Any Last Questions Before You Contact Us?
Here’s a list of questions we often receive, as well as the answers to them.
If your question is not on the list, feel free to reach out to our Solutions Team.
Each module has multiple instructional videos, followed by a 10-question quiz. This quiz is primarily a learning exercise: the instant feedback will help you better understand the most important lessons from the module. You can answer the questions as many times as you want, until you get all the answers right. So, no stress!
The final exam consists of two parts. After you’ve completed all modules belonging to the part you’re working on, you’ll receive an invitation to take its exam. Both online exams are approximately 1 hour in length, and you can take them whenever and wherever you want.
To pass the exam, you need to answer 70% of the questions of each of the two parts correctly. No worries: if you prepare thoroughly, we’re confident you’ll make it. If you don’t pass the first time, you can still take two additional exams ($ 97 each) for both parts.
You’ll follow the same modules on the Principles of Persuasion that the Cialdini Influence Practitioner program offers (modules 1–10). However, that’s only half of your learning program. You’ll also follow a high-level coaching program with instructional videos (modules 11–12) and coaching by Dr. Cialdini’s Faculty members.
