Abstract
Background:

No Student Registered Nurse Anesthetist (SRNA) clinical evaluation instrument (CEI) has undergone interrater reliability or usability testing, to the authors' knowledge. This project determined the interrater reliability and usability of a new SRNA CEI.
Method:

This was a prospective, mixed qualitative and quantitative, fully crossed observational design with a usability survey. SRNAs' recorded performance during simulation was evaluated by participants, who also completed a usability survey.
Results:

Interrater reliability is high, intraclass correlation coefficient = .982, 95% CI [.884, .960], indicating strong agreement of SRNA clinical performance among participants (n = 10). Internal consistency is excellent (Cronbach's α = .943), indicating the CEI is constructed appropriately and participants found it easy to use.
