What is the core function that includes the process to complete all documentation for admission?

The core function that includes the process to complete all documentation for admission is Intake. This phase is crucial as it involves gathering essential information from the client to understand their situation and needs, allowing for the proper alignment of services to be provided. During the Intake process, counselors collect data such as personal history, substance use details, and relevant background information, which contributes substantially to the overall treatment planning.

Intake not only focuses on documentation but also helps establish rapport with clients, setting the tone for future interactions and guiding them through the entry into the treatment system. It serves as a foundational step prior to the more in-depth Assessment phase, which goes beyond mere admission documentation to evaluate the individual's mental health and substance use issues.
