**Core Concept**
The question is testing the understanding of the definition and purpose of a reform school, also known as a juvenile reform school or correctional facility. This type of institution is designed to provide a controlled environment for delinquent or troubled youth who require more intensive supervision and rehabilitation than a traditional school setting can provide.

**Why the Correct Answer is Right**
In many countries, including the United States, boys over 16 years of age who are deemed too difficult to manage in a certified school or are misbehaving may be referred to a reform school. The primary goal of a reform school is to provide a structured environment that promotes behavioral change, academic education, and personal growth. The staff at reform schools typically include trained educators, therapists, and counselors who work together to address the individual needs of each student.
