The word "try-outs" refers to a process of evaluating a person's skills or talents in order to determine their suitability for a particular activity or a role. Some of the synonyms for this term are "auditions", "screenings", "casting calls", "tests", "trial runs", "experiments", "samples" and "demonstrations". These terms are often used in the context of sports, music, theater, and other performance-related fields. They all imply the process of trying something out or testing oneself in a specific capacity, with the aim of achieving a certain goal or outcome. Therefore, whether you use try-outs, auditions, or casting calls, the process is essentially the same.
