If your partner is willing to participate in the TA effort, they are welcome to be a part of the process; however, TA Card funds can only be utilized to pay TA Vendors available through the TA Catalog. ACOs and CPs are also welcome to combine TA Cards to work together on a larger TA project. (Projects focused on developing shared workflows and/or data sharing between ACOs and CPs are two examples of potential ACO/CP combined TA projects.)
