I agree with ehh2109's position. As others have also mentioned, you will need to get more research experience to gain acceptance into Clinical PhD programs. If this type of experience is not available to currently available in your program, looking for paid and/or volunteer RA positions a good start. To note, RA jobs usually require you to make a 1-2 year commitment. Further, while I agree with ehh2109 that it will be hard to get such a job without some research experience under your belt, it is not impossible. Sometimes it is easier to train someone with very little experience because they have not developed any bad habits and are more motivated to do well. Don't be dissuaded from applying to these positions because of inexperience. We all start somewhere.
Having said that, I personally believe that all students pursuing graduate study should gain research experience to see how you they feel about conducting science in the field and all that it entails. It is not a picnic and a lot of people learn that its not for them. A 5-7 year commitment is a big undertaking if your not interested in what you are doing.
Along those same lines, I would also look to see if you can volunteer and/or work part-time in a clinical setting that provides services to the population you are interested in studying and/or working with as a clinician. While this is probably less important than the research piece, with respect to applying, it demonstrates interest and will also give you exposure to clinical work. You might find that you enjoy it or that its not for you. In line with what I said above, if you are not interested in what you are doing, 5-7 years is a long time.
If you pursue exposure to clinical work, I would suggest that you look into group homes, psychiatric hospitals, or non-profit programs in the locale area. I would also check with your psychology department to see if they offer these opportunities. My undergraduate university did and it was a wonderful experience for me, as it helped shape my research and clinical interests.
My last piece of advice would be to purchase or borrow the "Insider's Guide to Graduate Programs in Clinical and Counseling Psychology." If you have not already at it, it is a good read for someone interested in graduate study. Looking over this and the threads of SDN will be quite informative.
I wish you the best of luck in your pursuits 🙂
