The Power Sweeping Standard and Certification Each program and certification path is designed to equip managers, power sweeping operators and office employees with the necessary knowledge of industry standards and best practices. April 28, 2021 ANSI approved a national guideline for best practices in power sweeping, a standard largely written by NAPSA to codify objective, minimum criteria for competence, ethics and acceptable practice. The establishment of a national standard also sets the bar for training: we can train to the standard. The approval of a standard for minimum criteria does not, of course, preclude anyone from exceeding that minimum or contractors from training their employees to higher levels of professionalism.
