Collaboration in the school setting is a vital component to student success. Two key stakeholders who support and advocate for English Learners (ELs) are school counselors and English to Speakers of Other Languages (ESOL) teachers. The authors of this manuscript conducted a research study to measure school counselor and ESOL teacher perceptions and attitudes about collaboration by using a semantic differential scale developed by Gibbons et al. (2010) to measure school counselor perceptions and attitudes of collaboration. The sample included 105 original responses which were collected prior to removing incomplete responses. A total of 82 responses were retained for the data analysis which included school counselors (n=54) and ESOL Teachers (n=28). The findings from this research study suggest varying attitudes about collaboration among these two stakeholders and yield factors that can influence educator training, practice and research. Factors examined include geographical location, district type, and years of experience.
