Which member of the Commission on Professional Standards must come from a private school?

The member of the Commission on Professional Standards who must come from a private school is a representative of the general public. This requirement ensures a broader representation of educational stakeholders and perspectives within the commission, reflecting the interests and experiences of those involved in private education. Having a member from the private school sector helps to balance discussions around educational policies, training standards, and professional practices, ensuring that private school viewpoints are considered alongside those from public educational institutions.

The other options focus on specific professional roles within schools, such as classroom teachers, school administrators, and counselors/psychologists, which are primarily affiliated with public school systems. These roles do not require representation from a private school, making the representative from the general public the correct choice to fulfill that criterion.
