The establishment of Tanque Verde High School was a considerable controversy in the community. The school district endured a recall election when the school board split on whether to build a high school on North Catalina Highway. One member, a proponent of the high school, was voted out of office in favor of a replacement candidate who shifted the board majority to opposition of the high school. The proposed site was abandoned. However, the school board ultimately voted to open the high school on the same campus as Emily Gray Junior High School, avoiding the need to acquire a separate high school site. As of the 2011-12 school year, Emily Gray Junior High was relocated to a new campus.
