Arboriculture 101 is a course given by the CTPA two times a year for those wishing to advance in the field of arboriculture and to prepare for the Connecticut Arborist License exam. It is given one night a week for thirteen weeks. Each class session is 3 hours in length.
One class session begins in early January; the other in early September.
This course is intended to provide the successful graduate with the basic information essential to a career in arboriculture. Students who attend class, read the assigned materials and work with the instructors can also expect to do well on Connecticut’s Arborist Licensing Exam. However, the course’s main goal is to provide that foundation that will assist individuals as they move forward in a career in arboriculture.
In order to get the most from the course, students must make a commitment to studying. They must spend the time and effort needed to learn the covered material. Readings are assigned in advance of each class. Students are expected to complete these reading assignments.
About the Instructors
The instructors are drawn from throughout Connecticut’s tree care industry. Also included are several scientists from the Connecticut Agricultural Experiment Station.
This variety in instruction is one of the key strengths of the course. It helps give the student a variety of perspectives that serves to reinforce the knowledge gained.
