Abstract Advanced practice providers (APPs) graduate from school with variable hospitalist experience. While hospitalist‐specific onboarding is recommended for hospitalist APPs, no standard method currently exists to assess their readiness for practice. We created a 17‐item instrument called the Cardin Hospitalist Advanced Practice Provider‐Readiness Assessment (CHAPP‐RA) to assess APPs'; readiness for practice using a milestones‐based scale. We piloted CHAPP‐RA at a single site where 11 APPs with varied experience were rated by 30 supervising physicians. Supervisors also provided global ratings for overall performance. We investigated the feasibility of CHAPP‐RA and collected validity evidence for the interpretation of scores. The mean time to complete one CHAPP‐RA was 10.5 min. Supervisors rated novice APPs lower than more experienced APPs, p ≤ .001. CHAPP‐RA ratings also correlated strongly with global ratings. CHAPP‐RA is feasible to implement and has initial validity evidence.
