22 Pa. Code § 171.22
Supervisor
In a private school for severely disturbed children, the lack of a full-time classroom supervisor who is free to perform his functions unrestricted by classroom obligation is a deficiency which prevents the school from meeting the Approved Private School Standards contained in subsection (b). Wiley House v. Scanlon, 465 A.2d 995 (Pa. 1983).
The Secretary is not plainly erroneous in construing 22 Pa. Code § 171.22(b) to require that an approved private school employ a supervisor who is fully able to supervise without the burden of concurrent teaching obligations. Wiley House v. Scanlon, 432 A.2d 324 (Pa. Cmwlth. 1981).
