This document discusses applying Bloom's Taxonomy of educational objectives to grade English texts in terms of difficulty for non-native English translators. The study had 30 Iranian English translation students take a translation test with 6 passages graded based on the cognitive processes (knowledge, comprehension, application, etc.) required. Results found translator performance quality aligned with expected difficulty based on Bloom's levels, except for the synthesis text. The findings support using Bloom's Taxonomy to assess translation quality and reliability, and to teach translation skills.
