Unless I am reading incorrectly, NOTE 1 under COM.01500 states that ungraded PT programs are acceptable:
"NOTE 1: Appropriate alternative performance assessment procedures include participation in an external PT program not required by CAP; participation in an ungraded/educational PT program; split sample analysis with referral or other laboratories, split sample analysis with an established in-house method, use of assayed materials, clinical validation by chart review, or other suitable and documented means. It is the responsibility of the laboratory director to define such alternative assessment procedures and the criteria for successful performance in accordance with good clinical and scientific laboratory practice."
Based on this, I would think that the J survey meets these requirements.
