School counselors provide academic, social-emotional, and college and career access information to all students via core curriculum classroom lessons. English Learners benefit from differentiated classroom instruction that makes content engaging and accessible. Despite this need for differentiated instruction, few educators have received English as a Second Language (ESL) teaching strategies training. This mixed methods study examined how an ESL teaching strategies workshop influenced the utilization of these approaches by school counselors in training. A triangulation mixed methods design was used to collect complementary data about participant behavior and thinking. Modeling ESL strategies alone did not yield statistically significant differences in the types of strategies implemented by school counselors in training. However, participants did become more aware of the needs of English Learners and actions that could promote classroom engagement. Implications for training, research, and the scholarship of teaching and learning are discussed.
