictures on the Sentence Strip without having to delete pictures
• Clear Sentence Strips with a single button push or clear individual pictures by swiping them back to the book
• Includes over 1,000 Pics for PECS images
• Integrated features from the PECS protocol such as constant time delay for the in-app voice

Customize each book:
• Open or close the dedicated Sentence Starter page with a single touch
• Create 1-20 tabbed pages
• Up to 24 pictures per page
• Customize each page by number of VELCRO® strips, color, category icon, and/or number of pictures on each page

Customize pictures:
• Use any of our included Pics for PECS images or add images from your photo library
• Change text on pictures
• Put text on top or bottom of pictures, or remove text from pictures
• Change size of pictures
• Search function for the Pics for PECS library included

• Use included customizable synthesized speech (AVSpeechSynthesizer) or record your own speech
• Incorporate the research-based constant time delay for ‘reading’ the Sentence Strip to create opportunities for the student to speak

Select from included profiles or create new profiles to customize:
• How pictures are moved: tap, drag or both
• How to clear (reset) the Sentence Strip
• Visibility of Sentence Starter page
• Reading Sentence Strip left to right or right to left
• When to read the Sentence Strip: as each picture is selected or with a single tap of the “Speak” button after the Sentence Strip is completed

Track student’s usage:
• Day by day list of Sentence Strips constructed by the student
• Weekly and monthly analysis of most frequently-used pictures

Pyramid Educational Consultants does not recommend starting functional communication training with an app or a speech generating device because these high-tech options do NOT require the social interaction that is crucial to communication and is the cornerstone of the Picture Exchange Communication System. Functional communication training should begin with a traditional PECS Communication Book. Research has shown that most learners can learn Phases I through IV of the low-tech PECS Communication protocol within 3- to 9-months.

Should sync across devices

I think that the app should sync across devices, so you don't have to reload tons of pics! Very inconvenient, especially for children.

Low tech to high tech

The PECS phase IV+ app is the perfect transition system for students who are going from a communication book to a sound generating device. The jump from a communication book to a large vocabulary system can often be to overwhelming and we lose the student. This app is a stepping stone for many of our students and seeing their communication book on the iPad makes sense to them and is an easy transition. We build vocabulary and work on expanding sentences while they continue to utilize functional communication. While the Phase IV+ app has many features and qualities to facilitate a student transitioning for it to be on par with other communication apps it highly needs a way to back up the student’s individualized and specific pages. Working in a school system where students devices get broken or changed a back up forum is a necessity. This app is perfect for those students who are capable of creating sentence and mastered Phase IV, sentence structure. They have learned how to communicate and will now learn how to use a high tech system that is individualized to their personal communication book.

So many issues

Has an artificial limit for some reason. People have been asking them to up the limit or remove it, but they don’t care. The page’s will randomly lose their layout. It also desperately needs a sync feature. Do yourself a favor and get something better.
