Selection Process

In late October, applicants will be contacted by phone for a brief discussion to ensure understanding of the training requirements. We will schedule an in-person interview at this time.

After completion of the in-person interview, a panel of Master Gardener Volunteers and Loudoun County Extension Office staff select Applicants based on an evaluation of their enthusiasm to learn, their willingness to volunteer and contribute to the Extension Master Gardener program, and their interest in promoting environmentally sound management practices. 

Successful Applicants are admitted as Trainees once the personal references are checked and the background screening is complete. Classes begin in late January.  The fee is determined annually based on costs, which covers the electronic copy of Extension Master Gardener 600-page Handbook, classroom materials, the Pest Management Guide, and a state association membership.
