Self-assessment skills are emphasized in signed language Interpreter Education Programs (IEPs), and it is well-established that self-assessment is an essential element of a sign language interpreter's professional development, yet anecdotal evidence suggests that practicing interpreters frequently do not engage in self-assessment. This study aimed to determine the type and extent of technology-mediated self-assessment strategies used by graduates of four-year undergraduate Interpreter Education Programs. This study also examined the reasons IEP graduates do or do not continue to utilize the self-assessment strategies that were taught during their program, their perceptions of how self-assessment has impacted their work, and technologies that support their efforts. For the purpose of this study, self-assessment was defined as intentional evaluation of personal interpreting product or process. A sequential explanatory mixed-methods design was used to explore how graduates of four-year IEPs utilize self-assessment strategies. An online survey was distributed to graduates of four-year IEPs in the state of Florida, and survey respondents were asked to volunteer to participate in follow-up virtual semi-structured interviews to gather additional data. Survey and interview data were analyzed, and the results indicated that while participants found self-assessment to be beneficial to their work, overall they did not continue to use the formal self-assessment strategies they had learned during their IEP after graduation. However, they did continue to assess their work through informal strategies such as reflection, discussing work with colleagues, and self-monitoring. Because they favored more informal self-assessment, participants also did not have a need for the same level of technology that they utilized to conduct formal self-assessments in their IEP, preferring screen-recordings and texting colleagues to programs designed for self-assessment.
