The PMI-ACP exam is a bit different as there isn’t a PMBOK available. In fact, when I was first signing up for the test, I was astonished to learn that PMI didn’t have any particular study guide ready for the test. Regardless of not having material, these are a few references I used to study for the exam.
PMI-ACP Exam Prep by Mike Griffiths is probably my book of choice for the exam. The explanations and examples are very well done and the book is easy to follow. I felt like there was plenty of information in the book to easily take the test. Furthermore, at the end of each chapter, there are a series of questions to test your knowledge on the chapter. The book also provides you with a code to access a 60-question simulator. Good for additional practice.
Agile Project Management with Scrum by Ken Schwaber is a very good book as well. It is a complete guide. Feels more like a bible with the amount of content in it. This book is definitely a good resource for the test and very valuable as a desk reference post-exam.
Coaching Agile Teams by Lyssa Adkins. I was quite content with this book. Although the content in the book is relevant on the exam, I feel it is more beneficial post-exam and can be a great desk reference.
The Art of Doing Twice the Work in Half the Time by Jeff Sutherland. Although this book is not on the suggested list from PMI for the PMI-ACP exam, it was an interesting read. This book brings a whole new flavor to talking about Scrum. Jeff uses many stories to explain the concepts throughout the book. It is definitely a good description of Scrum in action, but it does not go in-depth into Scrum concepts. Most of the book is Jeff’s stories using Scrum; the last ten pages are devoted to explaining how it, in fact, works. Good read for the stories but not for learning Agile, and more specifically Scrum, for the exam.

If you are on a budget, or strapped for time, and can read only one book, I would go with Mike Griffiths PMI-ACP Exam Prep Second Edition. You can’t go wrong there. Hope this helps in your PMI-ACP exam preparation. If you have any questions, comments, or any suggestions on content I should add, please feel free to contact me.
