This manual, Department of the Army Pamphlet DA PAM 600-25 U.S. Army Noncommissioned Officer (NCO) Professional Development Guide December 2018, serves as the medium to provide Soldiers and enlisted centralized selection board members professional development guidance for noncommissioned officers (NCOs) within their respective career management field (CMF). Civilian supervisors also need to understand the professional development guidance for NCOs to assist them in their career advancement. This guide serves as a framework for NCOs, warrant officers, officers, and civilians alike to offer advice and counsel NCOs on their professional growth and development. This pamphlet should not be construed as a simplified checklist for promotion selection or a guide for NCOs on how to perform their assigned duties. Instead, this guide serves to supplement the Army's various strategies on leader development, including the NCO 2020, talent management, and the human dimension strategy. It provides guidance intended to develop the next generation of competent and committed NCOs of character who are capable of meeting the challenges of operational adaptability in an era of persistent conflict within an All-Volunteer Army.
