In City of Santa Cruz v. Santa Cruz City Schools Bd. of Education (1989) 210 Cal. App. 3d 1, the issue was framed as whether or not there was substantial evidence to support the trial court's implicit finding that the Santa Cruz High School's Memorial Field, including its lights, was "used for or directly related to student instruction." ( Id. at p. 8.) The evidence showed that Memorial Field was used primarily for physical education classes, interscholastic athletics, spirit activities, and band performances, these activities were an integral part of the high school's educational program, and students received academic credit for participation in those activities. (Ibid.) This court concluded that the evidence was sufficient to support a finding that Memorial Field served an important educational purpose and was "directly used for student instruction." (Ibid.)
