Final answer:
A social worker typically needs a minimum of a four-year bachelor's degree (BSW) for entry-level positions, with many positions requiring a master's degree in social work (MSW). Licensing is also required in most states.
Step-by-step explanation:
To call yourself a social worker, you must have a specific educational background. Typically, this includes obtaining a degree in social work or a closely related field. A four-year bachelor's degree in social work (BSW) is the minimum requirement for entry-level positions. However, many social work positions require a master's degree in social work (MSW), especially for clinical work that involves diagnosing and treating mental, emotional, and behavioral issues.
Furthermore, after obtaining a degree, most states require social workers to be licensed, certified, or registered, which involves additional coursework and passing a licensure exam. Continuing education and keeping up with current research and techniques are also important for a social worker's career advancement.
