New Digital Version of Arborist Certification Study Guide Now Available

ISA offers a variety of educational materials to help arborists improve their arboricultural knowledge. Each week we will feature a product, or group of products that will enhance your arboriculture education. This week, ISA is featuring the newly released digital version of the Arborists’ Certification Study Guide written by Sharon J. Lily.

The fully illustrated must-have book for arborist is now available in a digital format. This online resource maintains the popular look and feel of the current print version, including all of the illustrations, while also providing enhanced features including a searchable table of contents which takes you directly to the chapter of interest. This great resource can be accessed anywhere and, best of all, there’s no wait on delivery!

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.
