The AASHTO Accreditation Program's published service expectations are as follows: "We strive to provide excellent service to our customers by being professional, accurate, competent, and timely. We expect staff to always communicate to our customers in a professional manner, provide detailed analysis and responses to customer inquiries, and review assessment corrective actions within two weeks of receiving them from the laboratory. Our goal for responses to emails and phone calls is two business days, but keep in mind that we will only call you back if you leave a message."
