Each university-affiliated school has a unique relationship with a college or university and a different grade configuration.
One-way mirrors and speaker/intercom systems allowed a professor to silently observe the classroom, but without being seen by the students or the student-teacher.
The standard rooms are outfitted with CCTV cameras hidden inside black plastic domes on the ceiling.
Complex lens optics and multiple cameras allow a single stationary dome to view 360 degrees, with no mechanical noises or moving parts.
High-speed Internet connections allow for a professor at a college to remotely view and interact with student-teachers in a distant laboratory school.
