If an audit by the superintendent of public instruction finds that an approved in-service education agency is not in substantial compliance with the provisions of this chapter, the superintendent of public instruction shall document violations of the regulations—i.e., written findings of fact and conclusions of law—and notify such provider of corrective action necessary to achieve substantial compliance. If such in-service education agency fails to provide an assurance within twenty calendar days that such corrective action will be implemented, the superintendent of public instruction shall notify the agency that it is no longer eligible to provide continuing education credit hours in its in-service education program until the agency provides an assurance to the superintendent of public instruction that corrective action will be implemented which will satisfy the substantial compliance standard. If the approved in-service agency has more than one department or section operating in-service programs, then only the department or section within such agency that fails to comply with the provisions of this chapter shall no longer be eligible to provide continuing education credit hours.
