Stage 1 = Engagement. Stage 2 = Consideration of Feasibility. Stage 3 = Readiness Planning. Phase 1 = Pre-Implementation. Phase 2 = Implementation

^aSites with a known end-status on the start-up outcome (i.e., they have either achieved start-up or discontinued) may still be ongoing during Phase 2. Since ongoing sites may go on to complete more activities during Phase 2 before achieving competence or discontinuing, the proportion scores for ongoing sites are skewed negative in a manner that misrepresents those sites’ ultimate Phase 2 implementation process fidelity. Therefore, Phase 2 proportion scores are only reported for the subset with a known end-status for achieving competency
