ISA offers a variety of educational materials and products to help arborists expand their professional knowledge and experience. Every month, ISA will feature a product or group of products. In January, ISA will feature the Arborists’ Certification Study Guide, Fourth Edition by Sharon J. Lilly, Corrine G. Bassett, James Komen, and Lindsey Purcell.

The fourth edition of Arborists’ Certification Study Guide is a must have and provides a strong foundation and reference for all tree care professionals. Available in print, digital, and audio formats, and in Spanish translation, this publication is a complete and up-to-date resource designed to help people study for the ISA Certified Arborist® exam. 

You can prepare for the exam using the Arborists’ Certification Practice Exam. This 200-question Practice Exam is a great way to help pinpoint areas of knowledge gaps, alleviate test stress, and nurture self-confidence. Want extra practice? Try Arborists’ Certification Practice Exams 2, 3, 4, or 5, each with different and unique practice questions. Additionally, ISA credential holders can earn CEUs with successful completion of the practice exams.

Please note: Any educational or preparatory material, whether published by ISA or not, should NOT be considered the sole source of information for an ISA certification examination. This publication and the ISA certification program exams are developed through separate processes and entities.
