Final answer:
The correct term for the ratio of staff members to children in a child care facility is A) Staff-to-child ratio. It's an important aspect of childcare to ensure adequate care and supervision, with recommended ratios for counselors on college campuses as well.
Step-by-step explanation:
The term used to describe the ratio of staff members to children in a child care facility is A) Staff-to-child ratio. This ratio is crucial for ensuring that each child receives adequate care and supervision. The International Association of Counseling Services recommends one full-time equivalent staff member for every 1,000 to 1,500 students. However, there is concern that the staff-to-student ratio is too high, which might be contributing to the mental health issues experienced by a significant number of students. In contrast, the measure that compares the number of men to women in a population is known as the sex ratio.
