Yes! I only had 3 credits of undergrad research experience, and it was totally unrelated to PT or health care. BUT that experience was still the most significant talking point in all of my interviews (and several of my essays). Faculty seemed genuinely interested in the fact that I even had research experience at all. I was even asked several follow up questions about the content of my research (even though, like I said, it wasn’t remotely PT-related)
It’s hard to quantify how much something like research experience is valued by programs, but being consistently asked about it in my interviews seems like a reasonable flag for its value
