Which of the following people should the teacher approach to get help for the student and her family?

While the school psychologist can provide valuable insights into a student's mental health and learning challenges, their primary role focuses on psychological assessments and interventions rather than direct family support. Thus, they may not be the best first point of contact for addressing family-related issues.

The school parent-teacher organization (PTO) primarily focuses on fostering parental involvement and enhancing communication between parents and teachers. Although they can be supportive, they are not equipped to provide the professional guidance or direct assistance that a family may require in dealing with specific student issues.

The school principal oversees the entire school and ensures that educational standards and policies are upheld. While they can provide direction and resources, they are less likely to have the specific training to address individual student and family concerns directly, making them a less suitable option for this situation.
