The National Association of Social Workers has continuing education programs designed to help social workers prepare for the license renewal requirements exam. Consult them about online study resources and exam preparation courses.
The social work exams are multiple choice. Using the online sample tests, familiarize yourself with thinking in this format. As a rule, you can usually eliminate two of the four choices. If you are struggling to choose between two and feel either might be the correct answer, go with your gut feeling. Unless you have good reason, don't go back and change your mind.
The more you work with the electronic format, the more you will feel comfortable with it. Going into the exam cold isn't a good idea, as you will spend too much time figuring out how things work. Take several practice tests so that you can walk in on exam day with the confidence to go right into the material. Live and audio recorded courses and print materials are also available to prepare you for the exam.
Know terms that are specific to social work, such as "latency aged" and "intermittent explosive disorder." Part of being a professional is knowing the jargon that goes with being able to converse with peers.
"Get a good night's sleep before the exam" may sound trite, but that doesn't mean it isn't good advice. Cramming the night before and wandering into a four-hour exam sleep-deprived isn't a good formula. Instead, prepare for exam day by resting and eating properly.
