President’s Letter

Jeffrey M. DeFrain, PhD, PAS, DPL ACAS

This time of year brings about the USDA Prospective Plantings report. This report describes how many acres of each crop will be planted and, pending no major weather events, harvested. This report is among the likes of our organization as members work together not only to develop ways to support existing members but to strategically devise plans to plant seeds of organizational growth of ARPAS. We are all set to gather at our ARPAS annual meeting in Baltimore, Maryland, at the ASAS–CSAS annual meeting, where we will review activities of the past year and discuss avenues of change that will allow us to further enhance our professions through ARPAS membership.

CEU’s-Alternate Ways to Meet Your Annual Requirement

Some of our members have difficulty meeting their required 16 CEU each year. Time and travel are becoming more expensive, and attending meetings that provide educational material to acquire your CEU is becoming more difficult. As an alternative, a portion of your continuing education could come from webinars or educational videos.
