Reliability estimates of interobserver agreement is best established when observers share behavioral definitions before or after data collection, but are not able to view what each other is recording.
When two or more independent observers measure the same events, interobserver agreement (IOA) refers to the extent to which they report the same observed values. The IOA Research & Assessment Committee was founded in late 2014 with the aim of improving organizational ombuds practice by better understanding ombuds practices and by encouraging research-based professional development.
