Every K-8 school has a teacher on staff designated as the "GATE Lead Teacher." This teacher may or may not teach GATE students, as their responsibilities include communicating with the district office about GATE-related items, as well as assisting with/coordinating GATE testing and activities at the school-level, but do not require that they teacher upper-grade students.
You can email this person to ask questions regarding the GATE program at your specific site, such as general questions about instruction, or extra-curricular activities and events, but any questions, comments, or concerns regarding specific teachers will be directed to administrative support staff.
