Which of the following best describes a 'core function: screening'?

The concept of 'core function: screening' primarily involves the process of determining a client's eligibility for a program. This is a critical step in service delivery, as it helps professionals assess whether a client meets the necessary criteria to benefit from a particular treatment or support program.

Screening typically entails gathering information about the client's background, current situation, and specific needs. This information is then used to identify appropriate services that align with the individual’s needs and circumstances. By effectively conducting the screening process, practitioners can ensure that clients are directed to the most suitable resources, thereby optimizing treatment outcomes.

While identifying external support systems, providing family counseling, and delivering direct treatment services are all important aspects of working with clients, they do not encapsulate the primary focus and purpose of the screening function, which is fundamentally about assessing eligibility and suitability for specific interventions.
