Obtaining ratings of each person independently by several raters who are highly trained in observing interviews would be the best strategy for achieving high inter-rater reliability. This is because having multiple highly trained raters reduces the impact of individual rater bias or error and increases the likelihood of reaching a consensus or average rating that is more accurate. The other options either involve only one rater, fewer or less trained raters, or untrained raters, which may result in lower reliability and validity of the ratings.
