Back in 2006 when first hearing about the CAPS program and beginning to teach it, the phrase "aging-in-place" didn't sit well with a lot of people that were taking the CAPS coursework. They just didn't like the idea of "aging" and referring to it so prominently. They wanted a softer term. There definitely was pushback.
It's not limited to any particular geography or part of the world either. This concept has really caught on so jump in and use your specialty (for instance remodeling, OT, design, or consulting) to help create effective solutions for people.
For those who have earned the CAPS designation, proudly refer to it and use it on websites and other marketing.
